    CAT 31DS Pump issues

    The serial number is the date code when the Cat pumps are built. I'll see if I can find the pump I have that is a 31DS. The pumps at my car wash have a chrome head, they were made in 1982. So the 31DS with a brass head had to have been made before that.

    CAT 31DS Pump issues

    Try this, disconnect the soap and wax lines from the pump and plug the ports and then run the pump, if the pulsating go away then you know the problem is in the soap and wax delivery side. Another thing you can try is to connect a city water hose to the pump water inlet and see if the pulsating...

    I live 150 miles from the Canadian border so we see a few Canadian coins every now and then. None of our Slugbuster II coin acceptors will accept them, they are rejected. What kind of coin acceptors is your guy using?

    vac nozzles

    Over the years I’ve tried just about every vac nozzle there is. They either stole them, took them off, we tried riveting them on the hose and they cut the hose just above the vac cuff. Now we use a VAA-20 vac cuff and I can’t remember when I last lost one...

    Hamilton Bill validator repair

    The STA is no longer supported by Hamilton, I believe it was around 2012 they stopped building the STA validators. The problem now is there are no parts available for the STA. For a $100 you probably got belts installed. The Mei/Cpi kit is a no brainier to install, I've sold a lot of them over...

    Cat310 Pump Pressure Adjustment

    If you use a 1505 or 1504 nozzle it'll give your customers the impression that they are getting a lot more pressure because of the narrower spray pattern.

    Cat310 Pump Pressure Adjustment

    That’s not a Cat 310 pump it looks like a 5CP2120 pump. The procedure for adjusting the pressure is the same, to increase the pressure turn the brass nut clockwise and to lower the pressure turn the nut counter clockwise. When I adjust the pressure, I have my helper hold the handle on the gun...

    I've repaired a lot of AE2612 validators. I just repaired 6 for one our Forum friends and they work perfect. Which Model Talos are you using? You should be using a T612-U3 model. They should work if your programing them correctly.

    After a Mei/Mars validator has been in service for a number of years the capacitors on the main board become weak and this causes the validator to have acceptance issues or not accept at all. You never know when they are going to fail It might be 2 year or 5 years. The same thing with LED TV's...

    Has anyone done a 5CP bearing replacment?

    That's what I do Greg. When a pump crankcase goes bad I don't bother with changing the bearings or the rods I swap out the crankcase. I've got one now that's over 40 years and it's got a rod knocking.

    Flojet Conversion

    Flo Jet G57 pumps are a good pump for foam brush. For Presoak and Tire cleaner I'd go with a Procon pump controlled with by MX-8 multiplexer. They'll last a longer than a Flo Jet pump when using high PH chemicals if they are installed correctly.
