Help Me Find A Pulley

[HawkinsHollow]

I am trying to convert an old makita that I don't use anymore into a debarking tool. The kit I bought comes with pulleys for Stihl and Husky. I was hoping one of them would work with the Makita, Doesn't seem like they will. So I need to find a pulley that will work. I figure if I use my digital caliper to find the diameter of the post on the makita I can find something that will work. I am here to ask if anyone know a source for such a thing. If does not have to be very elaborate. The included pulleys are quite simple. Once has a bearing in it the other does not. Suggetions? Tips? Warnings? HELP!

When looking for weird stuff I frequently start with eBay. If the shaft on your Makita is too small perhaps you could get a sleeve to go between it and the pulley. Of course if it's too large you could simply drill the center of the pulley to fit.

I'm confused about the bearing. Aren't those pulleys driven by the shaft? Is the Makita shaft too large or too small? It it's too large, perhaps you could get one of the pulleys machined to fit?

Simple fix for someone with machine tools.

The pulley is half of the centrifugal clutch that is probably proprietary to your saw, or at least very niche. What I'd do is keep the original sprocket hub, grind down the teeth so you can position a pulley off an alternator or other similar diameter that is drilled out to fit. Position it where the belt tracks and weld in place.

Go with a Stihl or Husky power head. Sell the Makita.

If it's a clutch plus a pulley then I would agree with zz - it's probably easier to get a different power head.

If it's just a pulley, try McMaster Carr. They have a remarkable inventory of stuff, all high quality, and with good drawings so you can really see what you are buying.

The maikta is not worth much for resale. Has no chain brake, hard to get parts for, etc. But it runs like a top which is why I want to salvage it for this project. Read: trying not to buy a new saw when this one is perfectly capable. One pulley it too small the other one is too big. And because of the round shroud they won't go far enough onto the shaft for a nut anyways. I suppose I could cut the shroud off and find a bushing that would make the diameters work. But thought it might just be easier to get a pulley that goes on there. Will check out McMaster and Carr on similar. Time to get the calipers out.

Is that bearing in there the style like an pto over running clutch. I have seen some of them used on machinery back in my before retirement days.
If you you put your finger in there and the pulley turns one way easily but the other grabs at your finger it is.
If so I would expect to see it free wheel clockwise but engage counter clockwise.

Great question. I will have to check that. But yes one of the new pulleys has that type of bearing and the makita has a similar bearing under the clutch housing, just bigger.
