Help Me Find A Pulley

[flyerdan]

I saw that kit on Amazon and Walmart while looking for a manual for it. I'm sure that somewhere in the docs it says to replace the sprocket clutch drum with the pulley one and keep the clutch. Otherwise you add to the rotating mass making it harder to start, plus you'll always have a live cutting edge going all the time, which would make all the safety nannies absolutely piss orange juice, and unless you run the belts really loose, if it binds somehow there will be no slip factor to either kill it or shock stop it.
Plus, without the centrifugal assembly, there is really no way to drive it with in the box stuff.

It says to remove the clutch in that first picture. But it does look like that drum is designed to sit down over the clutch. I do have a husky 142 I could put it on, but that is my backup saw for my bigger 60cc saw. So I haven't opened it up to see how the pulley works on the Husky as I had my heart set on using the makita. I guess I can turn the Makita into my backup saw.

I think the problem is what folks are calling the clutch. I always think of the clutch as the weights that grab the clutch drum, but the instructions are saying the clutch drum is the clutch. In any case you need the weights to remain so that they can grab the clutch drum. Hopefully you can find a needle bearing at McMaster-Carr. Realize that the clutch drum must be a pretty close fit to the weights. I suggest you measure the Makita clutch drum inside diameter and compare it to the one provided in the kit. They should be close. If the drum is smaller it will grab at a lower RPM and if larger it will grab at higher RPM. There are also log peelers that use a chain saw chain instead of a belt and these would work with your Makita. They do seem kinda dangerous but then a chain saw is kinda dangerous. And log peelers are kinda dangerous too. A friend of mine has one and it removes bark scary fast. I bet it removes flesh scary fast too. Some of the chain saw drive ones require two holes to be drilled in the bar and then you use a longer chain to drive them. But these would use your existing clutch.

This style mounts right on your Makita bar. No worries about drums or nuts.

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!View attachment 2410331

Grainger.com has an good selection of pulleys. isheaves.com will custom make any pulley.

My 2 Cents , you are going to spend more cobbling up a pulley/clutch assembly than a pawnshop powerhead. AND , the life expectancy of a homemade rig , spinning at 10K & held closely to your privates, won't be long. Looks like you bought a $79 amazon genuine chinesiam debarker, buy a matching knockoff powerhead from same and call it good. Those old Makita/Dolmar units run well , but are odd ducks.

Any machine shop should be able to modify those to fit
