Brian, will this type unloader work with a cat pump 66dx40. It appears to have the same bolt pattern. Thanks for another informative video.

[@Brian_the_repair_guy]

If you have an unloader that is bolt on, you can convert it to the external style

[@twb605]

Hello Brian. Enjoy the way you share your experience and knowledge. I have an old Farm Hand Pressure Washer that uses a Giant GX2525 pump. It stopped working so I ordered a rebuild kit. The old problem is solved, but this Giant pump has a built in unloader and I must have something wrong with my assembly of new parts. To start the engine I have to squeeze the wand trigger and if I release the trigger the engine stalls from the pressure. I have a series of pictures I would like to share, but don't know how to send these without an email address and you might not want to share that. Any other way? Thanks

[@Brian_the_repair_guy]

Your pressure is most likely set too high for the engine. Give it about 3 turns counter clockwise wise and try again

[@D-boi93]

Quick question, mine came already setup remotely how you did in this video. But I’m going to add a buffer tank. So I’m going to run the bypass to a tank, do I need to run a line back to the lower barb? Or can I just run my garden hose back to the inlet to the pump. If that makes any sense. I was thinking of making a video of the process I’m going thru from my first pressure washer to the whole setup and so on as I upgrade equipment. If I get likes in this comment I just might… lol

[@benjaminbutler3487]

would the external work if you just bolted the external to the bolt on and set the bolt on to max and set the external to say 200 psi less than the bolt on?

[@Brian_the_repair_guy]

Yes is the short answer. The only way to attach both, would be inline. There would be zero purpose in doing this. This infact opens the door to more possibilities of failure.

I have a water blaster and it has a bolt on banjo style unloader. The unloader has its own brass style short bypass system. I noticed a small Allen head plug at the back of that bypass tube. Im assuming if I pull that plug I can bypass straight to my tank. Bypassing the original brass tubing down and back to the inlet. Or should I just replace the entire unloader with and external? It’s a aaa belt driven pump

[@Brian_the_repair_guy]

To determine if you can use it for a tank, pull the Allen screw out. Once it is out, run the machine. It should run water with the trigger NOT pulled. Whwn you pull the trigger the water coming out should stop. If it does not, turn it off. If it does stop with the trigger pulled you can run it the tank. Now, if you are not pulling FROM the tank, the tank will just fill.

[@chrisrotan7280]

Can you put a link to where to buy the external unloader you are using here?

[@OdinsCloud]

I have a Honda powered, belt driven CAT pump with an external unloader. A few times the I had noticed that the unit did not make pressure. The machine has VERY low hours, is very well maintained too. I have determined that the culprit is the unloader an d sometimes gets stuck. I was thinking of replacing the unloader or should I open it up and reseat everything?? This happened only once this year and turning the adjustment handle remedied the situation. I used Stabil "Pump Saver" over winter last winter as opposed to normal RV anti-freeze the previous. Perhaps greater lubrication of the Stabil (plus it foams) helped loosen up the unloader.?? If you have any thoughts of experience I would appreciate it..

[@Brian_the_repair_guy]

It is not uncommon for an unloader to get stuck. It sounds like this is very infrequent. Lack of use can be a culprit. I wouldn't be too concerned based on what you have explained. Not sure I would go the expense of replacing.

[@OdinsCloud]

@@Brian_the_repair_guy Thanks Brian.. I think it is definitely lack of use. I use it to softwash two homes. With X-jet or down stream. It's a small commercial unit but used residentially. I plan on using it for a boat in the future and picked this because it can run off a tank. It's 4gpm as presently setup but changing sprockets I could get 4.5 or 5gpm states CAT. Would drop pressure from 4000 to 3500. i don't think it would save me much time because i do not do this for a living. in fact the extra pressure might help me for barnacle removal..?

[@kashi2843]

Brian great video, I had a question - would it not be better to prime the 16mm rubber hose with water before fixing at unloader side. my worry is about the air pocket in the hose, so when the internal water pressure matches the selected unloader pressure the bypass will activate and then the air pocket will enter into the pump will this not cause damage? are there any best practice advice to prime this type of triplex plunger pump with external unloader before use 1st time?

[@Brian_the_repair_guy]

To prime the pump, attach your water source at connection. Turn water on and allow to flow freely for 5 seconds. This is more than enough to ready the pump prior to starting engine. Do this each time the machine is going ro be used prior to initial start

[@kashi2843]

what about the unloader valve air in rubber hose pipe@@Brian_the_repair_guy

[@Brian_the_repair_guy]

@@kashi2843 if you utilize the steps above, then the system is primed completely

[@tomwebb986]

Does this setup stop the pump from overheating? Usually I have seen the bypass water getting dumped on the ground or back to a buffer tank so it's always fresh water going through the pump...

[@Brian_the_repair_guy]

The external or remote style unloader does help reduce heating. If it is dumped on the ground or in a buffer tank, it is greatly reduced. Recycling the water in a short hose does reduce heat, but not as well as the other two options with this style unloader

Hi Brian, Thanks for this great video! I have a question: Could I replace the factory unloader on a 4400 PSI 4.0 GPM Dewalt Pressure Washer with a remote unloader like the one you show so I can have the water cycled to a buffer tank? The one it comes with is has a Thermal Release Valve that opens up to release a gush of water in an effort to lower the temperature inside the pump; I wanted to remove it and connect a hose to that fitting and run it to a buffer tank but I was told by Dewalt not to remove it because it could cause damage to the pump. I wanted to see if you had dealt with this type of scenario before and if you knew of an unloader I could buy to replace the one it came with and be able to use a buffer tank with it. Much appreciated.

[@nhpowerwashinglawncare922]

Can you put qc fittings between machine and unloader

[@Brian_the_repair_guy]

With a bolt on unloader, the answer is no. The external unloader can, but the fittings could possibly reduce the flow rate. The interior diameter can not be smaller than the original fittings.

[@stevem1081]

The only small inconvenience I noticed, when you screwed the hose onto the unloader, the screw on the hose clamp ended up facing backwards to where you couldn't get to it later.

[@stevem1081]

@@Brian_the_repair_guy true, and I always pick the correct/better way.

[@Brian_the_repair_guy]

@@stevem1081 I will explain why I do it this way. After a few uses, that hose will not come off that barb even if you remove the clamp. The pressures, over time will prevent you from pulling that hose off even without the clamp. So, the process for removal will be to remove the top clamp and split the upper end, then you will unscrew the lower barb with the hose attached (with or without the clamp) and the split the hose from the barb after the barb is removed. Again. Everyone has their preferences. If the job gets done, then your preference worked. That is all that matters. Thanks for the views and adding to the numbers. You have a good day.
