Re: Rear Main Seal

Joe,

I read all through Tobs blog on his rear main seal replacement and got up to speed on the process. I did not realize that the seal was accessed from INSIDE the oil pan. From my very limited knowledge and experience on rear seals, I wanted to ask (probably at the risk of sounding stupid!) why the tranny should come out? It just rests in the pilot bearing recess of the flywheel and would rotate easily in neutral, to turn the crank, while feeding the new seal in to the cavity - what purpose would NOT having the transmission in place, serve?? (possibly crank end play?) Never having done a R.M.S. I presumed it would fit into a recess on the exterior of the block, behind the flywheel - thus my previous thoughts on removing the clutch. Once you do get the leak stopped, I'd sure still consider putting a new clutch disc in, as no matter how degreased you can get the surface of the old one with brake cleaner, if the sintered fibre is oil soaked, it could still give you trouble down the road with slippage and chatter. I learned that one the hard way and had to tear everything back down and redo it all with a new clutch. You'll be going through enough work here, you sure won't need that! Chris.
