I've been slowly reassembling my 3-main engine, and had a question
about the proper tolerances/installation method of the crank timing
gear.
Since I'm using a reground not-quite-stock Elgin cam, I thought I'd
get an adjustable gear set. Got the indexed Australian-made set from
Moss (too cheap to buy the Kent vernier gear set.)
In assembling it, the gear took a lot of force (blows with a copper
hammer) to drive it onto the end of the crank (and pull off with a
3-arm puller.) FWIW, the crank has been nitrided, and I smoothed off
the end of the shaft with fine wet/dry paper and oiled it prior to
installation.
I'm wondering how much force this should take. Do I have a problem
with part tolerances? Has anyone else tried this gear set? I could
probably heat the gear up prior to installation, but removal would
still be problematic.
Thanks,
Chris
