Topic tags/keywords: band saw motor pulley pulley replacement spare parts

I am trying to get to work my neighbor’s bandsaw which hasn’t been in use for about 10 years. I went through the manual, changed the blade and adjusted the tension, the guards and such things. The saw worked reasonably well for a few minutes until it started to vibrate with quite a noise and shaking.

This is why:

One side of the motor pulley almost completely crumbled!

Was wondering if this was just because of the saw age or I missed something in my check-up, like motor belt tension or pulley position? And what is a good resource for band saw parts?
This is a Jet JBS-14:

Also, is this the correct orientation of the plastic blade cover at the back of the saw, like here?

Would appreciate any suggestion or comment! Thanks and best wishes, h.

Probably just from age/abuse. You can get a new one any number of places… McMaster Carr, Grainger, MSC, Tractor Supply, Ace Hardware, etc…

Also, is this the correct orientation of the plastic blade cover at the back of the saw, like here?

Looks like it’s on backwards to me… the opening should face forward, as otherwise changing blades will be a royal PITA and you will have to remove the guard each time you do.

The guard on my old Ridgid is like that and has to be removed to change blades. And no other way to modify or install it.

How is it attached? Are you sure you can’t flip it around/upside down? I’ve never seen one that required removal for a blade change by design… but I have seem them like that when the guard was installed improperly. It’s very easy to do (flip around the wrong way) on the stock 14” Delta clone type machines.

Brad, Mine is held on with screws on the left hand, front side of my old gray Ridgid. I have not found a way to mount it where the blade can be changed with it on there. PITA but I don’t like looking at that exposed blade running above the table.

I have found the guard fits okay both ways and, when changing the blade, once the wheel covers are removed the guard is just pulled out, no extra fasteners to be removed or anything.

If I put the guard as in the photo, the blade doesn’t rub it at all.

What are good online stores for replacement parts like this one? Looks like Jet discontinued the original pulley.

The sources I gave above all should have a suitable replacement.. it’s just a pulley… nothing special or “Jet” about it. Just measure the outside diameter and bore size and find one the same size.

Cheers,
Brad

PS: It’s never a good idea to buy replacement parts from the manufacturer that are standard hardware store items. I’ve seen $0.10 bolts being sold for over $10 just because it was ‘branded’ with the manufacturers packaging. Cheap Chinese bearings being sold for over $30 by the manufacturer, where quality ones can be had from a bearing supplier for $4. You get the idea :)

Ended up ordering the motor pulley, or sheave, on the internet for about five dollars. After I’d brought the broken part to several retail stores and been shown clothesline pulleys as an option I went straight to Amazon for exact replacement. Thanks Brad and gvfadvm for the suggestions and comments.
