Airbox Part numbers

hello all,

I was doing some surfing on air box part numbers. Trying to see if any other yahama model used the same intake as my xj550. So in my surfing the part number for my airbox is 5k5-14401-01-00. So I surfed up through the years and couldn’t find any that used the same part number.

Until I happend Ed to click on the 1986 radian yx600. This has the same part code as the 81 xj550.

Does anyone happen to know if Yamaha recycles part numbers or would this maybe be the same airbox?

Sorry newbie and I’m just reading up and learning as I go.

 

Same part number with yamaha is same part. Hands down. ATV Bike Sled whatever.

However, i have found over the years they sorta use a code.
5K5 is the series... Or model, so. Most parts for that bike, unless they share from a earlier version will be 5K5
(Radian is newer, shares the box, retains old series)
Middle number 14401 is the part, no real substitutions.
Last didgits -00-00 are run numbers or change ups, they sometimes will interchange.
Example -00-00 made in 1983 -01-00 made in 85 still fits -01-01 made in 85 modified once still fits.
***** this however is not always true, im missing something from the japaneese part number algorythim****
Generally though it works.
XJ forever is going to correct me on this probably... Lol!

 

Well that’s what I was curious of. I can’t see them reusing part codes. Would get too confusing. The Radian part number is exactly the same from what I could see. Just wondering as they are newer and maybe easier to track down the box for them instead of an older XJ.

Figured I’d ask the experts if it was the case.

 

Yup, some older parts even cross ATV Sled, Bike. (Like a solenoid or brakes)
Lol! My 1978 DT175 has the same swing arm bushings as Yamaha ATV A-arms in the mid 80s
They dont now as much, just to make life harder, but yamaha was always the best for recycling old parts and part numbers to match.

 

Pop the part number in the search by part number box, then click the "where used" text to see everything that Yamaha used that part on.

The Radian was a short-lived model, and essentially a "redid" Maxim 550.

 

That is a nice feature. Thank you for the tip. Least now I know what to target in my searches at the local salvage yards. More options the better.

81-1990... Lol! Love Yamaha!

 

As mentioned before as per part no 5K5-14401-01-00
5K5-14401-00-00
Or a 5K5-14401-01-01 may fit if that part number even exists... Yamaha us wierd like thatl
Maybe even 5K5-14401-02-01

 

Or 5K5-14401-02-00

 

5K5 (first 3 positions of any part number, besides hardware) designates what bike model the part was originally specified for. In this example, this airbox was first used on a 1981 XJ550 Maxim (which is a 5K5 model).

The next 5 positions (14401) is the specific part "type".........so all traditional 1-piece airboxes have the 14401 "part number". Note that this pattern carries across model numbers, so for instance, an XJ650 Maxim/Seca airbox is 4H7-14401, and the 1981-83 XJ750 airbox is 5G2-14401. Now, if an "airbox" was of a 2-piece design, where there is actually a top and bottom section needed to make a complete "airbox", then the top section would be a different "part type" (example: 14411) and the bottom section would also be a unique part number (14421). And again, when combined with the first bike model 3-position pre-fix, then you have defined a unique part:

Airbox case top section, XJ1100: 10M-14411 (10M being the model code for an XJ1100 model)
Airbox case top section, XS1100: 2H7-14411 (2H7 being the model code for an XS1100 model)

Airbox case top section, XJ1100: 10M-14421 (10M being the model code for an XJ1100 model)
Airbox case top section, XS1100: 2H7-14421 (2H7 being the model code for an XS1100 model)


The next two positions indicate (typically) any engineering design changes to a specific part. For example, on the XJ550 Maxim airbox (5K5-14401), the initially designed and installed version would be the "00" version: 5K5-14401-00 If there were subsequent "revisions".....which could be an almost unlimited type of "changes" (a different plastic material, an extra hole drilled and tapped, a refinement to the air filter holder bracket, perhaps even a change in outside supplier, etc.)....then each unique change increments the number by 1 unit (01, 02, 03). BTW, it is almost impossible to determine what the "change" may be, unless you get a hold of internal engineering documents (or the change becomes apparent). NOTE: these two positions can also be used to differentiate between a left and right side version of the "same" part (such as brake calipers) or front vs. back. top vs. bottom, etc. This method somewhat contradicts the overall "part interpretation philosophy" as outlined above, but when there's a will there is a way (even if not always the best or most consistent way..........).

