1978 GL1000 Final Drive Leak

Postby TheRobbie1950 » Mon Mar 16, 2015 9:12 am



I have some oil leaking from around the final drive on my 1978 GL1000.
Is it a huge task to put a kit into it to stop the leaks, or should I leave it to a pro?
I am planning a long trip this summer, so I want to have it in decent shape.

There's no "kit" to install if by that you mean a quick and easy fix. Fixing a leaking final drive involves replacing worn out seals. This involves disassembling and reassembling the unit, which involves setting driveline lash - which can be quite complex and involves some specialized measuring equipment.

If the leak isn't horrific, many people have had very good luck with Lucas Hub Oil in their GL1000's:



You may find it seals up your leaks and gets you through without a rebuild.

Yes WingAdmin, actually that is what I have found out so far and will be doing that.

Thanks for your input.

A replacement from a used source is often the best method. My leaker did not stop leaking with Lucas, but I agree it is worth a try. Be sure to not overfill the drive, as that certainly makes a leak more likely.

Thanks Fred, replacing it will be a last resort................the bike only has 55k on it.
