Ran tits for about two hours and then no workie. Did the mods per Westtexas and now it obviously doesn't. Was not running hydro assist yet, just tried to bump up flow so i could turn. Want to go w/ assist but not if this keeps happening.

Uhh ya your pump is SUPPOSE to crack in half! Ya that's cool, just throw it in and run it dude.:rolleyes:

Hey ding dong, if you don't have any tech info to offer don't offer anything. Pissed about shit breakin i don't need your lame ass comments and rolly eyes. What i need is advise on how to prevent this.:flipoff2:

hey ding dong, if you don't want some sarcasm then don't put it in your question. You being pissed about your shit breaking is your problem not his. :flipoff2: oh yes how to fix this get out your checkbook LOL

Don't you remember the thread about NO WHININ'?
That said it sucks that your pump blew but you took the risk when you modified it!Later:smokin:

There was an earlier post about those "suggested" mods to bump up pressure. Other people also chimed in about failures when using those mods. Seems to me like thay might be a little too risky. Maybe you should start a "Who used the Lakerats mods and blew up" post.

I'd be interested in seeing the results. Plus if it was bad then he might reconsider posting them on his site.

I just did this mod today also, so your results concern me... What exactly did you do to the pump??? Did you drill out the fitting fo more flow, or not?? Did you remove the shim on the end-cap, and add washers, or just add washers, how many washers did you add??

I added two stainless #4 washers, and left the shim as i felt it may act as a seal also. I did not hone out the fitting, just increased the pressure. It has run great all day, although i notice my belt slipping a little now, i guess it demands more from the belt to make more pressure???? I will have to check that this weekend.

Let me know what you find out...

Good Luck!

Here, search this, Looks like a search could of been a help!:flipoff2:

First i will reply to the people that took it upon themselves to be idiots. This is a tech section not a " come over here and show me how little you really know about everything " section. As for my breakage, why yes, you are correct it is my problem but i still have the right to be pissed. Do us serious people a favor and just keep your critisism and lack of knowledge to yourself. I'm not whining, i'm trying to keep this post serious.

Now as for your question, i didn't have a shim so i added two (2) #4 machine washers and removed about an 1/8 off of the limiting stud. Drilled the hole to the recommended size and notched per instruction. I guess my question would be if all i'm doing is increasing flow why did it break? What is the difference between AGR's pumps and the mods we made? And do i need to modify the pump for assist or can i leave it stock or should i buy an AGR?

Well since I'm not serious and I have no knowledge of anything I guess you wouldn't want to know that a stock pump should work just fine for hydro assist!

And My God man I dont' know why you are so pissed! You posted in the linked thread above and there were lots of people that said they blew their pumps by doin EXACTLY what you did! So stop takin it out on us because you didn't listen when other people talked about problems din this.Go have a beer or six!

i is too stoopid to no n-e-thin so i wunt say nuthin abut a kewler or the guys i no that have great info and have done a bunch of them so you could get some usfull info

That is exactly what mine looked like when it cracked! I only did the mods for more pressure not more flow. My pump had NO shims but the cap piece was not completly threaded in and it had been locktited in that spot. My new one was the same so I just threaded it in more and locktited it there with no washers inside either.

From Matt's site:
WARNING: I highly recommend doing these mods a little at a time until you've reached a level that you are happy with.
Maybe it would be good to try it one step at a time? I'll be running mine with a stock hydro boost pump till I see how it works feeding hydro boost, PS box, AND hydro assist. If it needs more, I'll apply the changes suggested by Mat one at a time to see how things work out.

It sounds like you went down the list and did everything. Step 3 and 4 are about pressure. Steps 1 and 2 are about flow...

OK restart, reset. Thanks to those that helped. Sorry to those i offended. To run hydro assist, do i need to increase flow or pressure, both or neither?

My Hydro Assist works great with no modifications to the pump. Matt at WTOR ported the box for me. I have a saginaw pump and a 78 Ford box. I can turn my 38.5 SX's on pavement, sitting still, with the ARB locked, with one finger. Dont see why you would need to mess with the pump as long as it is in good shape.

I think that Matt does excellent work and i think the fuck up was my own. I should have followed steps 1&2 and not done all four. Will continue with assist.

damn good question since I have not modded mine yet but I do have the ram. What does the AGR pump have different? I would like to run a bolt in pump - on my serpentine ford 5.0. AGR does make a ford pump, is it worth it? I don't have wheels n tires on mine at the moment so maybe it will be different but as it sure does not turn any easier with the ram..

I do have new ball joints etc but ?

Sorry to all that have had problems.

I'm going to change the tech article to stste that only one washer needs to be installed. This should keep things safe. What the problem seems to be is one of 2 problems.
1st problem is that these mods were not meant to be done at the same time. The flow mod is for people running hydro assist and are having problems with the speed of their system. ythe pressre mod is for people that just want to get more out of their existing setup. Personally my hydrpo assist works just fine with a stock pump, but some of my customers have had problems with their steering being WAY too slow. That's why i posted that mod.

2nd, the pressure mod seems to be causing the other problems. Comes to find out that depending what the manufacturer had to use that day for material, the washers are different thicknesses. And i'm sure if you use 2 washers that are twice as thick as the ones that i used to test with that it could cause MAJOR problems.
Personnaly i've never cracked a pump, but i have grenaded a box and blown parts across the parking lot. Also this mod is not needed for hydro assist. I have made sure that the fitting is screwed down on the piston on the pumps that i have modified for customers but have never added the washers and increased the flow.

Again i'm sorry if youve had problems and please let me know if i can help.

So in a nutshell i can use my stock un-modified pump with a ram that has a 2"bore and an 8" stroke? And if i decide to increase flow all i need to do is drill and notch the one piece? The flow mod should in no way crack the pump correct?
Thanks for the tech article. I did the mods a few months ago but only have about two hours driving time on the vehicle.

Yes that is correct, and even if it feels slow to you then just make the drill and notch in small increments until it is satisfactory to you. Make sure that you drive it in low and high speeds because if you drill out the fitting too far then it has a tendency to get a bit touchy at higher speeds

my freind talked to a agr guy who acctually came out and said that their pumps are no different (in acctual WORKING specs) than a 91+ ford pump..

I guess 91+ are a different better pump??

what do you guys think of this?

Instead of drilling and tapping the front cap would it be ok to weld an aluminum hydro fitting onto the front? Would the fitting work with a hydro line or cause probs?
