Drive side crankshaft seal

Disregard, just found it!

make sure it is from the crank seal and not from the gearbox this is where it usually comes from,if you are going to change the crankshaft seal make sure you use a decent puller to get the pulley off and make sure there is an 8 thou air gap between the rotor and stator when you replace them ............nick

Thanks for the tips, I'll check the gearbox seal as well.

the oil comes along the clutch pushrod from the gearbox to the clutch ,if it is doing this you can fit an oil seal conversion on the end of the output shaft inside the clutch ...........regards nick

Thanks, nice to have a solution for that scenario as well!

For what it is now worth, and maybe just a bit of belt and bracers, Steve Maney Racing do a drive side oil seal that is not expensive and supposedly better than standard, as it was designed to overcome the leaking problem when running a belt drive. If the option is allowing to fit one it might be a good idea. They can be bought through his website

My newly acquired 1972 Commando Roadster MkIV is still uncharted territory for me,so my learning curve is still pretty steep.

First niggling littleproblem is a slight seapage of oil into the primary chaincase. Now, I don't want any oil in there, since my Commando has been converted to belt drive. I assume oil is seeping through the crankshaft seal,if there is one. Having looked at the Tech section on this site, I can't findany mention of a seal on the drive side, whereas the timing side seal is mentioned.

Can anybody confirme that there is a seal, what kind of seal, and if it can be replaced from the outside, that is without splitting the crankcases?

Thanks, I'll check that out once I have established whether it is indeed the drive side oil seal or the gearbox pushrod.
