by Loren
(Dickens, Iowa)

Hello,

I have a just bought a smith 100D 100 cfm 125psi 302 ford, tow behind compressor .
As soon as it starts it runs wide open and when I close the main air valve that goes to the hose the motor dies . Does it ever go to IDLE ? Is this normal ??

after cooler
by: Loren

I found a leak in the after cooler will this cause the unit not to idle down? And if so is it a big job to fix it? Thank You, Loren

Not normal. Could be pressure sensor or engine control stuck/jammed.

Compressor wont build psi past 40? - FORD SMITH compressor V8 engine

by james
(bergen new jersey)

I have a tag along FORD SMITH compressor V8 engine.

four cylinders work the gas side and four for the air.

I have replaced the pilot valve and cleaned all the 1/4" copper tubing that regulates the flow.

I have checked and found no leaks.

From the research I have done, I am lead to believe that it may be the intake valves (4) of them or the reed valve.

Will the reed valve be off to the side of the valves outside the block?

If it's not the reed valve and I have to check the intake on the valves how is this done??

James, your post is live.

Grom what you have written, I would, too, look to the intake or pressure valves as the probable cause of the compressor symptoms you note.

I hope someone that has some experience in working on FORD SMITH air compressors can post some mechanical help for you.

Cheers,

Bill

Starter
by: Al

Dont know if this has been resolved. I learned that the auto parts starters do not last. Went through 2 of them within a week.

I went to starter overhaul and repair business that has been around since the 40'start in corpus christi tx. In fact they had a manual for starters for these types. The Name is cc battery.

Excellent knowledge and in fact asked for detail information about the starter and compressor.

What was most important was the distance between the pop out gear and the fly wheel. Haven't had a problem since. if you have a place like this in your area I'm sure they will get you what you need.

Is there anything in particular you need?

The motor/compressor parts are pretty much from the mfr of the engine.

smith not starting
by: Anonymous

Make sure you have dedicated current to the on side of the switch when the switch is on . Not in the start position

Can you tell if it's actually firing, or just turning?

Fuel present?
check fuel and air filters.
Maybe battery is weak? Loose connections?

There is a link to a manual at "today's tractors"
under title "Smith 100 Portable Air Compressor"