For example:

Left and right brake caliper assemblies: obviously, a left caliper is not the "same part" (physical object) as a left caliper, and as such, should carry a different 5-position "part ID code" (like the top and bottom sections of the air cleaner case on XJ1100 models as discussed above). BUT, that is not how it is usually done. One would think that the "logical" way to do it would be as follows:

LH caliper: (model ID)-25810-00
RH caliper: (model ID)-25811-00

See how the "part ID" is different between LH and RH calipers: 25810 vs. 25811 ?

But that is not typically how it is done. What you normally (but not always!) find is the following:

LH caliper: (model ID)-25810-10
RH caliper: (model ID)-25810-20

Notice how the "part id" (25810) stays the same, and the LH vs. RH designation becomes a part of the "engineering changes" designation (-10 vs. -20). This method "works"......the LH and the RH caliper assembly still retains a unique part number ID, but it can be tough on countermen and parts peddlers, mainly because it is used inconsistently. Also note that actual "engineering changes" to the calipers can also be used in this scheme:

LH caliper, original version: (model ID)-25810-10
LH caliper, first change: (model ID)-25810-11

See, the -10 became a -11. Okay, so now in that 2-position field we're now accounting for both a position designation AND engineering changes....one "field" of the part number now has 2 (or more!) different "meanings"..........


Finally, the last two positions of a full part number typically indicate color or other finish, or, anything else that might be "logically" different about a part. Example, XJ700 Maxim front fenders:

Black fender: 42X-21510-00-6G (XJ700 front fender black)
1985 fender: 42X-21510-00-63 (XJ700 front fender 1985 Super Red color)
1986 fender: 42X-21510-00-MV (XJ700 front fender 1986 Red-E-Sparkle color)
1986 fender: 42X-21510-00-MV (XJ700 front fender 1986 Bluish-black color)

So, since it's all one particular style front ender (21510), first used on a 42X model bike (1985 XV1000 Virago), there have been no design changes to the fender (-00), and it's painted in the Super Red color (-63).


Note: hardware (screws, washers, nuts, cotter pins, etc.) and "universal parts" (wheel bearings, etc.) typically have a completely different type of part numbering system (95811-10030-00, for example), which has some "coded" info contained within the part number, but some info is not. Here's the scorecard:

12345-67890-xx

123 = hardware type (bolt, nut, screw, etc.)
4 = material
5 = finish
67 = diameter (for a washer this is the ID)
890 = length, size
xx = added 00 to complete 12-digit part number scheme


2nd position:
0 = various types
1 = bolts, cotter pins, etc.
2 = screws, nuts, etc.
3 = oil seals, o-rings, bearings
4 = spark plugs
5 = bolts and nuts
7 = ISO bolts
8 = ISO screws and nuts

It is NOT possible to ID the length of a bolt having a 901 prefix.


Also, some fasteners carry the longer part ID code as explained at the beginning (in the example with airboxes, calipers, fenders), although this only usually occurs for very unique, specific-to-a-particular-bike type of fastener or hardware, i.e. the very odd-shaped and design "washer" that is used at the upper mounting position of the rear shocks on XJ700 Maxim models.............although it's a washer, it's a very ODD washer, so it carries a "long" part number (42X-22243-00-00) rather than a typical "common standard washer" type of part number (90201-08100-00.....which is a flat washer (902) made of carbon steel (0) with a znc-plated finish (1) that is an M8 size (08) with a 1.00mm thickness (100), and the last 2 positions are meaningless (00) and only used to complete the full 12 positions needed to be a part number in Yamaha world (note that 42X-22243-00-00 and 92901-08100-00 are both 12 total positions).

 

Makes since. Keep the same base and add characters for revisions. This would allow them to keep base item intact and revise if need be. I guess in a sort of way they do recycle part numbers with alterations appended to the end. Simple way to do it. Wish the part codes my company uses were like that lol. Thank you for the information.

 

All smart manufacturers get the most life theat they can out of a part. Design, and retooling for production are both very expensive.

 

Well, I went to a salvage place today. Guy sai he had a few tubs of air boxes outside and I was welcome to root through. I walked out and there was ten, 4x4 bins full lol. I started sorting through. Low and behold on the last bin ( as it always works out) was two of them lol. I grabbed them both and ran lol. 25$ for the pair. Can’t go wrong there.
