Thanks. I know nothing about these pumps, but pretty good at fixing things. Reckon mine needs a new repair kit. Took it apart yesterday, cleaned it, put back together, still no pressure. It's a yard sale pump, but engine is like new. I try to fix
.

NOTE! At 1:36 to 1:46 the have installed the seals backwards. Later they show the correct way to install them.

FYI the unloader uses 21mm wrench and the head bolts are 6mm Allen wrench.

found this in an on-line manual for this pump:Special Note: Use only AR64545 for the XJ/SJ/BK/RMW Series pumps only: Do NOT changeoil. Use oil only to add if low. This oil is a specially formulated synthetic with special additivesfor the demands of the XJ, SJ, BK and RMW pump series. No other oil is factoryapproved for these pumps, and could result in pump failure.

Got it.  "ND" is non-detergent.  This prevents foaming of the oil inside the case.

pump already comes with oil ready to install or need to add oil pump without dipstick ? i got a rmw 2.5g28

[ascaniboy]

Are the inlet and pressure valves the same part/valves?

[BiOsk]

What kind of oil goes into that pump. Many say ND w30. some say Synthetic Gear oil 75w90 and other say Marine gear oil w90. I bought usef pressure washer and I don't know how the last owner use it. I want to be sure that oil is clean and fresh to lube correctly and prevent overheating.

You didn't show how to repair the unloader valve. That would have been nice to see.

Seals @1:37 look like grooves up. Seals @2:24 are the other way around.

Art North thanks to share good videos about repair or replaced pressure pumps....

[Ramjet]

Is it possible to get just the manifold? It cracked and is leaking passed the unloaded. All the other parts are fine.

[metallitech]

There are two brass plugs visible. Is the smaller one a correct place to put a pressure gauge?

[kawmanrocks]

I have two or the RMW2.2G24 pumps. Neither pump functions. Are these pumps supposed to have flow from the garden hose through the pump head and out the high pressure outlet. Neither pump has flow either with or without the engine running. Thoughts?

[hamidashrafi]

I broke the seal, dumped the old oil, and refilled it with new oil. Now, I broke the pump, it is jittery and crappy. All check valves are damaged and need to be changed. What is the secret of not breaking the seal? Are they vacuum sealing it?

[lifeisgood]

Could’ve used the oil change procedure or level check

[netimages]

I emptied all the oil out and realized it does not take 30 weight oil. Then I finally was able to obtain service manual and it says that you’re only supposed to add oil but unfortunately I emptied all of the oil out. Now what should I do is there some kind of starter oil that needs to be added that I can get as well? Or is the pump going to burn out and become trash?

My AR SRMW2.2G26 pump requires a long M6 bolt to remove and replace the unloader valve seat (## THE VIDEO SAYS 5mm ##). My new unloader valve came with a M6 bolt. Unfortunately my pressure washer still shuts down when i release the spray wand handle. Looks like i wasted $28.

[macsawicki]

When you take the pump apart, what can be used to clean the existing parts? Does any of it require lube when reassembling?

Cómo puedo destapar la entrada de agua para este motor ??
