Yamabond work well on cases, and red LockTite has always worked well for me on the motor sprocket shaft nut....bosheff

I haven't purchased Yamabond in many years. I always got it at the Yumyum shop. You can always send the ol lady or kid in to git it if ya don't want to be seen coming outta there, or wear a mask....bosheff

The real name of the stuff is Three Bond Liquid Gasket 1194. Yamaha only puts their name on it. I just Google it and buy on line. Much cheaper and you don’t have to worry about the club working you over. This is the best stuff made. Been using it for 25 years now and my pans don’t leak. Bob L

Heat? What in hell do think they invented the impact wrench for. I run my air in the shop at 175 psi. no problems.

JR,
I never put anything on the bearing retaining nut, just screw it in tight. There is no shock load on it and unless your engine seizes the bearings while running backwards it isn't going to unscrew! Never had one loosen at all. It bears against the inner race/spacer stack and there should be zero movement there. Once it is seated tightly it remains so.

If I may add some notes:
The Factory staked the retaining nut, so a threadlocking goober would be indicated.

Second note: A nut with a seal in it would be aftermarket, so inspect everything very closely!

Third note: I found Yamabond 4 to have about a six year life expectancy on motor cases in hard duty. I then switched to 3M Industrial Adhesive, which carries a -80 OEM number.
Yamabond was always a lot prettier.

No doubt there is probably a "harley-bond" by now?

(I love Gasgacinch too, but for other things.
If your cases were absolutely square and unblemished, a silk thread held in place with Gasgacinch would be a premium treatment, but who has virgin cases? Nevermind.)

I had a virgin case once....my best friends older sister helped me out with it....we didn't use any locktite....Just a little lubrication before assembly. Sure made for a real sweet ride. Had nice bottom end and a good pair of spot lights on the front end. Man those were the days :wink:

I have and it's not good. Destroyed an early knuckle case. It will allow the tranny to go into 2 gears at the same time. But it should not come loose if you bend over the tab to lock the nut. Lesson learned the hard way.
