    I have finished the retrofit of the MM1 to my 1998 Chevy 1500 and I am ecstatic with the final product. I have utilized the stock power-steering pump to power my hydraulics and I could not be happier with the final result. The 7.5 plow lifts and angles very quickly with little or no effect on steering performance. It was almost too simple. I bought a new pressure side power steering hose at NAPA, cut it in half, had them crimp on a 1/4" NPT end on each half. Then I bought a 1/4" male and female quick connect and affixed to each half of the stock hose. Two new 1/4" NPT X 3/8 compression hoses and another male / female quick connect the power steering pump to the in side of the valve assembly and the out side of the valve assembly back to the steering box and I am done. Now in the off season I just uncouple the quick-connects from the valve assembly and insert a short hydraulic hose with another male / female quick-connect and the power steering is back the way it was except for a 12" peice of hose. The only thing I have left to do is install the $200.00 wiring harness for the plow-side lights and I am ready to go. The stock Fisher harness was almost as expensive as my plow ($300). I am going to add the recommended ballast (400 lbs.). I am planning on using 40lb water softener salt bags and then using the salt in my softener as I need it. That should last through the winter.

    Very nice ..... Perhaps an inline filter on the return line a good idea.

    Interesting,
    How close to Chittenango/Cazenovia are you? I plan on moving my MM1 to my 98 GMC after my 88 dies and would like to see your setup.

    Just to update this thread, I am still using the above setup and have not experienced a single breakdown or loss of performance. We have had 2 ft of snow in the last 7 days and my truck and plow performed flawlessly. I first posted the use of the stock power steering unit to operate my MM1 in 2008.

    Congrats! My '88 just killed the power steering Saturday night with no plow "stress" on it :cry: Not sure if it is the pump or box yet, but it was full when I left the house but when doing my IL's, all of a sudden there was a groan and the wheel just about locked up. Not what I was looking for on a truck I was looking to sell in a week or so since I got a new one and just hadn't put the plow on yet.

    i notice you used pvc pipe for the extension on the steering pump . i have a similar home made set up but i used a piece of exhaust pipe so that air would help cool the fluid . the pvc insulates the heat . just a sugestion .

    That's great. I really like that idea.

    :mechanic:

    If you're saying you lost fluid, it's more likely a simple broken hose/rusted steel line.
