Do you adjust band saw blade center without it running?

I just replaced my drive belt on a Craftsman 12" Band Saw 119.224000 and I was having trouble loosing up the blade tension. So thought if I moved the center adjustment it would loosen up, but that was a mistake. Now I have to readjust the blade center and wondered if it could be done without it running. I just want it to be in the ballpark for the initial adjustment so it don't jump out at me.

(I assume that you are referring to how the bandsaw blade tracks on top of the upper wheel tire because you said, "...so it don't jump out at me.")

The answer is yes. In fact, I always adjust the blade tracking with the bandsaw unplugged.

I spin the wheel with my finger and adjust the tracking screw on the back of the wheel until the gullets of the blade are roughly in the center of the top wheel's tire. The idea is to support the body of the blade well, but leave the offset teeth barely out so that they don't cut into the tire.

Yes that's exactly what I'm talking about. I couldn't find anything on YouTube, but I was only looking for my Craftsman saw. I Haven't done it in years and was confused by centering my belt sander.

I do have one other question on the drive belt. The old belt just disintegrated and I don't remember which of the 2 pulleys it was set on.

Owner's manual? www.ereplacementparts.com has schematics that might help. Just need model number of the item.

A diamond is how coal reacts under pressure.

I downloaded the manual for this model band saw from Sears Parts and it's like a copy of a copy of a copy. I can barely read it so I went to another place that had manuals and it was the same thing.

The larger pulley on the motor and the smaller pulley on the wheel will give you the fastest speed which is what you want for wood. I just replaced the belt on my 10" Craftsman saw and it was easy. The lower wheel comes off with a circ clip, then slip on the belt, replace the wheel and clip and tighten it up.

I got adjusted and it seem to be cutting alright, but there is a noise in the top pulley compartment that sounds like aluminum rubbing against aluminum. I thought the pulley was touching the aluminum guide, but I can't see anything.

I have fairly new tires and they don't look worn although they have a lot of sawdust stuck to them. Do you think that might be causing the noise? I'm going to try to clean them, but it really sounds like aluminum scraping aluminum

Lower the upper blade guard .....

Spin the wheels by hand with the blade guard all the way down. That's a typical cause of the rubbing sound. The wheel is rubbing on the blade guard when it's all the way up. Just readjust it. Do NOT operate it with the rubbing sound until you figure it out!
