This is the only sight I thought I might get help on. I have a power washer that does not (now days) put out high pressure. It used to but not today. Is there any WWW I can get info. from that might help me or can someone here help? I really need it. The PW has not been used but about 6 times since I had itfor 5 years.

Thanks
Don

 

Az:

You will need to give us some info. on the power washer.
What is the model name and number?
Is it gas or electric?

 

Here is some info. that should help (I hope)
The name of the PW is Generac
The Model number is 01292-2
Type 6670CP

It is supposed to produce 2300psi
It is gas driven.

Thanks
Don

 

Hello Don!

Check to be sure there is not any debris clogging the screen where the water hose connects. If not, you'll probably have to remove the valve body from the pump and disassemble it and clean it and the valves up. There is likely water deposits in there and possibly some debris stuck in the valves. There are lots of pieces, o-rings, springs, etc... and if you aren't careful, you'll forget how it all went together. You might want to get an exploded view of the pump first to help you get it all together right.

Once inside, you'll probably find the problem, like a blown "o"-ring, rusted through spring, stuck valve, etc...

 

Don:

it sounds like you don't have a manual for this PW. If you do have a manual there is a lot of good info. in there on maintenance and a trouble shooting guide. If you don't have a manual you can download one from: http://www.pressureparts.com/partsinfo/
I wouldn't get in to that pressure pumper until everthing else has failed.

LOL

 

Hi again guys
I got a manual on the PW, so as to be able to do what Cheese suggested. Here is the problum. The parts breakdown shows the parts but it does not tell what has to be taken off first to get to the valves. I thought I had a plan. I removed the four bolts that holds the pump on. The pump did not want to come off very easy; so I banged on it. Still no affect. I then put it back togeather. Started up the pump and it leaked where the pump was attached to the piston guide. I tightened the bolts as tight as I could trying not to strip them.
I will hate to have to take it to be repaired, bacause the only income I have is SS.

Thanks again,
Don

 

Did you try the site that rogerh reccomended? It has an exploded view of your unit. Good site!

I probably jumped the gun a bit by sending you to the valve body/manifold, but that is where I almost always find the problem with these things. You want to make sure your hose is not restricted, inline screen is not clogged, nozzle is clean and properly adjusted, etc...

The pump is probably stuck to the crankshaft. It happens a lot on pressure washers with all the water...the shaft rusts. You may not be able to remove it without ruining the pump. The valve body is on the end of the pump, probably brass, and has 3 threaded plugs in it. You remove these plugs to pull the valves out. There are more valves in where the body bolts to the pump.

I'm not sure what you are referring to as the piston guide.
