Stihl 029 clutch replacement

[mike0000]

Looking for some direction, I need to replace the clutch (under drive sprocket) on my old 029, it’s close to thirty years old. My attempts to break it free have not worked so far, it is really stuck. Is it a bad idea to remove the spark plug and insert some rope to lock the crankshaft in place? I’m concerned I could damage the rod or piston trying this. It’s currently soaking w/ acetone/transmission fluid. Thanks for any recommendations.

Scratch that, I just hit it with the impact driver after the acetone transmission fluid soak and it broke free!

Our local Rural King has a full time Stihl rep there in the Saw section. He can get parts.

The impact method has been known to shear the key for the flywheel on the other end. Stihl makes a simple tool that acts as a piston stop.

Good to know, hopefully that didn’t happen.

Thanks, I’m headed to our RK in the morning in search of parts, hopefully they can help me out.

I use the rope method most of the time. The stops can get broken off inside the cylinder if they don't fit right. I compress the piston against the rope or stop and loosen the clutch with an air impact set on low. Works fine.

I've used a rope as a piston stop on an 029 (and many others) many times. Then I bought the plastic piston stop and have yet to use it in the 10+ years.

Depends on your RK for parts. One north of me sells stihl and one south of me husqvarna.

I ended up stopping by a local store (PC Lumber) they sell and service Stihl saws. They had the parts I needed.
I borrowed my brothers new Stihl MS 261C while my 029 was down. I was amazed at the difference in power, I decided to pick one up for myself. I went with the same bar length so chains will work for both saws.
