Oil leak under strange mechanism

Hi, guys!

There is an oil leak under this mechanism.
I believe there is an oil seal behind it, I was not able to get under it.
Is it possible to change easily or may be some difficulties in process?

Thanks

 

Crank end seal is what it looks like.
May require splitting engine. If I remember correctly it has a lip on the seal fitted to a groove in the case.

 

I think there is a seal you can get with out the lip for the groove so that you do not have to open case it goes in with a yamaha sealer.

ask @chacal if he sells them

those strange things are the pickup coils that fire the tci

 

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.......

May be a silly question, but...Is this a left or right side seal?
Thank u for this useful info!

 

top 2 listings are left side bottom 2 listings are right side

you need left side
also the numbers are xj4ever numbers.


yamaha part number
right side is shown in gasket drawings

Plug, Blind 4H7-15167-10-00

left side is on crankshaft drawings

Oil Seal 93101-32144-00

 

I've checked the size of oil seal...it is 32x45x6.5 according to catalogue. Found similar in my city, but with less hight 32x45x6
Will it work out installing this one instead of the original one?
Thanx

 

The final number is the thickness or height, you can use a thinner seal no problem, they just wear faster, but not enough to care about. Be sure to use a sealer (Permatex Mototseal, Yamabond etc.) and don't accidentally jam it in crooked or you'll be buying a new seal and doing it twice.
