My MC54-250b developed a large oil leak on Sunday. It was running out of the Transmission cover onto the rear tire. So i get her on the lift and pull off the cover and the variator to find a silver hex head bolt with the thin flat head of the bolt about the size of a dime. It was sealed with a piece of plastic (like an o-ring) and it cracked and failed. I installed a fiber gasket and the oil leak is gone. My question is what does that bolt do for the engine?

[replyingto=quail]quail[/replyingto]it is behind the variator and leaks motor oil. I am not going to tear it down just to take a photo.

Sound like the HEX BOLT that holds the Chain Tensioner GUIDE. It is about 1-2 inchs above the Crank.

Ok...behind the variator itself...sometimes it is confusing on here as some refer to the cover itself as the variator... So alleyoop is today's prize winner.  So it could be the upper chain guide bolt...  |

[replyingto=alleyoop]alleyoop[/replyingto]That may be it. I had to remove it to put a new seal on the back of the fastener. It did make me worry a bit not knowing what it was attached to inside the engine. It seemed to go through a rubber block inside the engine and threaded into something behind it. Well it must be OK because she went back on the road and did not act up!

[replyingto=alleyoop]alleyoop[/replyingto]I am glad it did not drop out of place when I pulled the bolt out! The funny part of this story is; I have had a very small (2 drips) oil leak since the bike was new. I never looked for it because it was so small. This was the problem all along. If i had not pulled in behind my wife and noticed the rear tire all slicked up with about 1/2 quart of oil on a 20 mile ride that engine might have been hurting. Thanks for the info and photo.
