Help!!!!!!!!!!!!

I just replaced my 4th and 5th gear sychro. Disassemble we easy just like the manual says. Replaced the thrust washer and retaining ring.

Now the problem the 14 rollers that go into the fouth gear. I have tried greasing them to the shaft, tried installing the main shaft then greasing them to the bearing surface but I still can't get the shaft seated without losing one or two rollers.

What am I missing it can not be this hard.

Help.

....just a little bit more patience and some synthetic grease (more tacky) if available.

The rollers have to be "glued" into the input shaft, first. If they are not excessively worn they will hold each other in place (only can slide out).

Try again, it IS doable and has been done x-many times!

So not on the main shaft but inside the input shaft correct?

Yes, and I used GAA grease and had no trouble at all. Find some thick grease!

Thanks for the help. mainshaft in but now when I let out the clutch I have a grinding sound. Did not have it before, I am thinking I have the rear shaft nut to tight????? Everything spins.

Or I must have over looked something. I was able to shift into 5th gear but it locked up?

Help

Sounds like you did not install the shift forks properly. Remove the trans top cover and carefully set the gears in neutral, then carefully set the top on and confirm it feels right and the forks are engaged in the slots.

The rear bearing retainer is shimmed to set the shaft free play. Not the nut.

thanks, that would solve my lockup problem but the whining or grinding noise I hear with the top cover off when I let out the clutch. I did not notice this noise before.

If you have no free play on that shaft, it might make the front or rear or intermediate(seperate rollers) bearings make noise. Be extreemly careful running it with the cover off, it could pull your clothing or hair into the gears in a second. I assume you put oil in it?

Thats what I thought, when I tighten the shaft nut it seemed that the hole for the cotter pin was to far away from the nut.

Thanks for the help

Here's a thought, not sure what it will prove but, you could engage 4th gear and the input and output shafts will be turning the same speed. You might be able to tell if it's the intermediate bearing making the noise.
