If it shifted OK before, no need to reshim the shafts.

I repaired one just like you describe (hole punched through case) last
fall. Just tighten everything well, and it should work if it was
working. In your case, the nut on the aft end of the shaft may also
have been loose, causing the crunchy shifting. Take out the output
shaft and make damn sure you have the front, ccw tightening, nut fully
seated. Use red loctite on it and punch it thoroughly to prevent
loosening. Then shim the drum.

The long story as short as possible - last spring I bought my '74 disc
Eldo Police and after a few miles the forward layshaft nut chewed
through the tranny case (last year). I tried the quick fix - attaching
a new nut through the chewed hole and sealing the hole up with scrap
aluminum and JB Weld - and the tranny made godawful noises when
shifting up from first as it transitioned neutral - so I put it away.

Just getting around to starting the project now - so, using Pete
Ropers DIY article from guzzitech on shimming as a reference I pulled
the tranny apart today - and it all looks brand spanking new. Nothing
broken, no metal bits. The input shaft is not coming out, even after a
few taps. Before I go wailing on it, I thought I'd check to see if
there's something I missed - it feels like its still "locked" in place
- I removed the nut, tang washer and Boss. Also interesting, I only
found one hardened washer under the pegnut on the speedo, not under
the drive itself?

If anyone has any hints on what to look for, and reshimming the 3
shafts (not just the drum), certainly appreciated.

Thanks, -tom
