I’ve had an 18” grizzly band saw for about 25 years. The bearings have gotten pretty noisy and I want to replace them, I have no clue how to accomplish this task. I bought the replacement bearings and can imagine the type of tool to pull the old ones but I don’ really know how to go about this. So I have two questions you all may be able to answer for me; 1, what tool do I need to pull the old bearings ( pilot bearing, blinded bearing etc.) puller tool? 2, what tool do I need to press the new bearings back into the housing? Can I just use a block of wood and a hammer?
Any advice and recommendations will be appreciated.

A three jaw bearing puller set (multiple sizes) is nice to have, but not always required. Same deal with a bearing splitter. And in the hundreds of bearings I’ve replaced, I’ve only used a press once – and that was just because it was sitting in front of me at the moment; I could have easily gone without it. There are lots of way to go about it, and if you really need something, most auto parts stores will provide loaners these days. Give us a model number and post a few pictures if you need help.

Cheers,
Brad

Funny I have a Grizzly 14 inch BS for 4 year now and have used it very little but the bearings in/on both upper and lower guides I think are way to noisy.

Here’s a picture of one of the bearings, not sure if the noisy one is on the wheel or the case but I plan to replace them all four (upper and lower) while I have it apart

I’d go ahead ahead and replace the motor and guide bearings while you’re at it. Knock it all out at once.

All the three jaw bearing puller sets on Amazon look like they grab the outside edge of the bearing, Don’t I need to grab the inside???

No. You use the puller to get them off, so at that point it doesn’t matter what happens to the old bearings. As far as I know.

For the wheel in question, you don’t need a puller. They should just tap out with a pin punch, wooden dowel or whatever you have and a small hammer. For the lower wheel and motor, a puller/splitter may come in handy, but you can usually get them off without one. For the occasional use homeowner type stuff, a cheap set from HF works well – they have a set of three for under $20, and a set of four for under $30. Their splitter is also pretty decent, but you probably would never need it for what you are doing.

Cheers,
Brad
