I just found out today that if something you bought from Harbor Freight broke them most likely you can buy a replacement part for it. They have a list you can download and look through and find the part you need and can call and order it. Here is the list:
I had bought a metal cutting bandsaw from HF, and it worked fine. After about 2 years, one of the bearings failed, and I contacted HF for the repair part listed in the parts list which came with the tool. Soon after I requested the part(s), HF notified me they couldn’t get the bearing and told me to contact Grizzly Tools to get it and the parts. So unfortunately, they don’t always have the parts you may need! After the fact, I also found a local store where you can buy bearings in any size, expensive based on shipping, but at least they have any size you need.
I should add I also have bought several tools from Lowe’s, with the Kobalt brand name, and I couldn’t even get or order replacement blades from them and they suggested the manufacturer of the saws - they said no also. It isn’t just a HF problem, but does show if you use your tools, you might be better off buying a better known name brand to ensure you can repair them if needed.
