Topic: Oil Leak Locations

[Boogerbandit04]

Battery problem fixed, just not enough riding above the right RPM. I now noticed I am leaking oil from what looks like where the gear shift lever meets the side of the engine. Is there an oil seal there that could have gone bad? There is also oil along the cooling fins, O-Ring?

Yes.

O-rings....they all do that, mate! Live with it or take the top end off and replace them.

It's the shift shaft seal.  Takes about 5 min. to replace. Instructions on numerous threads.

Shift seal eh? Im looking on Honda parts direct, is part #22 the right seal? Im just  wondering. Im still new to all this stuff, I have a repair and maintanince manual but its not very clear.

91202-KFL-841 is the part no. for a CB550 (1976). Probably the same part for other years.  I could not get you link to open the schmatic, but it is part no 22 in the "gearshift drum" schematic.

Easy change out for you.  You will be glad you did it too.

How much of a booger is it to change the Tach drive seal. It appears I am springing a minor leak. I am at the wipe it off mode right now, but I am sure it will not cure itself.

Hey right Bobby...those don't cure on their own.   Seriously, it is an easy fix for you.  I saw a thread on Tips and Tricks that might help you out too.  Heck, the seal is like a dime with a hole in it.  If you use the screw method, do not drive that screw between the center hole of the seal and the shaft or you will score the shaft and have a leak forever.  Some guys drive the small screw right into the seal and pull it out.  For ease of putting it back in, I use a dummy tach housing (see pic) and push it right back in.
