Champion compressor auto-drain repair

[tq60]

10 year old compressor started to have intermittent drain down of air.

Most of the time it holds air for weeks but sometimes empty next day.

Checked the auto drain and there was air coming out of the drain.

Pulled it off and apart, simple device, but the valve seat was pitted and the rubber washer shaped object also messed up.

Found rebuild kit online for 40 or so bucks but no seat.

So we made a lap to dress it.

Could not find the grinding compound I know I have several of...did find some air brush erasing compound, mixed with oil and made some.

Lapped the seat while the lap was still in the lathe, when done we cut it off and made it for a hand drill.

Upon examinining the valve it looked a lot like a fawcet washer, in the b.s. of washers we found one close, drilled out the center and good to go.

Works like a champ!

Simple hand valves existed a long time before automatic valves and worked just fine, you just had to remember to drain the tank occasionally.

We got a response from local dealer with 30 dollar cost for The rebuild kit.

Online was 38 and up plus shipping.

The diaphragm on ours looked like it had some blisters so for 33 out the door we got one as a spare, it goes inside the mag starter and outside marked as such.

This way we are ready to go as parts may be harder to find later.

The washer we used is tapered similar to the one in the photo.

Washer it kit is flat, reformed in use maybe.

May visit a local well stocked plumbing supply and get closer fit spares.
