Question: Automatic Power

dominguezerik

Why won't it shut off by itself ? How can you fix that ?
WJA
Hello dominguezerik,

One common reason these types of compressor will not shut off is because of blow by. This is when the piston and the cylinder are worn to the point to where the air that is supposed to be being compressed, is leaking past the piston and the cylinder. You would have to inspect them both to see if there is any wear. If there is you would need the 17968 Piston /Cylinder Assembly (Main Bearing Not Included. Use a 6203.. It also wouldn't hurt to install the 17983 Valve Plate Kit.

Question: Ridged Fan Kit Removal

1223737

which way do you remove the fan screw? clock or counter clockwise?
WJA
Hello 1223737,

The screw on the 17988 Fan Kit, is a left hand screw, so to remove it turn it clockwise.

Question: Ridgid Air Compressor

1183819

Ridgid air compressor, the small 2.5 gal model - motor runs but not pump. Suggestions?
Hi,
Well most likely the teflon piston ring has broken.Remove the cylinder head and look at the piston and cylinder.If they look good I'd look at the reed valve assembly.Hope that helps.Good luck.

Hope this helps,

Question: Compressor Can't Reach 100psi

1055134



My compressor can't hit 100psi anymore.
It seems to slowly be getting worse.
There are no leaks, and most of the guages are bypassed including the output regulator.

Any ideas on what it could be?
Hi Markavelli,You will need to replace Piston /Cylinder Assembly Part Number: 17968.If you take the pump apart you'll see that the piston fits loose in the cylinder and/or the piston ring has peeled away fron the piston.This is what causes about 95% of the problems.Hope that helps.good luck.

Question: Connecting Rod Bearing

Leester

my connecting rod bearing failed. where can i find a replacement. #OF45175
WJA
Hello Leester,

If you take the motor to an electric motor repair shop. They should be able to pull the bearing from the shaft and replace it with a new one. The manufacture does not supply this bearing.

-WJA
Question: Fan Kit

smail88

If they do not sell the fan kit anymore what do you use as a replacement? My fan is shot and I need to replace it?
WJA
Hello smail88,

I checked with the manufacture and the fan kit, part number 17988 is available and in stock the factory. Thank you for bringing that to our attention.

-WJA
Question: Rigid Model OF45150A

cxcook

Does the Piston & Cylinder Kit come with gaskets?
WJA
Hello cxcook,

The Piston/Cylinder Assembly part number 17968 does not come with the gaskets when you order this item. They would have to ordered separately. The part numbers for the gaskets are, 17958 Cylinder Gasket, 17973 Head Gasket, and 17978 Discharge Gasket.

Hope this helps,
