Below you will find an assortment of OE-quality ENGINE GASKET KITS, OIL SEAL KITS, O-RINGS KITS, and HARDWARE KITS that will make your engine service work easier and more affordable. Many of these products are produced by an OEM gasket supplier, and the gasket kits contain all of the major items needed either when doing a head service, piston re-ring, or cam chain replacement in the TOP-END GASKET KIT. Additionally, all of the major side cover gaskets are also included in a ENGINE REBUILD GASKET KIT.

Head gaskets are made of a graphite material and feature a steel core and are resistant to 500-degrees Celsius, making them of outstanding quality and durability, while all other major gaskets are made from Klingersil AC11-600 or Garlock 3760 material, generally acknowledged as the finest gasket materials available in the market today. ALL of the gaskets are asbestos-free.

The same comprehensive assortment of needed o-rings and crush washers are included in our TOP-END O-RINGS & CRUSH WASHERS KITS and the ENGINE REBUILD O-RINGS & CRUSH WASHERS KITS. And the same quality and completeness can be found in the
TOP-END HARDWARE KITS and the ENGINE REBUILD HARDWARE KITS, which contain the proper assortment of the alignment pins and collars used in various places.

And of course our complete ENGINE REBUILD OIL SEAL KITS contain all of the heavy-duty oil seals used in your engine, and helps assure that your rebuild job is complete and results in leak-free operation.

Note that in all cases, in order to obtain ALL of the items to do a complete job, you will need to purchase a combination of a gasket kit, o-ring and washers kit, an oil seals kit, and the appropriate hardware kit.


Obviously, if you need just one or two specific gaskets, then our line of individual OEM or aftermarket gaskets are just the ticket for you.

And finally, don’t forget the use of proper ENGINE TOOLS and CHEMICALS necessary for the proper tear-down, cleaning, and re-sealing of the various gaskets and seals.


TOP-END KITS contain all of the parts needed when doing anything except an engine case teardown……..so they contain all the items needed when performing service work on the cylinder jugs, heads, and cams. There are no engine side covers, oil pan, nor any internal or external engine case items included in the top-end kits.

COMPLETE ENGINE KITS contain all of the items in the top-end kits, plus all of the other necessary items when performing a complete engine teardown.


By the way, the firing order for the XJ550 thru XJ900 engines is 1-2-4-3, with the two center pistons coming up while the two outer pistons are going down, and the direction of engine rotation is in the same direction as your tires rotate when moving forward.

HCP25091 Aftermarket clutch cover-to-block hi-performance GASKET, for all 1992-98 XJ600 Seca II and 1992-2002 XJ600 Euro models. NOTE: Yamaha obviously had some machining issues with the original crankcase and/or clutch cover on these models, as the original gasket contains a 6” long patch of gasket sealer material on one section of the gasket. These replacement gaskets do not include the sealer, and should not need it due to their ability to slightly “swell” in the presence of petroleum fluids. However, it would be a good idea to also treat this gasket with a very thin film of our HCP25092 non-hardening gasket sealant material or similar product.

HCP17542 Aftermarket valve cover pressure washer INSTALLATION TOOL........a lifesaver little device to make quick and easy work of installing the HCP1621, HCP1622, HCP19931 pressure washers into their bolts, and useful (but not absolutely necessary) on the HCP1620 pressure washers. This tapered brass collar is the proper size to allow the pressure washer to easily slide over its retaining flange or "ring" on bolt, eliminating the grinding ordeal of trying to press or wedge the new washer over that flange (it ain't easy!).

NOTE: This o-ring does not fit down into the cavity where the tensioner locking bolt goes into the body of the tensioner case; that cavity has a double-chamfer, and the HCP2173 washer (above) on the bolt stops against the locknut-threaded portion. When you tighten the adjuster bolt itself, that washer presses the o-ring against but not completely into the outer chamfer to seal it. Once this o-ring gets dried out and hard, it can be pressed all the way into the cavity and it stops doing its job and a thus a common source of oil leaking develops there.

