940 power steering pump bushes?

[Laney760]

Hi to All

Off the road again, three different reasons.

There was a clonk as I drove along the other day and the pas belt came off and obliterated the fan belt as it went so I limped to the garage without pas and not charging. Now the steering pump won't fully seem to tighten up. The garage did not have time to fully investigate, I am booked in at a later date but they seem to think that there should be bushes on the pas pump which are missing, probably totally deteriorated and somehow escaped past the lower engine cover to freedom?

The mechanic said that when the bolt which comes out of the bottom is tightened up fully it does not go all the way in, is this because there should be a bush there?

I have to order parts today, grateful for any advice as to what to order. Thanks.

I should add that my 940 pas pump suffered badly at the hands of a crap mechanic in Henley in 2014. I kept going back to that particular garage with a screeching steering belt and it turned out that because he could not work out how to fit the 3 belts he had used different sized ones and the strain on the steering pump from his fitting a much shorter belt meant that the big black bolt in it was totally bent and the pump was hanging off. My Volvo indi down in Wales were furious when they saw what he had done and they put it right. There is no way that the bolt this mechanic refers to now is some additional bolt which Volvo repaired my pump with is there?

I do not recall there being bushes on the hydraulic pump. I’ve attached a couple of pics of one of mine. They are only incidentally of the pump, but I can’t see any bushes. Just the metal bolts through the adjustment rail. I think the pivot is a solid bolt as well.

This is, of course, fairly crucial since it adjusts the tension of the belt that drives the water pump as well.

It is quite easy, and I speak from experience, to inadvertently interchange the alternator and power steering belts. They are similar enough to still work but will result in the adjusters being at an end rather than in the middle of their range.

The correct belts are:

Power Steering 981680 (formerly 973488)
Alternator 973487

They are the same width but there is a 13mm difference in length. The aircon belt is a different width.

I don't recall any bushes on my power steering pump. Superflex do list one but I'm pretty certain it's for the alternator / aircon bracket

Forrest, we just fitted 3 brand new belts, numbers correspond to yours but the pump is still loose, it doesn't quite100 percent line up with the pulley if you look from the side and you can hear it move when you put the steering on any lock. Clearly something is very wrong.

Edited, misunderstood your post first time reading.

Edited to say that I stood and watched and made sure each number belt was put in the right place! but maybe they were wrong before. Anyway, something is clearly wrong, they will hopefully find out when the take it off.

The attached, lifted from a well-known source, may also help. It looks as though it would be quite easy to reassemble the brackets and bolts incorrectly if they have been apart in the past. Easily enough to put the belt out of alignment.

Cheers. I've emailed my garage that photo and told them there don't appear to be bushes. Hopefully they'll find out what's wrong when they look at it.

It doesn't help that people park opposite my garage and getting on and off my forecourt requires masses of full lock and constant manoeuvres which I know is no good for my rack, not sure if its also bad for the pump?

So, my garage kindly rushed my car in earlier than they could actually fit in in to get me back on the road and they did all the work last Monday and I got it back last Monday night.

The mechanic said that following the Henley mechanics terrible work which had caused my pas pump to be hanging off with the big bolt almost bent at right angles that the Volvo indi in Wales (where I didn't have time to wait for ordered parts, I was visiting my parents briefly at the time of the breakdown) had improvised and done a great and unusual repair job which had lasted since 2016 and some 7000 or miles but it had now failed and as it moved around it had made the holes in metal supporting system get big?

He has now done a lot of work to make it very secure and he said his improvisation at securing it will last a long time but said if I get the two plates and one bracket (or was it one plate and two brackets?) from Volvo it can be put back to how it should be? He said that where is was moving around the holes in the metal had gotten very big as it moved and rotated, does that make sense to anyone?

Can anyone tell me which parts he is taking about and what I need to buy please?

[Laney760]

Can anyone tell me the parts I need to buy please which hold the pas pump in place? The mechanic said two plates and a bracket? All the original Volvo parts had failed and he had to improvise but his work is not meant for long term and I don't want the pas pump to fall off?

Is it 9,11 and 12 that you are after ?
