Yes, they can be rebuilt, but unless you are a professional hydraulics mechanic, it isn't worth it. Rebuilt motors generally don't last very long. I have rebuilt some and they require a special socket to get the bolts out...look at the bolts that hold the face on... The replacement from Grainger...

You can get a replacement motor (it's not a pump) from Grainger. Part no. 4TY85

Stainless steel tubing from the equipment room to the bays is the best way to go. I did mine about 10 years ago and haven't had a single issue with them. 3/8" tubing is what I use for the hp lines, 1'4" for the low pressure stuff.

Most tunnels and autos have a "low hydraulic level" shut off. If you keep your hydraulic fluid level just above the shutoff level, then there shouldn't be that much fluid loss. This would result in less fluid coverage of a vehicle when a line does break.

A lot of the Specialty parts are available from Tri-Valley in Ohio. 800-323-8915 A lot of the parts are standard "hardware store" parts.

Wishing you all a very Merry Christmas and a prosperous and Happy New Year. May 2012 bring in more jingle with less kringle...or more....

Years ago, when I was a manager at full serv carwashes, I trained the best personnel to be future managers. Worked with them daily to make sure they knew what their responsibilities were. Keep in mind that as the manager goes, so goes the carwash. A sloppy manager with no eye for detail will run...

Mine does 1 or 2 presoak passes, depending on which package the customer gets, then on the wash pass, it mixes in some presoak with the hp pass. Doesn't really do much other than a little show for the customer. Also have some presoak chemical mixed in with the undercarriage spray.

Sure, my hp wash pass has presoak mixed in with it. Doesn't everybody's?

I have replaced 2 Cat 310's with Armitsu 318's about a year ago. They do run quieter and have not had to do anything to them as yet. I get them from a local car wash supplier here in Houston.

I have used Hypro pumps but find them to be more expensive and not as durable as a Cat or Armitsu pump.

Since you are in Texas (Austin)? call Sharon Wadsworth at Midlothian Insurance in Midlothian, Texas. She always gets me the best rates for my business, my car wash, and my work van.

I would suggest the 24vac coils.

washman, depends on which coils you get with your valves. You can use either 24vac or 120vac. Let me know which ones you get and I will be able to tell you where to plug them in. You have both on your Millennium (24vac and 120vac)

Washman, when testing your Cat3535, don't forget to turn on the "stop" light to open dema valve. If you don't you will deadhead your pump.

The best changeover is using 2 1" Dema hp solenoid valves. The motorized ball valve uses a small 24vac solenoid valve to shift from u/c to the gantry. Usually the 2 allen screws that hold the solenoid valve in place will strip out and allow air to leak. Get the Demas from KR. It will take a...

"Inexpensive stainless"...isn't that an oxymoron?

Typically, on a properly installed Futura system, there is a N.O. solenoid for each function, ie; FB, Tire/engine, H.P. etc. If your brushes are weeping when you open the valve, it is doing what it is supposed to do. Try installing a N.O. solenoid velve tied to a thermostat. You will have to...

I found a product called "Fluid Film" from Eureka Chemicals in Cal. Been using it for several years now on anything that moves or can become corroded. Seems to work very well.Use it on my tie rod ends with good success.
