Question: Clutch Assembly

orca

How I remove the clutch assembly ? Thank You.
WJA
Hello orca,

We have an article and video on the proper way to remove a clutch assembly. Your clutch is a little different from the one shown in the video. To remove yours get a screw driver and hammer and sharply hit the clutch and it will thread off. Here is the link to the article.

How to Remove a Trimmer Clutch
