Oil Seal for Drive Sprocket

[Sour1]

Hey, guys.  Finally got some time for the FJ again. I got the undercut gears (don't ask) in and ready for putting the crankcase back together.  I don't have a new oil seal for the shaft that holds the drive sprocket. Can I put a new oil seal on afterwards? Or does it have to go on with the gears?

Thanks.

New seals can go on after assembly. Randy has them for a good price if you don't already have it.

It can be installed after the cases are assembled, but if you have them apart you should install it then. The seal has a small lip that assists in holding the seal in the case.

It is much easier...

Old thread I know but this appears to be best place to post this question.  I have the new oil seal that fits behind the drive sprocket and I am assembling the two halves of the crankcase.  Whilst performing a 'dry run' of the assembly I notice that the oil seal does not fit snug to the diameter of the shaft on which the drive sprocket is located, there's about a quarter inch gap all around.  Is that correct and, if so, onto what does the lip of the seal perform its sealing? (see linked picture)

There is a collar that went over the transmission splines and contacts the seal.

It was there when you took it apart as the sprocket was installed.

I will have to take a picture of it tomorrow. I just went out and looked at your oil transmission and it is not there. (I keep it out as a reminder to keep in touch with USPS...)

It is #27 here:


I always tell people to remove it before shipping it so you have it and it does not get lost.
