Husq. 136 sprocket worn

[Ozarker]

I have a husq. 136 that I messed up. I was cutting and I guess I got the bar pinched in a tree, which bent part of the rails in on the bar. Which caused the chain to not move freely, but I didn't know it so I kept running the saw. After a while it wore a deep groove into the sprocket that drives the chain. Now the chain gets hungup in the worn groove and won't keep a constant tension or jams up. How do you get the sprocket out, and can a newbie do it without any special tools? I see the bolt on the opposite side....

Also somebody is giving me a husky model 36 with a shot motor, is that part interchangeable with the newer model?

Thanks

you need a piston stop (rope will work) to open the nut on clutch side and after thats opened you can remove the clutch and change rim (or clutch if its spur type), and i also suggest that you get a new bar asap before getting back to cutting (after fixing sprocket)...

Thanks, I already got a new bar for it. The piston stop using a rope method, do you just wrap a small rope around the sprocket thing and tie the other end to something so it won't turn? Just guessing.

You pop off the top cover, pull the spark plug, bring the piston to just below TDC, and stuff the rope into the cylinder through the plug hole. This will jam it up to remove the clutch, without harming the engine.

Thanks for the tips, this will hopefully let me get her back and running. Still got lots to cut after that big ice storm a couple weeks ago

You can also use an impact gun in lieu of a piston stop. I know it works on the bigger saws, but presumably yours has enough compression (and a strong enough crank) to use that technique.

I have a 136, the clutch will be LEFT hand thread, the clutch will turn clockwise to be removed. there will be a washer under the clutch, be sure to re intall it. this is also a good time to grease the bearing. There is a special tool to remove the clutch, but once you get the crank held with a piston stop or rope you'll figure an easy way to knock that clutch loose.
