view you should see a soft metal pin/rivet/stop which is the over-engagement
stop. This is likely to be considerably worn.
Me: There is no stop pin/rivet at all, nor never was there. I understand what
you are referring to, probably added on later boxes to correct the fault I am
now experiencing.

spacer (washer) at the back of the case to keep first gear from moving along
the mainshaft too far. It's crude but effective. A friend has done it to the
Moss box in his 1951 Morgan. No more trouble. Of course it requires removing
and dismantling the box to install the spacer, whose thickness will have to be
determined. I think it was in the .100" range.

Me: I have discovered a spacer/washer on the 1st/2nd fork actuator rod that
isn't in the parts list. It has the effect of reducing the rearward travel of
the fork into 1st. Also, the locking wire on the setscrew for the 1st/2nd fork
is a different color than all the others. Aha! Some PO has been messing with
the fork, maybe to fix the same problem. Now to figure out what he did, he must
have added the washer, maybe he replaced some parts with newer parts? Stay
tuned. Rob
