Leaked a bit of engine oil

The countershaft sprocket leak is common on these bikes, including mine. Andy at HVA-factory came up with this solution that seals it without bearing replacement. But shipping from UK is steep for us in the USA. You can find them on HVA-factory.com if interested.

A bit like this then ...

This is the first prototype! I have ordered some seals to fit between the 30 diameter of the sleeve and the bore of the cover plate. The O-ring sits in the small recess and against the bearing to stop the leak....

except Harleys...

Or British bikes.......

That's awesome. Thanks for the assist.

I have a 96 Land Rover so I'm used to leaks, but I don't like them.

I tend to leak a bit from time to time...

if there isnt any oil under an old harley, there isnt any oil in it.

Consider it a visual aid.

I always wanted to restore an older Harley to test the new silicones of today to stop leakages. Just to prove it's possible. Even the older early 1900's bikes get my heart pumping.

When I worked for AMC JEEP as a mechanic the customer asked me if all the leakage under his new CJ 5 was normal. The head mechanic ran over and called it running seapage before I could say the truth. For the rest of the time I worked there the new buzz word was, "running seapage". Again oil leaks are unacceptable.

There's no seal on the four bolt bracket to the sleeve. I just silicone the bracket to the case, then silicone the splines on the sleeve.

I had a oil leak on a Suzuki TS 185 test me. I put in a new shifter shaft seal and she still leaked. I found a burr from a pair of vise grips or pliers on the shaft. Every time a new seal was installed the burr cut the seal. After some filing problem solved.
