Clutch Oil Seal Location
Posted 13 July 2019 - 07:41 AM
The engine is out of the car and I’ve just fitted the gearbox, before putting the flywheel housing on I want to put a new oil seal in and the workshop manual and Haynes just say drift it in. Should it go in so that it is flush with the edge of the housing facing the clutch/flywheel or sit a bit proud?
I could fit the housing and bang in the oil seal then - I have the mini spares tool - would that be better and naturally seat the seal in the right place?
Sorry if this is a stupid question!
PS MPI Mini if that makes a difference.

Flush is accurate enough. If you do not have the clutch seal tool just wind plastic insulation tape onto the primary gear from where the seal would run until the end of the splines. The thinner the tape the better. Wipe engine oil over the insulation tape and the oil seal lip and gently push on the transfer case home.
Do a trial fit first without the seal to ensure the transfer case fits on smoothly, sometimes the two locating suds need to be sanded down slightly and it helps to put grease on the primary nose bearing.
Note no hammering of the transfer case to force it on.
Trust you have checked the idler gear and primary gear floats?

It should NOT sit proud of the casing.
Grease the seal and the casing and push it in with your thumbs.
I have never had a super device like imack, I go round the seal, tapping it in with a length of hardwood rod until it is sat against the flange, when I know it is square to the crankshaft.

Yes, I’ve checked the idler gear and primary gear floats and done a trial fit of the housing - the dowels were a bit tight but no hammering necessary!
First time I’ve done this so trying to be SO careful!
