Replace clutch assembly
Alan - June 13, 2016
👍 7 of 11 people found this instruction helpful
Tool Type
Chain Saw
Difficulty
Medium
Time
30-60 minutes
Tools Used
Socket set, Hammer and punch
Remove the outer housing. Remove the chain bar and chain. Remove excess dirt and foreign material. Removing the old clutch assembly is the most difficult part because the clutch assembly has to be struck with a hammer and punch to remove from threaded shaft. The thread is a left hand. Once removed, clean the area and replace the clutch assembly. Reassemble the chain bar and housing.

Difficulty
Easy
Time
30-60 minutes
Tools Used
Screwdriver, Wrench Set, home made tool to remove clutch
To replace Auto oiler you must remove the clutch and drum The chain sprocket showed ware so I replaced it also.To remove the clutch I made a clutch tool using a 2inch X3/4 inch 12 inches long piece of oak drilled 3. 1/4 holes matching the clutch installed drift pins in holes. to stop engine from turning over I inserted rope into the spark plug hole leaving rope hanging out so you can remove rope when job is complete the rope stops piston movement and allows you to turn clutch with out crank shaft movement. With clutch, drum and sprocket removed remove two screws from oiler and remove oil lines from ouler with out removing line from oil tank.Reverse order install new parts and the job is complete. They do make piston stop plug and a clutch tool you can order them through ereplacement parts when ordering your parts. Being a retired contractor with a full tool shop I Improvise when necessary. If you are a DIY guy buy the tools when placing your order and it will be an easy job.
