Noisey bearings, damaged cord
Richard - June 28, 2017
Tool Type
Circular Saw
Difficulty
Easy
Time
More than 2 hours
Tools Used
Screwdriver, Pliers, Socket set, Wrench Set, Nutdriver, Torq drivers, T-20, T-25
Completely disassembled saw, cleaned all of the parts with mineral spirits and some degreaser soap and water. Bearing removal was the most time consuming, but having a couple of years working in a electric motor repair shop helped ease the job. I'm retired and every day is Saturday, and you do what ever you want on Saturday, working on the project whenever ya wanna. This job was for a friend who makes his living remodeling old houses. The on line parts list and schemes are also a benefit. The saw was a Milwaukee and the model was one of the better quality ones which does help make it easier. These are fun jobs I enjoy doing, working with my hands. Will be 79 on September 11. Helped family marry off oldest grandson June 17 in East Jordan, MI and will be in Bozeman MT over Labor day week end to marry off youngest grandson. So repairing tools comes in between. Do appreciate good service from ereplacementparts.
