  • ridgid air compressor help

    i have a ridgid gp90135 wheelbarrow gas compressor. when i start it up it builds air pressure in the tanks. pressure set 100psi. when pressure get to the max instead of switching the throttle underloader off so no more air goes to tanks the motor shuts down. i would let the pressure out start again and the same thing happens. tried many times will always the same result. whats wrong with my compresser? im building a room and need it now. its 2 years old with not much use. i dont want to send out. i can fix myself. just need to know the problim and have the part asap.

    Possibly a defective unloader valve.

    See Page 16 for trouble shooting, and the parts list at the end:
    Manual

    Hope that helps,
    Ern

      there is a adjustment but not much out there on how to do it. very simple to take apart and put together. just can figure how to adjust. they should sell rebuild kits and how to. unit looks very eady to rebuild. why buy the whole unit if there is one defective part or o ring inside. the cost of a o ring or any other small parts inside should not cost alot to get. buying the whole thing is $70.00 plus shipping

        is the unloader unloading the air pressure or the pump? or is it stalling the motor from over load, if it is stalling then the unloader is most likely dirty or faulty, (most of the time if the unloader is faulty it will keep building pressure until the safety valve blows),

        if it is unloading and then dieing then (and the manual gives some indication it is a idle down unit at least there is some throttle control in the parts list off the unloader),

        but is

        or will the motor idle, is the carburetor idle jet clean? is the fuel good, in other words is it good enough fuel to allow the compressor enough power to idle?

        If it is dieing on the idle down (disconnect that from the motor) if it is a have to use situation, and use it and figure it out later), the wear will be a little greater and the fuel usage greater but it should not hurt any thing if the motor runs steady,

        (I have dealt with some gas power air compressors but none had the idle down feature, only an unloader that dumped the air or shut down the cylinders from pumping)

        these were two thoughts I had when I first read the post.

        first you need to figure out is the problem in the unloader or the motor

          i did find a step buy step on how to adjust low psi and hi psi. i had it running great turn on and off when it was supose to . then just before dark i i started to see if was still fine. it started fine and as i build pressure to the high psi the engine stalled. so in gona start from scratch and reset step by step. what other things can cause the engine to stall at max psi

              Ok, I'll give it a try...

              First thing we need to know is if the unloader is working. Watch the throttle on the engine. Does the throttle close when the set PSI is reached, just before the engine dies? Do you hear a little "poosh" of air just before the engine dies? That's where we need to start - try to determine if it's an unloader issue or a carburetor issue. Both issues are fairly common.

                  She's doing far better than she would be expected to at this point. There's no substitute for researching surgeons and choosing the one at the top of the field.

                  You? Learn from me?
                  I'm honored. Thanks. My hat no longer fits.

                      i figured it out. it took me 3 days but i learned alot about the compressure. it was the gas cap. vent must be bad. when it ran it wwould for a while then stall after it sat i would start right up. 2 days ago i checked the bowl for dirt ant the float. bowl was full. so thats how i got throne off. i got real lucky after ajusting the unloader many times and trying different settings it would start then stall. i thought to myself its acting like its getting no gas but the tank was full. i took a bowl screw off and no gas coming out. took cap off and gas came out. so i adjusted my loader to were i wanted them with cap off. now every thing works like it should. just wanted to share watch out for the gas cap on these. thank for the help Bill
