I continue on my journey to restore my Comet to (hopefully) pristine condition.
Some while back I rebuilt the Burman gearbox, replacing all the bearing, bushes and all of the spring box components. I am running it with Penrite Semi-Liquid grease but am plagued with a oil (or should that be grease) leak from around the gear-change lever shaft. After every run there is a generous smudge of grease on the gearbox cover with some making its way onto - and thus staining - the exhaust.
I now am in the habit of carrying an old rag and every time I stop its a quick wipe of the gearbox cover to try keeping the grease under control.
For what its worth I have installed a felt washer (home made) between the gearbox case and the gear change lever [as I have also done with the kick start lever]. Also I have put a 1/16" vent hole in the gearbox cover cap - the bit that goes over the clutch lever - in an attempt to relieve any internal pressure - but all to no avail; however there are no leaks from around the kick starter or from the new breather hole.
Question - is my experience common? And - what can be done to try to eliminate the grease weep from the gear change shaft?
