As I switched from a Shovelhead to a Panhead motor, the belt
was hanging too far outside, so I decided to replace the mainshaft
and while I was at it the housing as well. In this installment
I am reassembling the transmission. All the tolerances have
been checked and corrected where necessary.
While aligning the shifter forks I found that the nut holding
the rear shifter fork ( for third and fourth gear) had come
loose and the fork had already been touching the main gear,
good thing I cought that because that could have caused a lot
When aligning shifter forks you want the main drive to be
in the correct position, as it is with a sprocket mounted and
the nut tightened. However with the sprocket in place you can't
get the shifter fork shaft out, so I made an aluminium spacer
to replace the sprocket. This saves some time when aligning
I found that the shifter forks were also Andrews, not bad!
After centering both shifter forks using small shims I could
reassemble the top and put the transmission back in the bike.
Now I can align the primary belt next, which will not stick
out so far anymore.
