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.

Have a look

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

I believe the Makita saws are made by Dolmar. You might try their parts system.

Would it not be simpler to return the one you purchased and get one compatible with your makita? Also I saw on Amazon, a chain driven model that was like $70 where you only have to get a chain that is 2 inches longer than yours.
Looking for that special pulley might take you a long time...

 

[Bentrim]

Makita and Dolmar made cut off saws that use a V belt to drive the cutting disc. You might be able to find one of those pulleys online. Many of those saws had little maintenence and died early, but the pulley would be reuseable. but note those pulleys are clutch driven. Maybe you can pick up a used saw on marketplace or E bay.

I have found one that is Makita specific, but I have not found a source for it here in the states. I will keep looking for that, they are bound to be here. If I can't find the one O need I might have to go the log wizard route, but I want to find a chain without teeth. That seems extra scetchy. They make those right?

Great idea.

Look at the old clutch *drum* (agreed, bad nomenclature in those instructions) and see what the measurements you need are. Reinstall that old clutch drum and set a straight edge alongside the drum extending out to the debarker pulley. Check the offset you need to the pulley groove that way. It's a rubber belt, it doesn't need to be within a few thousandths of an inch. 1/32" will do fine. Likely even 1/16" won't *kill* you. Look to the old clutch drum for your bearing and ID requirements also.

 

[eddieirvine]

If you can figure out what you need and what pulley you are going to use i can bore out the pulley or make bore one out to fit with a sleeve pressed in

Just take a well used chain and grind it down will probable be easier.

Well none of my chains are long enough, so I have to buy a new one anyways. I looked, the toothless chains are only $15-$25 depending on size.

 

[jigs_n_fixtures]

Could you keep the stock clutch and sprocket, and convert the cutting head to chain sprocket? You could then fit a chain with the cutting teeth ground off, or perhaps just buy a toothless drive chain.

The Forest Service had some experimental units which were supposed to get you down to bare mineral soil, by flinging the covering organic soils all over the poor fool running it. They had a chain sprocket on the flinging head.

From one Pulley to another (last name is Pulley... ), anyway, looks like you could simply measure the OD of the Shaft, measure the ID of the pulley without the bearing. Find a needle bearing, press that into the pulley. If the pulley with the bearing in it has the same ID (excluding the bearing) you would have two or if it is indeed different that gives you more options for available sizes. There appear to be only three measurements that matter, OD, ID and length of the bearing.

Use a bearing press push in the new one. Looks like a fairly simple job to me, provided you have a press. If not put the pulley on two blocks and using a block of wood on the new bearing tap into place. Seat to about the same depth as the one pictured with the bearing in it.
