Oil Leak

Is there suppose to be oil in the left side cover where the pulsar
coils are or should it be dry? The motorcycle is a 81 CB750C and was
wondering if it should be there or do i have a oil seal leak?
Thanks,L.Watters

 

Try using your center stand

 

Ok? I'm gathering it should not be there then..
Thanks

 

The starter clutch idler gear desperately needs that oil from the
crankshaft to lubricate the bronze bushing.

Go to www.partsfish.com and or www.bikebandit.com and look at the
STARTER diagram. Item # 3 is the idler gear, and you can see the
bronze bushing in the center of it. The bushing looks like it has
spots. Those are oil retaining cavities.

When you are riding down the highway at 100 mph, just think about that
idler gear, sitting motionless on the crankshaft while the crank spins
at 7000 RPM inside the bushing...

Scary thought: what happens if that bronze bushing seizes onto the
crankshaft.

You'd better hope that bushing gets all the oiling it can stand.

 

In my experience it just melts, and the starter idler starts rattling
and making lots of noise.

Ok? one says yes? and one says no?

 

Yes, there should be oil in there....

 

In my experience, the idler gear flops around and contacts the
cylindrical rollers.

This locks up the starter clutch and backdrives the starter at a 10 to
1 ratio.

If you're riding at 4000 RPM, the starter suddenly has to turn 40,000
RPM which it cannot do.

The starter self destructs as copper windings are thrown out of the
laminations and
segments are torn off the commutator.

The rear wheel momentarily stops if the starter clutch unlocks.

If the starter clutch doesn't unlock, the rear wheel remains locked up
and the rider
falls

 

Thank you very much for your help,L.Watters
