Oily Left Foot (crankshaft seal)
Posted: Sat Oct 10, 2020 10:42 am
After a complete engine rebuild (with new seals, gaskets, etc etc), I still had a slow drip from the left side crankshaft seal - the one under the ignition timing sensor plate. The guy who installed my Yamaha seal (me) managed to get the little spring and inner lip of the seal a bit folded into each other. (No photo of that, but maybe you can imagine.)
So I replaced it with a KTM part number that my preferred supplier had in stock. A very nice seal (but I didn't take a photo of it, either.)
KTM crankshaft seal (same size as ours) It's still leaking.
I suspect I'm doing something wrong.
How deep is that seal supposed to sit?
Flush with the engine case surface? Fully seated?
Should I be using a gasket sealer on the outside surface of that seal?
Thanks in advance
