Apologies if this has been covered before, but I haven’t been able to find anything. A friend purchased a Delta 36 630 Contractors saw and while helping him tune it, I found quite a bit of slop between the trunnions and the arbor assembly. The blade sits parallel with the insert slot when the belt has been removed, but skews dramatically to the front right edge of the slot when the belt (and the weight of the motor) are replaced. And I can easily shift the arbor assembly with hand pressure when the belt is removed. Both front and back trunnions appear to be securely fastened to the top – but the arbor assembly doesn’t appear to be seating properly in the trunnion slots.
My initial thought is to adjust one trunnion toward the other to press the arbor assembly deeper into the the trunnion slots. But I can’t tell if it’s only an adjustment that is required or if the slop is the result of wear to the trunnions, arbor assembly or both. And the kicker is… replacement trunnions are no lounger available for this saw.
So I thought I would check to see if anyone has come across this… Any tips on adjusting the trunnions? Any ideas about solutions if it turns out the parts are worn? The only thing I’ve been able to come up with is perhaps some kind of rope gasket (similar to the rear main seal on a crankshaft) to take up some of the play in the slot.
Normally I would attempt a repair before asking for advise. In this case, depending on what I find, I’d like to understand any options so I can advise my friend.
Thanks in advance.
