Does anyone have a main input shaft or coupler for a B&M 420 Blower, I need 2 sets?
I sent my B&M 420 blowers to The Blower Shop to get rebuilt, long story short I was running on borrowed time. The main shaft and coupler are shot. TBS was surprised the snout didn't break off they are that bad, normally the can weld and grind to repair them but mine are too far gone. These parts haven't been built in a long time. I could switch the snout to a TBS but then I have to change all the pulleys, dampners plus rebuild the blowers; TBS said it almost just as cost effective to by new complete 8-71's, so that's not really an option.
