Troy-Built 2-Cycle Trimmer

The pull cord recently frayed and broke off near the attachment on the pulley/starter inside the engine housing. I am trying to disassemble the trimmer to get to that part to replace the cord, but can not figure out how to remove the 'clutch rotor assembly' (as called out in the parts breakdown from MTD).

Does anyone have any knowledge of how to remove this part to release the engine housing or can point me in the right direction?

You didn't tell us what model teimmer u have.But most string trimmers these days has a small screw inside the clutch drum where the drive cable goes that has to come off first.

Without using special tools, you can push some pull rope down in the spark plug hole to stop the engine from turning, and use a brass punch to knock the clutch in the direction required for removal.
