Slow Motion Repair...

Work on the rear engine seal has slowed to a crawl, unfortunatly. Several other life priorities have come up and so she's still not torn down yet. Cleaned a few parts last night, pulled the battery and battery tray out, drained the drive shaft oil and removed the 4 drive shaft bolts. Hope the get the swing arm pulled back tonight and pop the trans out.

No real reasone to hurry, no plans until mid July when I plan to truck PROJECT-S to Corvallis Oregon to visit with the grand baby and attend the BMW MOA Ralley in Salem OR, just up the road a bit from Corvallis. May ride her to Portland to visit sister or maybe, perhaps, Seattle to see my mother (who still worries that I ride "those dangerous motorcycles").

Now we know...

Pulling the clutch.


Loosening the flywheel bolts.


And what do we have here... seems the oil pump cover was leaking, and not the rear main seal above. Will replace both of course.
Oil pump cover bolts were "finger tight" Black o-ring (likeley the original) was flat as a pancake.

Clutch time

Measured the VERY THIN clutch friction plate, .115" = 2.9mm!

New friction plate should be 6mm, according to Clymer...

Minimum service limit 4.5mm, also according the Clymer.

So I'm 1/2 the original thickness and 1.5mm below the minimum.

Clutch time

Recommendations? Anyone? Anyone? Bueller?

I put in a BMW heavy duty clutch. The one I took out had little wear, but was cracked. It was some kind of an aftermarket affair. Of course I have not had it in long enough to know, but everyone here tells me the BMW clutch is the way to go.

The BMW clutch was labeled Sachs if that helps.

Don't some folks swap 200mm VW beetle clutches too?

Those doods ARE great. And if they don't have it, it's usually only a couple days out.

Seal is Out

Rear main seal is out and the bell housing has been cleaned up and is ready for reassembly.


For added insurance, before I applied pressure to the crank to pull out the old rear main seal I added a strap to the crank blocking tool.



Rear main seal tool worked like a champ. Original seal is the old style with the spring.


Found this o-ring (that I forgot to order) inside the flywheel

This would be a good time to get that boat anchor of a flywheel lightened, don't you think ?
And you did replace the oil pump cover O-ring, correct ?

Tell you what, just take mine for a spin and see if you like the way the engine revs and the transmission shifts.
