I purchased the one 8.6cah12b pump from you and so far it has worked great. Question is I just tried the detergent siphon and I can't get it to siphon. I purchased the blue soap tip and tried everything. The real curious thing is normally the motor runs in idle mode and drops down when I pull the trigger on the wand. Now it idles when I pullnthe trigger and drops down when I release and it appears to be putting backpressure on the pump.

Answer
Soap siphons only work when the black tip is in place. Your pressure washer-safe detergent needs to have a watery consistency- if it's too thick (like dish detergent) it won't be picked up by the water rushing by.

To get the siphon started you may need to lift the level of the soap container. Once the siphon is established you should be able to keep it close by, at ground level.

Here is a link for more information about How A Siphon Works.

I'm sorry, but the only blue nozzle I'm familiar with are in the Second Story Spray Kits. They constrict the water supply so the water shoots higher. Since your pump and motor are directly connected they will affect each other.

OEM Technologies pumps are made by Simpson- you can contact them at 877-362-4271 if you have questions about your pump's performance.

I have a pressure washer with a 5hp Honda engine. The drive shaft measures .875. Bolt holes are 2-1/2" Which replacement pumps will work for me?

Answer
That would be a 7/8" shaft. Does the pump come out of the bottom of the engine, under the pressure washer? Does it have 3 bolts holding the pump on?

Will this model fit a Simpson MSH3125?

will pump Model 86cah12b fit a troy built powerwasher model 020242 rev.4

Answer
I'm sorry, we don't sell Troybilt products, and there isn't a cross-reference of all brands and all pumps available- I don't know if it will fit.

OEM pumps are made by Simpson, so you may want to call them at 877-362-4271 to discuss the bolt pattern and shaft size you need to see if they have a pump that will fit.
