Question: Alternatives?

tkgguy

This hose is back ordered here, and on link removed they say it is not available online. Is this something I could procure locally at say an automotive shop and fix myself, or is this a way to get people to bring their compressors in for service?
WJA
Hello tkgguy,

I would think you would be able to get this hose at a local compressor service center in your area.

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: Pressure Switch Part

railkid

Where can you get a replacement part?
WJA
Hello 1214594,

You should be able to substitute the Ridgid 17908 Pressure Switch, with the Campbell Hausfeld CW214300AV Pressure Switch.

Question: Ridged A/C

1183322

I have a Q? I just replaced the piston and rings on my 45140 ridged air compressor and now I cant get it to pump up with air ! can you please help me out ?
Hi,
Well most of the time replacing the piston and ring is straight forward.Did you have the head assembly apart and if you did ,was it reassembled correctly.Remove your air filter and out put line and make sure your get vacuum from the intake and pressure from the out put.If not or its low check your head gaskets and reed valves.You should have also replaced the cylinder with the piston and ring.Lets us know what you find.Good luck.

Question: Part Number ?

mikewells8221

is the manifold part number 35023 the same as 17793 without gauges and check valve or are they compatable
WJA
Hello mikewells8221,

I couldn't find a part number 35023 on our site. So I don,t have it to compare with the 17793 regulator/manifold.

Question: Ridgid Portable Compressor

jrioux

I have a ridgid portable electric twin tank compressor that pressurizes to 135 and shuts off but escapes from the little hole on the pressure switch above the the tank pressure line. I have already replaced the pressure switch and the relief valve. What do you think the problem is?
rigid of45150 :runs to 75 lbs. and get no higher but continues to run,air appears to be leaking from regulator valve ,opened pitcock with much rust coming out,pleez help
WJA
Hello mikewells8221,

If your regulator is leaking air, you'll probably need to replace the complete 17793 regulator assembly, since they don't supply a regulator repair kit. As for the rusty water coming out of the petcock valve. It is a good idea to drain your tank every time you use it. Condensation builds up in the tank and that's where the rust is coming from.

-WJA

I have already replaced the pressure switch and the relief valve. What do you think the problem is?"

If the compressor leaks out air after the compressor stops try this. Down on the 17728 Check Valve some of the check valves have a cap that can be removed.(make sure your tank is drained before removing the valve cap)Under this cap ia a spring and small rubber disc.This is your check valve.If this does not seal correctly high pressure air will bleed out and exhaust itself through the pressure and/or head assembly.Look at the valve to make sure rust and scale is not on the seat preventing the valve from closing all the way.Clean it good and try it again to see if your getting a good seal.If it continues to leak replace the check valve.Hope that helps.Good luck.
Tinker
hi thanks for info,i had just purchased this compressor(of45150a)@pawn shop for $40 bucks,i knew it had issues but i couldnt pass up the deal,upon further investigation i realized the fan shroud was missing,and the regulator is only leaking a little while it is turned down low,ive read a few other replies and quotes and was thinking that maybe the pump or compressor motor rings might be worn hence it wont produce more than 75 lbs.,does this sound right,and is there a rebuild kit available that wont cost so much that it wont be worth it financially,is rebuilding able to be done without special tools and knowlegde only know by rigid certified techs please help
how do you check compression on compressor motor(pump)?
Hi mikewells8221,
You will need to disassemble the pump and visually inspect it.This is the only right way to see what the trouble is.
Tinker
thanks for all the help i put a piston assembly on my rigid of45150 after visually inspecting it,now it will run to about 135lbs and blow the check valve please help,thanks
Question: Lower Piston Bearing

1092202

where is the bearing part number for the piston
WJA
Hello 1092202,

The bearing for the lower piston is on the electric motor. If you look at page B of the parts diagram. You will see it right in the center of the motor on the end. Your best bet to have it replace is to take it to a qualified electric motor service center. They have the special tools and equipment to replace this bearing for you. Unless you have some experience in this field and you feel as if you could do it your self.

Hope this helps,
-WJA
Question: Ridgid 0F45150A Oiless Air Comp

1091355

keeps running. is it the pressure switch???
please help
WJA
Hello 1091355,

I would first think that it is a worn 17968 piston/cylinder assembly. Worn rings allowing air to blow by. Or it could be the 17983 valve plate kit.

Hope this helps,
-WJA
Question: Ridgid Compressor 45150a

budcecil

The compresser will usually cycle 2 times and then quit. It smells like something is burning and if you let it cool it will pump up again. Pressure is good and I have it plugged in to a 20 amp circuit with no extension cord. Does anyone have any ideas what is wrong?
WJA
Hello budcecil,

Check the windings in the motor, it sounds like the insulation is starting to breakdown and after a while it will get hot enough to set off the internal overload. If the windings are dark in color and smell like burnt insulation. I would think it is time for a new compressor.

Hope this helps,
-WJA
Question: Bearing On Motor

bqbuild

How do I replace the connecting rod bearing on the crankshaft without purchasing a new motor assembly?
WJA
Hello bqbuild,

You can identify the bearing by looking on the rubber or metal shield in between the inner race and outer race of the bearing. A local bearing supplier should have one in stock. You will need a bearing puller to remove the old bearing and preferably a press to install the new one on the shaft. Or you can take your motor to a local electric motor service center and have them do it for you.

Hope this helps,
-WJA
Question: RIDGID OF45150A Compressor Probl...

hunter5

I have a RIDGID dual tank compressor model OF45150A that I recently replaced the piston and cylinder assembly on because it would not build pressure. After replacing these parts the compressor takes 20 minutes to build pressure to the point where it will automatically shut off. That is the first problem. The second problem is that after I start using the compressor it will not maintain pressure. I have to keep stoping what I am doing and give it time to build pressure again. Could there be another issue that I need to look at and if so where should I begin? The regulator does leak a little but it has always done that so I do not think that the regulator is the issue.
Hi Hunter5,
Any time you replace the cylinder and piston/rod in a oil less compressor you need to replace the reed valves.That is from the top of the cylinder to the bottom of the cylinder head. It sounds like you have a worn reed valves.Also check the check valve out of the tank.Hope that helps.Good luck.

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.

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,