Here's a good write-up on changing the alternator shaft oil seal on a later model Yamaha (XJ600 Seca II).....although the procedure is not exactly the same on the 1980's XJ-series engines, it's close enough to show the entire process, and with very good pictures:

http://www.xjrider.com/viewtopic.php?t=2101

And here is the procedure shown on an XJ700 engine, other XJ engines of this era are very similar in procedure:

NOTE: the crank seals below no longer have the original flanged mounting lip, so they can be installed without splitting the cases, but the removal of the original flanged seals can be a real challenge without splitting the cases.......these are the best videos that we could find to show the process, although the author failed to show the most important part (!)----how to dig the old flanged seal out of the cases. However, at the beginning of the 2nd video, he does show what that flanged seal looks like (after extraction), so you can get an idea of what you're working with, and have an idea of what it will take to dig-pry-distort-tear apart the old seal (carefully, of course....) during the removal process:

HCP26484 OEM crankshaft flange OIL SEAL, fits on the right end of the crank to the case on all 1992-98 XJ600 Seca II and 1992-2002 XJ600 Euro models. NOTE: this version of the seal has a base flange or “lip” to secure it in the recessed land machined into the crankcases. This lip provides more security for the seal, but makes it difficult to remove without splitting the case, and impossible to install without splitting the cases. If you need to replace this seal with the engine still intact, you should use the HCP22542 seal below, as it is the same seal but without the “lip”. Use 1 per engine.

NOTE: this version of the seal lacks the base flange or “lip” to secure it in the recessed land machined into the crankcases. The originally-installed seal (HCP26484 above) features the retention lip and provides more security for the seal, but makes it difficult to remove without splitting the case, and impossible to install without splitting the cases. If you need to replace this seal with the engine still intact, you should use this HCP22542 seal, as it is the same seal but without the “lip”. For split-engine situations, we recommend using the HCP26484 original flanged seal. Use 1 per engine.

We recommend the following accessory kits to compliment the above gasket kit:

HCP21192 Aftermarket engine rebuild OIL SEALS SET contains the six oil seals needed when doing a complete engine rebuild, and should be ordered as a complement to the HCP5463, HCP5464, HCP5465, HCP5466, HCP22336, or HCP26721 gasket kits. It is recommended that if the engine is coming apart, that new seals go back in to insure case integrity. NOTE: the only difference between the HCP21192 kit and the HCP21196 kit is the inclusion (or not) of the HCP20944 middle driven gear output shaft oil seal: the HCP21196 kit includes this seal, while the HCP21192 kit does not include (and those engines do not use) the HCP20944 seal. Sometime in the mid-80’s (impossible to say exactly when) Yamaha stopped machining the recess into the upper and lower engine cases that accept this seal --- they eliminated the seal completely from the assembly --- and thus the seal is no longer used in those engines. The applications below are known to be correct; however, some of the non-North American XJ650 and XJ750 engines we do not have complete information on. If in doubt (or you haven’t taken your engine apart yet), then order the HCP21196 fit, as it contains the HCP20944 oil seal if needed; and if not, you can discard it.

Contains all of the following seals:

- 1 x shifter shaft oil seal
- 1 x clutch pivot shaft oil seal
- 1 x alternator shaft oil seal
- 1 x middle gear output shaft oil seal
- 1 x left side crankshaft end case oil seal
- 1 x right side crankshaft end case oil seal

This tapered brass collar is the proper size to allow the pressure washer to easily slide over its retaining flange or "ring" on bolt, eliminating the grinding ordeal of trying to press or wedge the new washer over that flange (it ain't easy!).

NOTE: This o-ring does not fit down into the cavity where the tensioner locking bolt goes into the body of the tensioner case; that cavity has a double-chamfer, and the HCP2173 washer (above) on the bolt stops against the locknut-threaded portion. When you tighten the adjuster bolt itself, that washer presses the o-ring against but not completely into the outer chamfer to seal it. Once this o-ring gets dried out and hard, it can be pressed all the way into the cavity and it stops doing its job and a thus a common source of oil leaking develops there.

HCP5120 OEM middle gear oil drain bolt CRUSH WASHER, fits all XJ650, XJ700, XJ750, and all XJ900RK, RL, N/FN, and F models. NOTE: although Yamaha recommends draining the oil from the middle gear drive area during each oil change, we STRONGLY recommend against doing so. The middle gear drive drain bolt is extremely hard to get at while the exhaust is on the bike, and it is rather fragile and easy to shear off when attempting to loosen. It is really intended to be used as a drain port when the engine is out of the bike, before splitting the cases. The middle gear area that this port provides access to only holds about a half-cup of oil7 and that oil will be "changed" via mixing with the fresh oil added to the crankcase during an oil change.

