I recently had a Saginaw power steering pump failure on my #ETCGDadsTruck build. In this video I tear down the faulty pump to see what the issue was. If you’re curious about how one of these pumps comes apart, what damage to look for during inspection, and how to reassemble it, check out this video.

I grew up in Saginaw. And I spent many hours inside Saginaw Steering Gear where that pump was made. I watched those pump parts being machined, and the pumps being assembled on the assembly line. It was a very high volume operation. Of course they did not come from the factory with that pretty chrome plating, they were all black,

I was working on an 82 nova which had the motor replaced from a caprice which, unknown to us at the time, the previous owner had installed so after the customer kept bringing us the wrong pump i decided to look at a pump we had laying around from a 90s pick up. Long story short i ended up swapping the high pressure outlet and viola. This just goes to show you sometimes these scenarios like this happen and videos like yours become the solution! Dont stop making videos bro and thanx !!!

Ah, I finally know what happened with the pulley. I hope the short time the distorted pulley was being used inside the truck did not cause much damage to the pump. Now, you have a better cooling system for the pump, as well. Thanks for the inside look into the bad pump. I'm sure you could rebuild the pump, but having a warranty really saves time and money. I was showing one of my sons, Gabriel, the process you used to determine the fault with your power steering. Mostly, I wanted to show him my interest in watching your videos and how I wanted to do my own repairs, once we get back to the States. His real interest is Architecture. So, there you go. I feel better now. Great job. Jeff

Pressure is created by stress upon a fluid. A flowing fluid when restricted will create a pressure in response to the restriction. But you can also create pressure on a fluid in a static cylinder by putting mechanical force on it. I.e. static vs dynamic pressure

Cool, always wondered how power steering pumps worked. My car uses an electric one, I asume that instead of being driven by a pulley, it's driven by an independant electric motor. Really tight tolerances there, no wonder it failed due to the faulty pulley. I hope none of that metal shavings went to the rack though. Great video Eric, as usual! 👍🏼🙂

Cool. I have a nearly identical pump in a '70s Cadillac that's good, but leaks around that big O-ring that encompasses the whole pump. I temporarily fixed it a few years ago with some JB weld smeared around the seam, but it's leaking again and time to fix it properly. Remanufactured parts are often hit and miss, so I wanted to keep the original pump, but I thought I'd need a press and some special jig to get it apart. I'm quite thrilled to see it's possible to do with a hammer.

8:00 did you put the stator ring in upside down? Looks like the 3 diamonds are facing down? These pumps internally are the same as fitted to Holden Commodores albeit remote reservoir and a few less orings. Best way to get that rear cover on was to stick it in the press and use that and a big socket to hold it down whilst I wrangled that clip on. My first pump was a nightmare, they dislike high RPM, heat, etc so. You didn't remove any orings from the bore also to remove the stator ring, did it just slip past them(trying to gain insight into the design progression)? Conveniently this general vane pump style only really leaks from that rear plate oring, $1-2 fix for most models. Enough to pass inspection. Some interesting design notes, on the back of those black diecast bits(i think they're called manifold plates?) are 4 tiny pads which are surface ground first before doing the other side. Saves a lot of time and grinding wheels. Wonder if you could rehone those faces with a sanding plate? Piece of thick glass and progressive grits, the spring could take up the slight reduction in height(which it does anyway, removes the tolerance stackup issues)

Had one of these on my P30 motorhome. I pulled it apart and smoothed the pump surfaces on some emerycloth on glass. Smoothed the vein edges the same way. Then, replaced the orings and cleaned everything. Pump was was $900 new from dealer. Got a rebuild kit from local Carquest about $30. Still worked with no leaks after 50k miles. If the spring has no pressure when you remove it then the pump is worthless, don't bother trying to rebuild. the spring keeps the receiver plate tight against the veins.

I just took one of these apart for my 1998 K1500. I discovered that you shouldn't use the hammer method to put the pump back in the reservoir. I accidentally tore the o-ring doing it that way. Instead, just gently pull the two together using the two nuts on the back. Just alternate between each one to evenly pull the pump and reservoir together. For me, I used a deep impact socket and just twisted the socket with my hand, no ratchet or wrench, and use the socket to hand tighten each bolt. Going about a half turn on each nut alternating back and forth.

And that's exactly why the pump worked when it was cold, but not when it was hot. The grooves that your fingernail would catch on will get bigger as the pump heats up -- and with such tight tolerances, where even those tiny grooves cause problems, making them larger by any amount will cause the pump to get worse. Precisely the symptoms you were seeing. Cool analysis!

