new superhawk... with issues

[JRT68]

Yet another newbie, just brought home a sweet '67 CB77 that looks/runs good, but my initial excitement is being frustrated by stripped out teeth on the shifter spindle. For a band-aid, I slipped a shim from an aluminum can on the shaft but the teeth are so far gone that it wasn't long before the lever was slipping again. Anybody have any repair suggestions that don't involve opening the case to replace the spindle?

You might consider drilling a hole between the two and putting a screw or bolt between them and you may have to do opposite sides. Just remember if it does not work you be back to square one, with very few options.

Well, after cleaning up the splines a bit and fabricating a better sleeve from shim stock, the shifter seems to be firm (for now). The new concern is charging- or lack thereof- so I'm looking over the posts related to that and checking components. Gotta love old machines!

Please never mind my offer. ...............LM

LM,

Thanks just the same, I'm sure I'll need one before too much longer & will hit you up then.

I'd be inclined to take up Ed's offer before he sells out; these shafts are as rare as unicorn poo. Get a shift pointer/lever too; if the splines are damaged on one component, then they'll sure as hell have transferred the damage to the other. If you don't replace both, you'll end up re-transferring the damage from the old lever to the new shift shaft!

As an interim measure:

• remove the left footrest ass'y & detach the shift pointer/lever from the linkage;
  set the pointer on the damaged shaft, pointing towards 11 o'clock position and clamp up tight the lever on the shaft with no shim stock in place -- the linkage to the pedal, when at its rest position, should be +/- perpendicular to the pointer's bisector and parallel with the pinch bolt;
  drill 2 x 3.5mm holes, diametrically opposite one another and in line with the pinch bolt's parallel, into the mating circumference between the lever and the shaft to a depth of 12mm and no more (or you could end up damaging the seal);
  tap these drillings with an M4 thread and install 2 x M4X10mm machine screws -- Allen-head grub screws work best, as they're generally hardened.

It won't look great, but it will mean the difference between a tear-down now or a tear-down later, with planning.
