What oil to use in the power washer water pump

front seal, leaking oil means there is less oil in engine. continue and you will a new engine, have it repaired quickly.

you mean water in the pump oil ??? or engine oil ???



im suspecting pump oil... you didn\'t seal it properly or you have a crack somewhere in the main housing. rarely is it viable to repair these pumps... if you search a little you can find replacements pretty damn cheap !!!

You have to take off the pump head. Here is the link to the service for comet pumps.

There should be a little wondow on the side of the pump body to show you the oil level and a oil filler cap on the top of the pump body . There should also be a drain on the bottom of the water pump this is not the engine its the water pump . It will take 10 -30 or 30 wieght oil check your manual or local dealer for your specific pump oil requirements . But if you use it often change it don't add and do the engine oil tothis is the biggest killer of pumps and engines and pumps nelgeliting oil changes also eighter drain all water from the pump or winterize in freezeing temputers

If the oil plug bolt is leaking you need a new aluminum sealing washer. There are no oil weep holes in the front of the motor. Is it the weep hole under the water pump? You probably have a bad water pump seal or a bad oil seal on the water pump shaft. Buy a new water pump and the K&L water pump gasket kit. The K&L gasket kit comes with all the gaskets, seals, and washers necessary to do the water pump replacement for a fraction of the cost of the OEM Honda individual gaskets, seals, and washers.

You have a seal on the pump between the pump and the water pump thats leaking you have oil and water mixing . I owen three mechines and i don't understand what you mean when you say the oil filler stem. I also rebuild power washers and pumps. If you can clarify where the water and oil mixture is comeing out then i can tell you excatly what the leak is thanks

Hydraulic oil?
Is this a pressure washer?
Pump should be half full of SAE20 or SAE30 non-detergent motor oil.
Engine should have 10W30 motor oil.

If you have a pressure washer ... and not water is coming out end of gun:
Take all hoses off machine.
Look at incoming water hose connection.
The should be a filter washer.
Clean or replace filter washer.
Hook up water and turn on water.
Water should come out other side of pump.
Turn on power washer and see if water coming out of pump is pressurized.
Now hook up pressure hose without gun.
Turn on pressure washer and see if water comes out of hose and is pressurized.
Finally, the gun may be bad.
We used to replace guns when they went bad.

Good news, your engine runs
But your pump may be bad

Here's how to test your pump
Check oil as outlined lower down
Disconnect the washer hose and gun
Connect water hose and turn on water and water should pass straight through the pump
Look for clogs in the hose-end where water hose connects to machine

Turn on machine and see if water shoots out pump
If water shoots out of pump, but no water shoots out of gun, then you may have a 'mud-dobber' wasp clog in your washer line or gun

Look for clogs in the end of each water connection.
Now connect washer hose without the gun, tun on the machine, and see if water shoots out of washer hose
Finally, the gun trigger mechanism may be bad
I don't know which gun you have ... but we replaced guns on our machine now-and-then ... google-search power washer guns for a replacement

Check your pump oil
Pump oil is SAE20 or SAE30 non-detergent motor oil
Pump should be no more than 1/2 full of oil
Use plastic hose to drain pump oil
Do not turn machine on its side or turn machine over or engine oil will run into carburetor

More than likely you have water leaking into your oil, making the oil float on the top and out of the vent. Eventually you'll only have water, and no oil. Drain oil and replace. You will probably have to replace the seals between pump and crankcase. Only remove front of pump,(brass part) if you catch it in time the bearings in the rear portion won't go out. Do it now before the water wears the pump out. You can get parts for most pumps at www.pressure-washer-parts.com. Or go to www.cometpumps.com Hope this helps.

This sounds like a heat transfer problem

You should check that the oil reservoir for the pump has oil in it. It sounds like it may be low. Also, if it is a gas model, the engine oil may be low.

Remember the pump oil reservoir should be only 1/3 to 1/2 full of non-detergent oil.
