Has anyone done this set up, but with a late model Sawginaw pump? I am wondering if I will have the problem with cavitaion. The rest of my system is the same as most of you. I just happen to have a 4.3L vortec in my truck.

It should be the same. You may have to had more capacity to your resivour but other than that it should work.

When I do my conversion on my 82 that has a Vortec with the Saginaw pump I will let you know what happened. I will ad a cooler to the return line to give some more capacity. I am also doing this to a 92 truck with Toy pump. I will enlarge the restrictor as mentioned in Hydro Assist On the Cheap. I will ad a cooler, but wondering if I can ad a secondary reservoir instead of brazing on an extension to the Toy Res.

On the Sag pump, you can open up the restrictor as well. For your res. you can do a secondary canister, only down sides I could see would be it will need to be a flow through as a T in the line won't force the fluid through it and also it's 1 more thing to mount under the hood.

I think I will need to seriously consider running more capacity with my Sag. A few years ago I was ditching the man when I was wheelin where I shouldn't be at 2 a.m. I was haulin down a twisty fire road and that alone made my fluid boil over.

I thought I would say that I just used this to port my box, I am wheeling a nissan so I gotta figure out how to open up my nissan pump. Anyways, this worked out great. I used a magnet to get most of the pieces, it worked gerat right after the hole was drilled.

Has anybody noticed an increase in internal box failure with hydro assist? The internals of my box exploded after 3 trail rides since it was ported.

So I succesfully finished the install on the 92. Worked out great. Bled the system with the wheels up in the air. Because I made the factory reservoir 3" taller I had to remove the EGR valve bracket. If you do this remember to put back the small bolt that held the bracket in or else you will have a idle problem because of a vacuum leak.

Now I am going to do it on my 82. Does any one have a source for a bolt on collar that goes on Marlins' tie rod so I can weld tabs for the ram.?

I don't know that this is quite what your looking for.  Maybe worth consideration.

I just welded tabs on the tie rod.  Purchased my tabs from this place.

Something like this.

They just don't make it the size that fits Marlin's tie rod.

Surplus Center is on the net. They are pretty quick about shipping and it'll still be cheaper than most kit form hoses.

Here is a picture of the modified P.S. reservoir and the cooler I installed on Rokcrawlintoy's rig. No squeeling and it stays cool.

I've got an IFS box that I bought second hand, pre-tapped...
when looking into the empty box, it looks like the fitting in the "TOYODA" will be hit by the sector shaft gears as you turn.
is that a problem for anyone?

So, how many of you would do this mod on a daily driver?  Would it be to twitchy to drive on the freeway? 

Any thoughts as to how one might be able to turn the RAM off?  Just throwing out ideas here, but could a valve be installed somewhere that would essentially stop fluid going to the RAM assist when you were driving on road.  Then, just flip the switch and start crawling.

This of course may not be practical or impossible... but I would appreciate feedback if anyone has any.   :yesnod:

You would still have to fight the drag of the ram pushing fluid back and forth in the lines. I think that is how it would work at least. I don't know if I would do it on a daily driver after how mine turned out. I was not able to drill my restrictor so it is pretty slow. I have had a few hairy incidents with hitting curbs while hot rodding around corners and coming close to entering the neighbor's yard.

If you still have control you aren't going fast enough

Why were you not able to drill out your restrictor?

Anyone think this idea would work...





In effect, would isolate the RAM unless the valves where open, and would allow the RAM to run in a closed loop when valves where shut which would allow the RAM to move freely against the stock steering box pressure... almost like a steering dampner if anything.

Just seems like this might be a good idea for a daily driver.  No change on road (valves closed) and full ability to crawl with low PSI, etc off road (valves open).  Off course this assumes such valves are even available.
