Topic tags/keywords: bandsaw pulleys alignment

Hi Everyone,

I was messing around with my recently purchased used Powermatic 044 bandsaw and while setting the tracking and making small adjustments to the tracking knob while spinning the wheels by hand the belt popped off of the pulleys. I put it back on and tried it again and it happened again. I took a real good look at the alignmrnt of the motor pully and the wheel pulley and noticed they were about a 3/8” out of plumb from one another. Started checking the lower wheel alignment set screws and bolts and saw that it had been adjusted so that the top of the bearing plate was touching the housing but the bottom was away from the housing by about 3/32”. I started fresh and set the plate flush to the housing top and bottom which made the wheel pulley even more out of alignment with the motor pulley. At first I thought the shaft from the motor was too short or maybe the motor was mounted too far away from the housing but the holes all lined up with the motor mount and I didn’t really want to drill the mount and possibly screw it up even worse. I checked the motor pulley and the hole that the shaft goes through with the set screw was facing out so I took the pulley off, flipped it around and it aligned with the wheel pulley. Now the pulley set screw is behind the wheel but I can still get at it without taking off the wheel if I need to. Does anyone know if this is the right way to mount the motor pulley? The blade seems to track much better now, just about dead center on both tires. I just want to be sure this is ok.

As long as the set screw is firmly on the shaft, that’s fine. I had to do this with a Jet jointer a long time ago to get the pulleys aligned and that is still working just fine 20-some years later for the guy that bought it from me. I think this gets out of alignment when the motor, the top portion of the bandsaw and maybe the brackets are all aligned to their max the wrong way. Flipping the pulley is probably the easy way out and just as good.

Hi Todd,

The boxers name is Abby. She’s a great dog. She’s 6 years old and recently we got her a new playmate. An American Bulldog puppy. Her name is Sophie. Another beautiful dog. I’m going to have to update my profile picture and try to fit both of them in there.