NOTE: if you are getting a leak under the bike, you can confirm whether this seal is the source via disconnecting the oil line from the outside of the oil pan (leave the oil in), and insert some 6mm OD clear tube through the pan and into the oil pump (thus by-passing this gasket). If oil leaks around the outside of this tube, then it’s this seal that is leaking. If the oil leaks from inside the tube, then the leak is internal to the pump, pump and is probably the HCP27594 shaft seal. Use 1 per engine. Each:
$ 11.95

HCP27594 OEM oil pump DRIVESHAFT OIL SEAL. The metal-cased seal fits into the spacer plate in the oil pump around the pump main shaft. Failure of this seal (typically caused by a sticking pressure relief valve in the pump) will allow oil to flow back to the turbocharger via the return line, thus filling up the exhaust when the bike is stored for more than a day or two. NOTE: this seal fits very tightly into the spacer plate, and it is advisable that the spacer plate (which is aluminum) be heated up with a heat gun, etc. to allow the aluminum to expand, before attempting to “pop” the metal casing of the oil seal out of its cavity. Be careful to not scratch or gouge the spacer plate when prying! Each:

Here's a good write-up on changing the alternator shaft oil seal on a later model Yamaha (XJ600 Seca II).....although the procedure is not exactly the same on the 1980's XJ-series engines, it's close enough to show the entire process, and with very good pictures:

http://www.xjrider.com/viewtopic.php?t=2101

And here is the procedure shown on an XJ700 engine, other XJ engines of this era are very similar in procedure:

http://www.xjbikes.com/forums/threads/replacing-alternator-seals-in-xj700n-with-pictures.108126/




NOTE: the crank seals below no longer have the original flanged mounting lip, so they can be installed without splitting the cases, but the removal of the original flanged seals can be a real challenge without splitting the cases.......these are the best videos that we could find to show the process, although the author failed to show the most important part (!)----how to dig the old flanged seal out of the cases. However, at the beginning of the 2nd video, he does show what that flanged seal looks like (after extraction), so you can get an idea of what you're working with, and have an idea of what it will take to dig-pry-distort-tear apart the old seal (carefully, of course....) during the removal process:

HCP5120 OEM middle gear oil drain bolt CRUSH WASHER, fits all XJ650, XJ700, XJ750, and all XJ900RK, RL, N/FN, and F models. NOTE: although Yamaha recommends draining the oil from the middle gear drive area during each oil change, we STRONGLY recommend against doing so. The middle gear drive drain bolt is extremely hard to get at while the exhaust is on the bike, and it is rather fragile and easy to shear off when attempting to loosen. It is really intended to be used as a drain port when the engine is out of the bike, before splitting the cases. The middle gear area that this port provides access to only holds about a half-cup of oil7 and that oil will be "changed" via mixing with the fresh oil added to the crankcase during an oil change.

Here's a good write-up on changing the alternator shaft oil seal on a later model Yamaha (XJ600 Seca II).....although the procedure is not exactly the same on the 1980's XJ-series engines, it's close enough to show the entire process, and with very good pictures:

http://www.xjrider.com/viewtopic.php?t=2101

And here is the procedure shown on an XJ700 engine, other XJ engines of this era are very similar in procedure:

http://www.xjbikes.com/forums/threads/replacing-alternator-seals-in-xj700n-with-pictures.108126




NOTE: the crank seals below no longer have the original flanged mounting lip, so they can be installed without splitting the cases, but the removal of the original flanged seals can be a real challenge without splitting the cases.......these are the best videos that we could find to show the process, although the author failed to show the most important part (!)----how to dig the old flanged seal out of the cases. However, at the beginning of the 2nd video, he does show what that flanged seal looks like (after extraction), so you can get an idea of what you're working with, and have an idea of what it will take to dig-pry-distort-tear apart the old seal (carefully, of course....) during the removal process:

We recommend the following accessory kits to compliment the above gasket kit:

HCP21196 Aftermarket engine rebuild OIL SEALS SET contains the seven oil seals needed when doing a complete engine rebuild, and should be ordered as a complement to the HCP5462 and HCP5465 gasket kits. It is recommended that if the engine is coming apart, that new seals go back in to insure case integrity. NOTE: the only difference between the HCP21196 kit and the HCP21192 kit is the inclusion (or not) of the HCP20944 middle driven gear output shaft oil seal: the HCP21196 kit includes this seal, while the HCP21192 kit does not include (and those engines do not use) the HCP20944 seal. Sometime in the mid-80’s (impossible to say exactly when) Yamaha stopped machining the recess into the upper and lower engine cases that accept this seal --- they eliminated the seal completely from the assembly --- and thus the seal is no longer used in those engines. The applications below are known to be correct; however, some of the non-North American XJ650 and XJ750 engines we do not have complete information on. If in doubt (or you haven’t taken your engine apart yet), then order this HCP21196 fit, as it contains the HCP20944 oil seal if needed; and if not, you can discard it.