It's funny how every time I do an unusual job, there's one of my KZbin subs that end up doing the exact same thing at the same time! 😂 Great vid, Eric! This is a perfect example of how things aren't built like they used to be. As I mentioned in a previous comment, I recently dismantled and rebuilt my original OE power steering pump in my '86 Grand Marquis with 268k miles on it. Pump still worked, just had a few leaks. Bought a Gates seal kit on RockAuto and installed it. Anyway, what a difference in construction compared to that Saginaw! Mine had springs and slippers with leading and trailing edge - 10x bigger and stronger than those vanes in there. Also 10x more frustrating to get back in place! Also, my snap ring was much thicker with a larger circumference, and much more difficult to extract. I wanted to keep the OE unit, so I dealt with the frustration of this overhaul. I wonder if a rebuilt unit at any parts store would be built this same way? I think I know the answer to that, so I didn't dare take a chance. It just amazes me that there were metals available in 1986 that could withstand this repeated cycling for decades on end without failure! Too bad automakers don't care to use these high quality components in ANYTHING anymore. Imagine how many cycles each spring has seen! Just at idle that thing is spinning at 6-700 RPM. There's probably 8,000+ hours of runtime on this engine!! Amazing. I'm going on day 7 of trying to edit that mess of a video. I need a new computer ... or someone who knows how the hell to fix it! Even the people who built it (Apple) are no help! Everything works except my pictures and video editing stuff - slow as molasses in January ... through dial up internet! $4,000 for the new setup I want, so that's a big holdup ... 🤢

for that power steering pump, seal kits are available for very cheep (28401490 is $18.99 at O'Reilly auto parts at the time of this comment) and the most common failure for that pump is the seal on that plate with the clip you removed with a punch. That seal separates the high pressure side from the low pressure side. That valve that you took apart is also available for around $38 for an oem acdelco part also, instead of 2 c-clamps, use a vice or arbor press, it's much easier

You wouldn't believe how hard it is to get a good replacement pump these days. I've had 3 of this exact style pump from different manufacturers (including acdelco) be bad out of the box or within 50 miles and several other ford styles as well. In both cases wound up resealing a used original (dodge or gm) part and have no trouble. Aftermarket steering parts overall seem to be generally terrible these days.

Yep. :-) People think pumps make pressure. They don't. Pumps make flow. Pressure (as you said) is a resistance to that flow. Some fun facts. Hydraulics is like electricity in most ways. Think of electrical current as flow, and voltage as pressure and will be clear. So, for pipes/wires, as the current/flow increases, so the pipe/wire must be bigger. As the pressure/voltage increase the pipe wall thickness/wire insulation must increase. For a constant flow/current, as the pressure/voltage increases, the resultant transmitted power also increase (and visa-versa)... Check valve = diode, pilot operated check valve = transistor (or relay), accumulator = capacitor, filter = inductor, flow restrictor = resistor, intensifier = transformer (sort of), pump = battery... Fun!

Eric, I am wondering if the thinning of the fluid due to overheating may have contributed to this failure. What is the maximum temperature rating for a power steering fluid? Since the back plate is just spring-loaded maybe you could help it by removing a bit of that scoring with some stone. Btw, I enjoy these disassembly videos the most cause I believe understanding how it works and what's inside is the key to the success....

The fluid seemed to run about 170º before I installed the cooler. I don't think that was excessive. See last weeks video linked in the description. I think the bent pulley was the root cause. In my experience, there is no fixing machined parts with sanding or filing by hand.

Hmm I like that chrome or whatever finish on that pump. Like have that on my 85 s10 2.8 would go really well with my chevy orange block and black pulleys 😮

I had a van a few years ago with a noisy power steering pump. One day the power steering completely failed and there was no power steering at all. I took the pump apart and found that the spline was stripped on the shaft inside the pump.

That scoring was most likely caused by the pump ingesting debris such as metal chips and dirt. I recommend flushing the lines and rack before installing your new pump. Had the pulley been the culprit, I would think that it would have caused a bearing failure or bent the shaft.

I've just rebuilt the power steering pump on my 1991 Jaguar Sovereign XJ40 and while the outside of the casing is different, with a remote reservoir, the inside is exactly the same.

Was thinking of using dexron6 or redline d4 I switched to psf but original fluid looked red but very dirty I'm getting some noise now (bled air also) think of using atf any suggestions?

The pump creates a flow, but it also creates a high pressure zone between it and the valve. The valve serves to restrict flow to maintain a pressure differential across it and the vent. This type of pump is pressure controlled. They also make pumps that are flow controlled and will drive at varying pressures to try and match a guaranteed flow. Did you have access to get a sanding block to the back plates of that pump mechanism? If you could have sanded those groves out I bet you could have made it work again. it looks like that back plate could vary in position for a varying thickness pump assembly. In basic terms, that scoring you saw caused excessive leakage. Those metal fins aren't the greatest at sealing, but because we contained the leakage paths, they don't have to seal perfectly, just enough. The grooves served as too much seperation though and allowed for excessive leakage.

Yup, that thing was fried! Cool vid! Now I want to go digging through my junk pile & strip 1 apart... purely for the science of course! (Not because I like tearing things apart or anything).
