O ring for 4 speed trans
« on: June 15, 2017, 11:23:11 AM »
I recall quite a few years ago Harley came out with a replacement gear or shaft that had an "O" ring built into it to stop oil leaks in the 4 speed trans. Anyone know the part # for it??? Thanks, Frank

     I'm not sure that it was Harley, pretty sure that it was an innovative individual who happened to be a machinist. The O-ring is located in the main drive gear spacer. There are atleast three different main drive gear spacers depending on the year of the tranny. HTT member saddlebagrail makes them so send him a PM and he should be able to hook you up. If you Google "Harley 4-speed main drive gear spacer" and scroll down a bit you will find saddlegagrail's PDF.  I'm not sure that it's w/in HTT policy for me to post a link here so I won't. Bill

Used his specs to have my spacer machined. Great fix. Had to buy like 10 o-rings to get one, so if you need one, pm me and I'll send you a couple.

Thanks for the info! Mike, do you have a copy of the spec for the machine work? I have a friend who could do it when I take it apart. Thanks, Frank

Not a problem.  Ray's spacer has been discussed on HTT before.

Finally a cure for leaking 4 speed tranny
