Tinkerdave
Reply: Ridged A/C

Tinkerdave

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.

WJA
Reply: Ridgid Portable Compressor

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.

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.

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

Question: Lower Piston Bearing

1092202

where is the bearing part number for the piston
WJA
Reply: Lower Piston Bearing

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,

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
Reply: Ridgid Compressor 45150a

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,

Question: Bearing On Motor

How do I replace the connecting rod bearing on the crankshaft without purchasing a new motor assembly?
WJA
Reply: Bearing On Motor

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
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.

I installed the rebuilding kit for this compressor a Ridgid (OF45150a) twinstack. Unfortunately the bearing I matched up from a bearing manufacture did not last, since then I was able to obtain the original bearing used by Ridgid for this compressor. The problem is the torque specs. I had for the connecting rod and head bolts were on my computer. My hard drive crashed without warning taking years of information with it.
If anyone can tell me the torque specs it would be greatly appreciated.

Question: Air Escapes Safety Valve

When the air pressure reaches 150psi the safety valve on my Rigid OF45150 opens and the compressor continues to run. Does the Safety Valve need replacing or the Pressure Switch or what exactly is my problem?
Rigid man
Reply: Air Escapes Safety Valve

Rigid man

Most likely it is your check valve. Pull it out and check for a broken "keeper" inside. They corrode and need replacing. (replace the whole valve). To get the small line off, push in on the brass ring(where the line goes in) while pulling out on the line. To reconnect to the new valve simply push line back in. It works the same as a "Sharke bite" for plumbing. If you are unsure, go to Home Depot and look in the plumbing dept and you will see how it works.(display) Good luck.

Hi Damian,

If the pump runs continuously but never builds over 25 lbs of pressure then you likely have a worn out piston and cylinder. The piston and cylinder are sold as a kit which is part #17968, available from http://ereplacementparts.com.

Good luck with your repair!

The bearing is a 6203, buy it at a bearing house as the manufacturer uses a cheap one, I would use a premium one
I changed my Rating to where I intended it to be originally.
After experiencing 'bearing failure' with my compressor and reading the multiple posts regarding 'bearing problems'; I've concluded that Ridgid 'dropped the ball' in not utilizing the best bearing available instead of the 'cheap O' they install in the compressor. Common sense tells me the bearings on the piston shaft are of the most used; endure the greatest amount of heat & pressure and are the most likely to fail is something is to fail. By my experience and the many posts regarding the failure of this bearing, I conclude that Ridgid skimped to save some money and subsequently lost this customer!
