Major oil leak !

Subject: Major oil leak ! Tue Aug 23, 2011 3:56 pm

My clock says 75,000 miles
Last time I changed the belt was at 30,400 miles.
I drive very conservative.

A couple of days ago, middle lane, going 60...pop.
I go to flap my arms like a mad man to stop the traffic.

About two week ago I found two oil spots on the left side of the bike. I new I have a problem I just didn't know is going to go from bad to worst that fast.

Long story short, oil got to the belt and it popped.

I just ordered:

13312-MCT-000 COLLAR, L. CRANKCASE SIDE
91201-MCT-003 OIL SEAL (39.8X64X7)
91302-PC9-003 O-RING (22.5X2.7)

I hope that I can just pop out the seals with the screwdriver and put the new one in.

Have you guys had any problems like mine ?

If you want to see how it looks I have uploaded some pictures to the link below.

Yes, I did, but at about 14,000 miles. I thought it was the final drive leaking but when i took it all apart it turned out to be the rear main seal. I believe I am the only person with experience with this repair as nobody had seen it before it happened to me.

Sorry to have to tell you this but if you want to replace that oil seal you need to remove the belt case entirely from the bike. The outer diameter of the oil seal is a bit larger than the inner hole of the bearing plate in front of it. It wasn't too difficult to remove the belt case but there are a lot of steps- contact me if you need more specifics.

It is possible that the collar and O-ring are bad, not the oil seal and those you can just swap out, then check to see if the leak stops before you have to do the big job of changing the oil seal.

BTW absolutely do not start the bike without the variator in place and torqued down to the proper torque setting- the variator holds that collar and O-ring in place and without it the oil will leak all over the place from that rear seal.

I would recommend ordering the 6 allen bolts that hold the bearing plate to the rear of the engine- they are a soft metal and 3 of the 6 rounded out when i tried to remove them- what a pain.
