Due to new switch having the connection screws in a different location, I had too extend one of the wires. Other than that everything went pretty smooth.

Tools Used
, Bearing press
Replacing the switch and handle was easy. Replacing the cog and the bearings can only be done with a bearing press. Tried a pulley puller and heat, no way. Fortunately my brother works at a garage and used an industrial bearing press. It's the only way, don't break the gear it is no longer available.

Professional tool repair shop couldn't provide replacement switch- your employee made an extreme effort and discovered the switch is available when purchased as part of the handle replacement kit. Her efforts and professionalism saved me from buying another $250.00 grinder. I'd buy her lunch for that! She did a really great job, and I took her work to the professional tool repair shop to show them how to get it done with your company's parts supply!!! The repair of the tool was super-easy, just followed instructions provided, and my big grinder works great.

The switch kit includes installation instructions and a wiring diagram. Made it easy. Then I just removed the brush caps, and removed the old brushes and installed the new ones, then screwed the brush caps back on.