Contains all of the following seals:

- 1 x shifter shaft oil seal
- 1 x clutch pivot shaft oil seal
- 1 x alternator shaft oil seal
- 1 x middle driven gear, output shaft oil seal (HCP20944)

It is recommended that if the engine is coming apart, that new seals go back in to insure case integrity. NOTE: the only difference between the HCP21192 kit and the HCP21196 kit is the inclusion (or not) of the HCP20944 middle driven gear output shaft oil seal: the HCP21196 kit includes this seal, while the HCP21192 kit does not include (and those engines do not use) the HCP20944 seal.

All of the following OEM paper gaskets are made from a standard duty, graphite impregnated paper material. We recommend the use of the aftermarket hi-performance gaskets which are designed to slightly swell in the presence of petroleum products (fuel or oil), thus creating a super-tight, leak-proof flange seal.

HCP17542 Aftermarket valve cover pressure washer INSTALLATION TOOL........a lifesaver little device to make quick and easy work of installing the HCP1621, HCP1622, HCP19931 pressure washers into their bolts, and useful (but not absolutely necessary) on the HCP1620 pressure washers. This tapered brass collar is the proper size to allow the pressure washer to easily slide over its retaining flange or "ring" on bolt, eliminating the grinding ordeal of trying to press or wedge the new washer over that flange (it ain't easy!).

HCP5120 OEM middle gear oil drain bolt CRUSH WASHER, fits all XJ650, XJ700, XJ750, and all XJ900RK, RL, N/FN, and F models. NOTE: although Yamaha recommends draining the oil from the middle gear drive area during each oil change, we STRONGLY recommend against doing so. The middle gear drive drain bolt is extremely hard to get at while the exhaust is on the bike, and it is rather fragile and easy to shear off when attempting to loosen. It is really intended to be used as a drain port when the engine is out of the bike, before splitting the cases. The middle gear area that this port provides access to only holds about a half-cup of oil7 and that oil will be "changed" via mixing with the fresh oil added to the crankcase during an oil change.

Here's a good write-up on changing the alternator shaft oil seal on a later model Yamaha (XJ600 Seca II).....although the procedure is not exactly the same on the 1980's XJ-series engines, it's close enough to show the entire process, and with very good pictures:

http://www.xjrider.com/viewtopic.php?t=2101

And here is the procedure shown on an XJ700 engine, other XJ engines of this era are very similar in procedure:

NOTE: the crank seals below no longer have the original flanged mounting lip, so they can be installed without splitting the cases, but the removal of the original flanged seals can be a real challenge without splitting the cases.......these are the best videos that we could find to show the process, although the author failed to show the most important part (!)----how to dig the old flanged seal out of the cases. However, at the beginning of the 2nd video, he does show what that flanged seal looks like (after extraction), so you can get an idea of what you're working with, and have an idea of what it will take to dig-pry-distort-tear apart the old seal (carefully, of course....) during the removal process:

HCP5120 OEM middle gear oil drain bolt CRUSH WASHER, fits all XJ650, XJ700, XJ750, and all XJ900RK, RL, N/FN, and F models. NOTE: although Yamaha recommends draining the oil from the middle gear drive area during each oil change, we STRONGLY recommend against doing so. The middle gear drive drain bolt is extremely hard to get at while the exhaust is on the bike, and it is rather fragile and easy to shear off when attempting to loosen. It is really intended to be used as a drain port when the engine is out of the bike, before splitting the cases. The middle gear area that this port provides access to only holds about a half-cup of oil7 and that oil will be "changed" via mixing with the fresh oil added to the crankcase during an oil change.

Here's a good write-up on changing the alternator shaft oil seal on a later model Yamaha (XJ600 Seca II).....although the procedure is not exactly the same on the 1980's XJ-series engines, it's close enough to show the entire process, and with very good pictures:

http://www.xjrider.com/viewtopic.php?t=2101

And here is the procedure shown on an XJ700 engine, other XJ engines of this era are very similar in procedure:

http://www.xjbikes.com/forums/threads/replacing-alternator-seals-in-xj700n-with-pictures.108126




NOTE: the crank seals below no longer have the original flanged mounting lip, so they can be installed without splitting the cases, but the removal of the original flanged seals can be a real challenge without splitting the cases.......these are the best videos that we could find to show the process, although the author failed to show the most important part (!)----how to dig the old flanged seal out of the cases. However, at the beginning of the 2nd video, he does show what that flanged seal looks like (after extraction), so you can get an idea of what you're working with, and have an idea of what it will take to dig-pry-distort-tear apart the old seal (carefully, of course....) during the removal process:
