Trying to remove the fan on model 919.166442

Trying to remove the fan to clean the brushes and change the capacitor. 919.166442 ,1.5 hp, 15 gal.


Afraid of boogering up the fan trying to remove it.

I believe the start capacitor is failing, because there was a burning smell and the compressor won't start without a nudge.

fixed...?

Well, after figuring that my compressor was kaput, I decided I had nothing to lose by tearing into it. I locked the fan in place and took out the vice grips to get the retaining sprocket off the fan. (DON'T DO THIS!) they obviously put grooves around it to make you THINK it twists off. The fan pulls off. I used a tool that came with my buffer, a metal fork, to lift the fan off.

I airbrush so the motor was totally covered in over spray. I cleaned the entire thing with acetone since I know that will remove the types of paint I spray.

I cleaned everything. Head, piston, copper wires, and the center, what is it?, magneto? And on the end of it is a plastic piece that has two spring loaded metal blocks. (Be careful not to stretch the springs too much). I cleaned inside those channels so they moved easily.

I bought some gasket material and made new head gaskets.

And it works! No more excessive sparking. Now more nudging to help it start. I do have to buy a new little fan because I ruined the grooves on the plastic fan trying to twist of off. (DON'T DO THAT!)

I want to change from the yellow coiled hose that cam with this model, Craftsman 921.153101. What size black rubber hose can I use?

Jerry, fill your boots! Use any size hose that you want and that you can get the fittings for.

A bigger hose takes longer to fill from the tank, yet it also means that you have more air to use right at the tool.

I have a small DIY air compressor at home too, and it originally came with a 1/4" vinyl hose. Not only was the vinyl a pain when it got cool (wouldn't bend, wouldn't lay flat etc.), it didn't transmit enough air for my liking. So, I have a 1/2" I.D. (hose is measured on the I.D.) rubber hose. It's easily handled even when cold and flows a lot more compressed air.

Cheers,

Bill
