-Oh no I picked a side-
But I assume thats using fluid type fittings and not air type fittings?
Fluid type fittings have curved inners where the air type have sharp corners.

yes, i'm refering to hydraulic type fittins, but yours statement on teh curved VS sharp corners is not always true. (good stuff yes, cheap stuff no, forged vs brazed.. etc)

So being realistic I have 7 fittings on my system. All the lines are 3/8". I think I am to the boiling point on this issue. My plan is to take the entire system apart and blow out all the lines to ensure nothing is in there. Take apart the ram to inspect for any FOD or damage. Inspect all fittings. I have a larger cooler with a fan that I am gonna swap in. As for the pump... I dont know yet.

wouldn't be a bad idea to change your return / tank line to 1/2". get rid of some back pressure.
what is the flow rating of your pump?
Maverick26

Ok I will try and do that too. Both my fittings on my cooler and res for the return system are 3/8th so changing the line to 1/2" might be kinda hard.

Are your fittings you used the standard ones?

I have been running a stock pump for ten years on the stomper. Over 6 of those years have been on full hydro with 53s. I took the pump off of an army cuccv with hydroboost brakes. The army only buys good american parts for its rigs. I suggest you do the same.
I used to not even have a cooler back in the day. I once reached over the frame rail to check belt tension and my arm touched one of the hard lines and it burned the skin right off of my arm. I then decided to install a cooler after that. Same pump tho. Stock and used when I put it on. Stock reservoir and all.
where are you getting your new pumps from, mav?:corn:

They are the Weather Head Coll-O-Crimp fittings like this one. You push them on and then crimp them with the machine. We use these on all our heavy equipment.

easy bud, refining your fittings is not going to magicly make pumps last. Thats splitting hairs IMO.
I have never seen someone fix a strange steering problem by upgrading fittings.
Thats like the stereo shop telling you need 4 gauge cable from your amp to your subs or it wont work right. (overkill)
Ive never seen a guy with a backhoe change a fitting to fix a whacked out hydro problem.

Well let me tell you, if you ever run into another one of those invincable US Army power steering pump you let me know!
The first pump that went out was on the motor when I pulled it. As far as I know it was stock cause it came out of a stock rig with only 69K miles. The second one that went out this weekend was from Napa. I plan to get my money back or at least try.

I agree 100%. I was not planning on upgrading. Just thought there might be somthing in a line.

you should get another good napa pump and see if it lasts unmodded.
Hey crash, any internal diffferences in the pumps off of trucks with hydroboost brakes?
The army even runs big hydro winches off of the GM steering pumps to.

fitting, no. hose yes. i have seen hoses come apart on the inside, creating a "flap" inside the hose, blocking it off.
Maverick26

I have 4 90* fittings at the orbital like everyone else and 2 90* fittings at the ram and a hard line that is bent coming from the back of the pump (pressure) to a strait crimp.

possible yes, likely no.
This is not likely on a new system with new hoses.
On an old backhoe or track hoe its a little more common cuz the hoses on the rear of the machine get beat on and kinked back and forth and the edge of a fitting could cut into the hose a little creating a little flap.
Possible, but not common.

-Oh no I picked a side-
They put out more pressure via the valve but the pump(internally) is the same like the vanes ect.

As long as they are fluid fittings then you should be ok there.

So if I do go get a new pump from Napa how many shims to I put under the end cap on the piston. My stock chevy pump had no shims under the end cap but the one I got from napa had 3. If you remove the shims it ups the pressure.
