Bottom End Assembly - Help Me Out Please!
Posted December 26, 2004 - 04:17 PM
When I assemble the cases and torque the bolts to spec, the shift drum locks up. If I loosen the bolts, it will spin freely. I think when I torque the bolts, it's drawing the case surface into contact with the end of the shift drum, preventing it from rotating easily.
I have a parts breakdown and all pieces seem to be in their place. When I manually run through the gears (before case assembly) it shifts smoothly through every gear.
Is it common to require two base gaskets when reassembling? I'm sure another gasket will do the trick to offer more clearance for the drum, but maybe I'm looking past something.
If you can, please help me (and the little guy) out.

We also had a problem with the inner drum (the piece that you have to remove to get the bearing off of the shifter drum). It wasn't fully seated, so when we put the rest of the shift mechanism together, the roller was pressing hard against the side of the inner drum and wouldn't let anything turn.
That's what happens when you wait morae than a day or two to put the thing back together...you kinda forget the details. (This one was apart for a month while we shipped the cylinder off to Eric Gorr for a big bore kit)
As a sort of solution, I'v started to document disassembly, orientation f parts etc. of a project with a cheap digital camera that I picked up at Pep Boys for $39.00. I have an old K6-450 PC hooked up in the garage to play MP3's, connect to Thumpertalk and the YoT websites, and view those pictures. It' really saved my ass in putting the wife's minivan motor back together and getting all the emissions and electrical connections right!
