Great writeup Rob !!

I am running hydro assist as well and I just did the mods to existing power steering pump and I definitely notice a difference. It feels like it has sped up alot compared to before, but sometimes still a little slow in tight turns. I drilled out the center pin and notched it like shown on this site: http://westtexasoffroad.homestead.co...rsteering.html I also am running a power steering cooler from an explorer. Works great and lets me run some extra fluid too...

You can ask around here and someone will have a dual groove pulley. I found mine locally. My 88 had daul pulleys, both the same circumference. One ran the air pump. Dennis

A quick update:

didn't manage to get the pump mod done yet, I'll need to replace my high pressure line out of the pump since its shot and I'll have to cut it to remove it.....I looked into what dennis was saying about dual belts and it turns out it'll be an easy mod for me



As you can see, I need to pick up the belt but I've got the dual pulley already. Must have been used on the rigs with AC, since I don't use my compressor right now(it's fried)

I also rigged up a skid out of some scrap 1/4" steel. It's sort of an odd angle I took the pics at, but it's level with the bottom of the housing and then comes up 45 degrees infront of the ram.

Yea, I think all the balancers and pulley for the coolent pump are 3 groove. So just find a dual for the steering, and your done. I also did it with my alternator, casue it is a 105 amp and had trouble when the fans kicked in. Also worked great. Dennis

Yep, first time I saw that cooler I was thinking it would really help if I was to use a Milemarker hydraulic winch (they only weigh about 65Lbs, probably w/o cable).
Still be interested to know if the high pressure pump is compatible with hydroboost brakes... if anyone knows?

Elliot, you figure a little tranny cooler would work also if it was hooked up to the low pressure return hose?

how necessary is a cooler over just more capacity

I have never had any problems w/ lack of fluid or everheating, but I've only wheeled w/ my hydro assist a few times.

This is probably the same thing, 1/2 the price, but will have less capacity: http://www.noid.org/pscooler/

I've got a manual trans and an auto radiator, thought about cooling my ps fluid in the radiator, but don't know how well those worked.

the only thing you have to watch out for with trans coolers is that some aren't set up for this kind of flow. If it looks like a radiator, it's no good, if its a big 'S' with fins attached, it's perfect for this.

BTW - got to try this out on a real wheelin' trip today, LOVED it. This ram was one of the best investments I've made on the heep...

just a quick update. I did the dual belt mod, with two new matched belts. Also did the hi-pressure mod to the pump. Feel absolutely, positively....no difference

Not saying these mods don't work, just that they didn't do anything for me. Just an FYI...

Well, the dual belt is only going to keep the pump from chirping when the single belt slips.
AGR makes a high pressure pump, but don't know what it accomplishes that the modification doesn't.
