Drive pulley had broken loose

1-2 hours
Tools Used
Screwdriver, Pliers
Disassemble sander to remove broken drive pulley. Replace with new. Be sure to have extra lithium grease to replace what is lost in disassembly.
Note the order of the pulley, washer, key, gear, etc. as you remove the fmdrive pulley to reassemble with new parts. It will take longer to dis- and reassemble the unit than you'll spend in replacing the drive pulley.

Watched U tube videos. Guy in Europe repairs tools and makes great videos. Got parts breakdown drawing from Mfr website. Broke down tools, found broke parts, ordered all needed from eReplacementParts and put tools back together according to video. Tools broke due to user not following recommended maintenance of grease every 6-months.
Note: lock ring pliers are not the same as snap ring, and really help with this tool.
