Just curious if anyone has encountered a similar situation. Cheap tool and silly question, so don’t read on unless you’re as cheap an/or curious as I am.

My cheapo Harbor Freight electric chainsaw crapped out. When I took it apart, I found the motor shaft driving a sprocket, which links with a plastic gear of sorts. Of course, the plastic gear is stripped to all hell. The saw is about 4 months old—old enough that I can’t take it back but lots of life left in the bar, chain and motor. I would really like to just replace this part.

2 questions:

1) Has anyone replaced this part, or one like it before? What’s it called? Do you know of any chainsaw parts suppliers? I have the regular Ace, Lowes and so forth around me. I imagine this would be a mail order for me.

2) The bearing on the front is really friggin hard to get off, and I would need to do that to replace the worn gear. How the heck do I get it off?! I think I need a microscopic 3 jaw puller! :-D

I’ll try to keep this thread updated for future reference. in the meantime, feel free to chime in!

thanks

Usually HF tools come with a manual that describe the parts. If you don’t have it, you can get in online and order the part from them. Be ready to wait several weeks and e-mails saying it had to be reordered. Just keep telling them to go ahead and re-order. Some parts will ship directly from China.

I believe the part is called sprocket shaft.

That’s cheap chain saws. It’s really a tool where
investing more is worth it. I have a Craftsman now
and it works well. I had a used, older one for awhile
when I lived in the Northeast. It was heavy and ugly
but it worked well and cost us only about $50.

What you need to pull that bearing is called a bearing splitter. You might be able to rent one from an auto parts store or a friend that is a mechanic. It works with a regular 2 jaw puller, otherwise you run the risk of ruining the bearing trying to get it off the shaft. I would offer to loan you mine but NY is in way far East Texas and the gas would be more than the tool.

It looks like all the cheapo saws under 100 bucks (Remington, Poulan) use that plastic gear, from what I gather searching for parts.

Thanks for the tip on that tool name. I do think spending more is worth the investment, now that I use it so much for wood turning. Without this tool, I’m suddenly stopped in my tracks. I’ll be damned If I start splitting logs with a hand saw or 250 hammer blows!

Golly…but maybe someone will find this thread and avoid the low-end electric saws, unlike me!
