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.
It would work, but, as previously stated, that is a lot of drag.  The ram has to circulate fluid from one side, through the hoses, to the other side. 

And yes, valves are available.

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.

Where did you buy the cooler and how much? Thanks much

Yota4life-

I bought the cooler from PAW 818-678-3000

It was 27.95 and came with the low pressure hoses.

It is a Hayden Part # 401 which you can also get from JEGS and SUMMIT.  :beer:

The hose's from Surplus Center come with ends on them, they only run about 8 bucks too.

that reminds me I need to get a couple a spares. After the last trip I noticed on of my lines had been getting :bumpinbutts: bettween the bumpstop and one of the u bolts and got tore up pretty good. Those hoses just arent something you can ask "Hey you got an extra hydro hose?" out on the trail. You'd be pretty much screwed.

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?

Tapped the hole too deep, I did the same thing and yes it hit. Easy fix, pull the fitting and grind the threads down and reinstall, keep doing this till the fitting is tight and will clear the gear

Turn the input shaft to the left until it stops. Now remove the 4 input shaft housing bolts.
keeping the input turned to the left helps keep it together.  Mine had some water contamination and while spraying it out with brake cleaner I turned the input to the right a little to far and OOPS! damn ball bearings went everywhere when it came apart! only way i found to get them back in was to take the 2 piece tube out and work them back in until full, then using 1 of the tube pieces and turning the assembly up sideways as to get the tube level horizontly put the rest of the bearings in and slowly work the other half of the tube in and secure it. wish i had counted all the ball bearings but forgot, hope i found all of them!

great write up on the box!

I wrapped my hoses with heater hose so they are protected. I did this after wrecking one hose. So far works like a champ.

Post up when your box fails. I predict the balls will get pulverized and leave you with no steering.

daaaaaannnng! pulverizing my balls is not good! maybe, maybe not!

the tube i refer to limits how far in and out the balls can go. after i figured that out i believe after i got them all in i'll be OK. we'll see. it was a high mile box but it was tight and had no leaks. i'll post on it later.

i didn't read it in this thread but is anyone running any type of sealing stuff like teflon tape on the threads of the fittings and ram?  i just got my box tapped and was wondering if it is needed or not.

You shouldn't need t-tape. NPT fittings are taper seat fittings so they seal on themselves. If you throw t-tape on, it shouldn't matter.

Im having a problem with the restrictor. I cant get the bushing to come out. I was slamming it hard on a steel table and couldnt get it to budge. Any pointers?

It should just fall out!! :dunno:  Miine did. But after drilling it out, it made my pump squel really bad at 1000 rpm's and higher. Plus I would have to have the rpm's up for my ram to work!! :dunno:  Try it in stock form first and see how it works. I know if it doesn't them you'll have to take it apart and bled the system again.  Also,I have my modified one still I just have to remember where I put it!! :smack: So if you can't get the bushing out you can have mine.  Just throw down a few bucks for shipping. :thumbs:

Well i turned it upside down and stuck a rod in there and hit it with the hammer and there was a little peice that had 2 holes in it and that just broke out. So i might have just ruined it but i still cant get it out. I might take you up on that Tice

Shoot me a p.m. with your address if you want it. I haven't had a chance to look for it but I think I know where it's at.

This is an in depth layout of how I have drilled/tapped Toyota IFS steering boxes for Hydro assist as well as a simple mod to allow your pump to keep up. I was able to get ahold of a box (thanks toecutter) so I could show a bit more detail than my original thread on just setting up my system. This is intended to give a bit more info on the time, tools, and ability needed to do this mod. I was nervous about it the first time but once I got into it, I was upset at how difficult many people made the job sound. If you want to give me $75 to do your box, that's fine but this is not about me making money, it's to show that it can be done easily by most people. It took me about 2 hrs. from start to finish and that was with taking all the pictures. So if you have the ability, a bit of patience, and don't have the cash to have someone elso do it, try it yourself.

And this is the rest of setting up my Hydro assist system for cheap.   http://board.marlincrawler.com/index.php?topic=4699.0

It sounds like you have a 3rd gen pump and that is how the restrictor is. That is what you were supposed to drill out but you broke it instead.
