The wide belt is not coming up to speed. It behaves as if a 'startup' issue.
Note it is a 7.5hp three phase running on a Phoenix rotary phase converter. It has always spiked amps at startup but the settles once up to speed.
But now it does not make it to speed. The feed motor works (at least unloaded it does). And if I take the belt off the main motor jumps right to speed. So appears to be load related.
Am doing the usual internet search, but posting here because a wealth of knowledge and if ever sorted out the post helps others someday.
This is a 'jet 16/32 widebelt' - I believe identical to a powermatic of similar brand.
It requires air supply for the tracking system, but I also noticed this pneumatic cylinder attached to a lever on the motor itself. Wonder if that is a cap start mechanism that needs to engage.... appears to be missing the linkage bolt. (note from what I can tell the cylinder is not moving at startup so this is part of the research to figure out purpose of)

edit: a quick search suggests this pnematic lever is a motor brake. Do not believe it has ever worked in the time I have owned it, given the slowness in winding down when shut off
