Tight countershaft
yeomans:
It would be different if I took the engine apart originally, but this engine was all in parts when I first received it, and I haven't found any shims.
tobys 2 strokes:
If you were missing a shim that was needed it would be losser not tighter its probably your out put bearing not seated all the way.
I had that happen on my 97 that I have in me T4. but I had done a bunch of welding repairs to the cases and had to lap them to the point that it tightened the clearance up and had to remove some from that steel bushing in the cases to make it spin.
yeomans:
I had re seated the bearing last night just to take that off the list of possibilities.
But it was still tight when I re sealed the cases.
I had noticed a few very light scrape marks on the inside of the right case where the countershaft sits which made me wonder if it was a shim that was missing.
I do hear what your saying though about the case being loose if I was missing the shim
Rick james:
I had the same problem reassembling the cases on my 93. Tried it 4or 5 times, and as soon as I tighten the bolts, it locks up as well. I'm confident that I put it back together with all of the parts, as I'm using a service manual, and I took it apart extremely carefully, noting positions of everything. I even tried freezing the crank with dry ice, it dropped right in and was still frosty after an hour of sitting in the cases. Been waiting for some $$ to come through to get it done professiknally, but I've been hoping someone on here knows what it is. Good luck, let me know if you figure it out!
Motorrad:
Mix up the shift fork shafts??
Is the primary side assembled yet?
