Intermediate DIY

Not a walk in park. Bell housing and augers need to be removed. Mine is an older unit. Needed Steel wool, proper grease and a few hours to do the job right. PS pay attention to auger, I had to do job twice because I put augers on backwards.

Worth the time to fix.

Fix it or throw away? I chose ro fix it. Took me over 3 hours to break down and remove the damaged worm gear. Things went faster putting it back together.

Gear box brass gear, seals, and gasket

Received parts for my old snowblower quickly and accurately. Can’t believe they actually still had them!

Fairly difficult installation

First take apart the blades and shaft, then use hammer and punch to remove the auger gear. Sanding to remove debris from the shaft will help to remove the gear.
