Installed rear main seal today. Well, probably installed it. Almost square and flush with the casing. Might be 1/4 of a mm less in on the top but cant get it further in. Used the old seal and a plastic hammer and the plastic hammer directly on the seal...small taps. Did not damage it.

But busted up my thumb. Why is everything so cramped on the 928?

Hope that the install od the clutch goes better.

Cheers,

Christian

Sorry 928, I dont hate you - but my thumb hurt

I have a saying about working on my car - if my knuckles aren't bleeding, I'm not working!

Didn't you know that these cars are assembled by Elves from the Black Forrest. That's why you can never get your hand "in there" to work on things.

Well, I still believe that no repair is really hard, it's the sequence of doing things that makes it hard. It can't have been too hard building the car fom scratch. It's just that all kinds of parts are blocking access to the part that needs fixing. Sorry, no offence meant. I think I took it too far by almost dismantling the complete car to gain access to that one part....

So true!

So true! I would love to have the build sequence for these things!! Maybe a trip to the motherland, track down a factory worker, several beers later and these things will all make sense!

In my limited experience, a rear main that is at all noticeably crooked in the housing will leak. The lip on the seal needs to have no axial deflection at all when the crank spins inside it. It also depends on a very thin layer of lubrication where that lip rides on the crank, so the back of the lip will scrape off any lubrication as it spins and cause it to fall off in drops.

There are probably a few creative ways to install the RMS straight. Tapping it in with a hammer is not one of those. Even a driver made from plastic pipe fittings will do, pushed with a pry or roll-head bar, or drawn in with the flex plate if it's an automatic. I confess that I haven't swapped a 928 RMS, but can claim bad results with other cars when I thought a marginal installation might be 'good enough'. Good enough to do over.

Easy answer is to just lift the body off, and have all the mechanicals resting in a full factory jig, anytime you want easy access to everything. It would have been easier if I'd done that rather than taking mechanicals out item by item ... until I ended with just a body shell.

that would be cool !!!

To make things worse is if you don't have the space to put all the parts that you took out.....

Well, the seal is seated square now....the car is tilted heavily, so I guess I would have seen a leak over the past few days if it was not seated right.

Will put all things together over weekend - flywheel is on but clutchpack still heavy and pointy without it. If I never post again you know what happened......

Thanks guys.

Correct if not seated past the "notch" in the block it would be leaking w/in minutes. (BTDT)
If its not installed "true" to the Crank it will eventually leak.

Note: there are two Brands of Seals, some are full rubber coated and some have metal showing (on the outside edge).
The ones w/the the metal showing need to be installed deeper into the block to ensure the "notch" is covered by the rubber.

Depending on the repair I sometimes have to go to church the following Sunday for confession due to the extent of cussing that went on during the repair.

For sure, and it doesn't help when you have the hands of a Giant ! LOL
