Craftsman String Trimmer

Posted by kenmist8193 7 (My Page) on

My gas trimmer Model 358.795521 has stopped "trimming". The trimmer head doesn't rotate when motor is running and trigger is activated. The trimmer head can be spun by hand which probably means it is not in contact with the trimmer shaft. I have removed the trimmer shaft from the motor and pulled the shaft from the housing. It is not broken and appears to be undamaged. Both ends look good, no indication of either being stripped or rounded. When trying to insert the shaft back into the housing at the trimmer head or bottom, it doesn't insert all the way. That leaves about one inch extended at the top of the shaft which I think should be flush with the top of the housing. Since the housing is recessed into the motor which would still allow the shaft to contact the upper joint to connect properly. I'm not sure if the problem isn't the gear box itself? Any suggestions?

RE: Craftsman String Trimmer

Can you post some pictures or take closer looks first. I question a piece of shaft being broken clean that is not noticeable.

1. Is it a flexible cable type shaft with square ends or solid with splines?? Either way look for a clean break.
2. Look in the motor’s clutch hub and the string’s head close for a piece of shaft.
3. Start the engine and see if it is powering the clutch shaft that the shaft fits into.
4. I feel it is the light flex cable shaft, fold it and wire the ends side-by-side and take a Pic and post it.
5. Send clear close-ups Pics where the shaft fits in the clutch and spool.
