Hi Team,

I strongly suspect that my 940 (2.0 T SW from '97) needs a rebuild for both the water pump and the steering pump.

I searched in my local area, Atlantic Canada, but nobody seems to rebuild this stuff.

I could buy an original Volvo water pump, but no chance for the power steering one (discontinued).

An aftermarket steering pump, I am not sure they are any good really, during the last years, even the so called genuine Volvo parts have gone downhill with regards to quality, so this is why I'd rather prefer to have the original ones rebuilt, which basically means changing their respective bearings.

Do you know anyone who offers that service in NA?

Also, the power steering seems to be slightly misaligned, I cannot say why until I disassemble it, but am I right to assume the only reason of misalignment would be the bracket holes been worn? I doubt it, because that pump has never been touched in 26 years, but not sure what else could cause a misalignment.

Thank you!
Alessandro

did you search the part number on Google??

Sure I did, but not much can be found, and always the same stuff.

I will see in Europe, it is easier there to find shops that rebuild any kind of automotive parts.

Thank you,
Alessandro

Hi Metallo,

How the pulley could be slightly misaligned? What happened was that most mechanic / diy'ers didn't know that they have to loosen the 13mm bolt at the pump's pivot (this is hidden way below the pulley) and also the 12mm bolt at the adjuster's pivot (this also hidden behind water pump pulley) when replacing / adjusting the belt. Then tighten them back afterwards.

Most of them just meddle with the adjuster's lock nut and long bolt.

Over the years both pivots may have gone worn unnecessarily and cause pulley misalignment. You'd have to check which of what happened. You might have to replace the pivot bolts, pump mounting brackets and/or adjuster bracket to correct this. Putting shims may be helpful but damage is already there.

About the water pump just replace with new. You won't find any aftermarket sleeve bearings for it.

About the steering pump if its not leaking fluid just continue to use it albeit the increased bearing noise. Search for rebuilt ones from eBay or low-mileage ones from Pick n Pull yards.

My 940t has 313K on the clock. The power steering pump was misaligned enough that it created a lot of belt noise. I stacked some fender washers between the bracket and the block to bring it back in place. There is probably a much better solution but that was mine.

Hepu makes a quality pump and they are available a number of places.

Randy,

Your solution sounds to be effective to me.

How long ago did you do that? If it is still working, that is the way to go.

To be honest, the leak I see in the steering pump appears to come from the suction hose:

Since I need to remove the pump to re-align it, I was thinking to have it properly checked, but it appears this is not possible here in NA.

Thank you,
Alessandro

Checking my records it would appear that I added 5/32" shims (fender washers) on the front mounting bolts of the power steering bracket. That was in April of 2018, 38,000 miles ago. However, I went back not long after that and added additional washers because the first fix didn't end up being enough.

I did not have to remove the pump. I just loosened the bracket as much as I could and then removed one bolt at a time and slipped the washers into place before tightening things up. I had to increase the length of the mounting bolts associated with the washers to get enough of the bolts into the block to feel comfortable that they had enough penetration.

I think I would clean up that pump with brake cleaner and snug up the clamp on that hose and keep an eye on it to see if that was the problem.

Hi Randy,

Today I removed the bracket, without disconnecting the pump from the hoses, I hooked the pump up somewhere so that its weight (it is light anyway) does not damage the hoses.

The bracket is now in the degreaser so tomorrow I will be able to better see, but at a first glance, it appears that the front holes are bit larger than what they should, which in my opinion could have causes the bracket to move against the block, and since it is made of aluminum, it is possible that the front side of the bracket is now less thick than the back side.

Tomorrow, I will measure and compare the tickness with a digital caliber, even 1mm difference could cause the difference you see in this image.

Now, since the bracket is made of aluminum, I would lean to use aluminum fender washers, as I do not think stainless steel would do any good to the bracket, because stainless steel is harder.

Thoughts?

Alessandro

It has been a few years, but I don't remember that the bracket on my 940t was made of aluminum. Memory tells me that it was steel.

That is what I thought too, but when you lift the bracket is very light and also the color suggests it is aluminum.

If you look at the color of this refurbished one, it is the same.

Do you remember if you used steel washers or aluminum ones?

Alessandro

That does not look like the bracket that is associated with my power steering pump. I believe you have a completely different setup than my US spec car.

I cleaned and measured the bracket, both its thickness and holes, everything looks good, and consistent on each side.

I am now going to try to reassemble and see if I can spot why is misaligned.

What is the torque for the M8 of the bracket? 24Nm?

Alessandro

Hi,
Jeepers, you might be showing your age! 🥸

Yes the misalignment started or remained throughout the 240 years so I do not doubt it’s not your imagination about the alignment.
Replacement of sagging bushings helps the 240s.
Several people purchase aftermarket polyurethane bushings but it all should have been better from Volvo.

As far as rebuilding pumps that has been blown into the weeds by rebuilder competitions and recycling efforts.
Both these pumps are simplistic in design and operation. So I understand your questions of kits but those kits being provided to a limited population of persons who would do it anymore is the answer.

The power steering pump was probably made by Saginaw in Michigan.
Thirty years ago I showed films in my classes where one machine bored the housings at the rate of 600 an hour! Trust me, assembling is not all that far behind when needed. Normal is about 20% of that.
Most car manufacturers source their products from a world wide base.
The world is a global enterprise for absorption or consolidation as Continental Elite series bought the GoodYear GatorBack Quiet designed V belts.
The slanted rib made it quieter upon entry into and exiting a pulley.
They may be using the GoodYear rubber formulation in the poly series serpentines.
Gone from the market place now.
I cannot find them except in old stock today.
I’m still trying to follow that paper chain.

The only way you can repair them is to get yourself in between the part makers and the rebuilder as they the rebuilder did.
Unless you can substitute a common seal arrangement you have to make them yourself.
Same goes for the main bushing or the grooved plain bearing that fits the shaft of the power steering pump.
Water pump bearings go bad if ran too long with internal coolant leakage. Not noticing drips from the weep hole or noisy operation is the final death. They have rollers or balls and not repairable.

Save the core and stock up.

Dear metallo,

Hope you're well and stay so. For a re-built power steering pump, see: https://www.partsgeek.com/catalog/1995/volvo/940/steering/power_steering_pump.html . A-1 Cardone is supposed to be a good product. That said, I've never installed one of their re-built pumps.

For replacement water pumps, see: https://www.partsgeek.com/catalog/1993/volvo/940/cooling_system/water_pump.html ,

The Volvo brand water pump is available at: ttps://www.fcpeuro.com/Parts/?keywords=271975 .

Power steering pumps can go out of alignment if the belt is over-tightened, and then many miles elapse. The power steering pump mounting is, unfortunately, NLA.

Hope this helps.

Yours faithfully,

Spook

Hi All,

Thank you for your input.

The steering pump you have linked at partsgeek and Cardone, I had seen them previously, but they are not the same I have, which is: P/N 8251726

It is hard to find it indeed.

With regards to the Hepu water pump, unfortunately, not everyone had them last longer than 2 years, which tells me they all aligned.
To me they all seem the same quality, even Graf, if they cost 40$, you cannot have quality in there.
They all sell the same stuff, sad :)

So there is nobody who really service the genuine ones here in NA?

Guys, I am old school (as probably you too), it is hard to accept this, and I simply cannot accept to buy the crappy stuff it is sold nowdays.

Even the so called genuine parts by Volvo are no longer the same, I have experienced this myself.
