Kickstart shaft end thrust

So, my gearset was pretty worn and it looks like one of the shafts was bent a little.

So I got new shafts and a new gearset. Both were old stock, but as new.

I'd had excessive end thrust since changing the layshaft roller bearing last year. I checked it after assembly and seem to have about .080" of end thrust on the kickstart shaft. Just curious if anybody has ever seen this.

I assembled using a gasket between the inner cover and main case. Torqued the nuts to about 18 pounds.

Also found the steel kickstart shaft bush in the inner case spins in its bore. Problem?

I have .080" with of shims so I should be able to get it in the ballpark. Wondering what folks have seen and if this sounds odd at all.

Any advice is appreciated.

That much endplay is not uncommon, roller or ball bearing doesn't make any difference. You will want to reduce the endplay with shims to around .015 inch or you may have problems with the trans wanting to jump out of first gear. Jim

I ran out of gaskets in Ms Peel drive train trauma lesions so asked what need of them from 3 different lists and told there is no need of em and found it takes care of the shim issue w/o any shims. Just don't use goop that also a glue or next time in or next fella in will not think nice of yourself or you. Please correct me if I'm mus-guilded or not.

Thanks for the help. I do have the shims to do it, although I found that they were hanging up on the radius at the base of the kickstart shaft, so I was increasing the ID in my spare time...

Glad to know .080" isn't uncommon. Because I seem prone to uncommon problems. Hope the rest of assembly goes smoothly.

The gearset looks really nice, like it was barely ever run. It was somebody's pet project they were waiting to install in the right bike, but never got the right bike. The gears are plated with some kind of industrial chrome, it looks like. Has anybody heard of that?! Shaft and bush fit, and condition, is all really great. Unusual, I thought, to see them plated, but considering the face pitting on my 15,000 mile box, I can see why you might want to try something like that to control wear.

Was surprised to find the bent layshaft in my original box. Low miles, really, and I have always been pretty friendly to the bike.

I have bought a couple new and obviously never used shafts that I had to send back because they were not straight. Yours may have been that way since it was new. Jim

Played with the shims and got the inner cover back on. All it good. Looks like it's about .012" on the kickstart. The gasket was right around .020" but crushed a bit more than that once it was in place and the nuts were torqued. Primary yet to go for reassembly. Thanks for the help.
