I recently replaced the power steering pump on my 1975 Shadow LRD20648. In the U.S., NAPA has the core available for about $50, part number 81-691. Don't forget to also replace your high-pressure and return line hoses if needed. | ||

Matches with Rolls part number UE39652SXR, CHASSIS RANGE 4549 - 41601 Saginaw pump. The NSP81691 has a Nut-Retained Pulley as pictured in the parts manual. Also fits most GM V-8 cars from '69-'74, if you want to get it from a different store, as seen here: http://dmauto.com/web/dmauto/Catalog/NAPA_ECAT/fits/NSP/81691 My site shows NSP20840 which has been superseded by NSP811391 which will work, but has a Pressed on Pulley. I'll change my site info to reflect the more correct pump. $46US compared to Rolls about $370US is a big savings for the few that care about prices. Thanks for pointing this out.

....and in Australia, you will find this standard Saginaw pump at every wreckers for $10 or at a steering shop for $50 new. It first dawned Downunder on EH Holden Premiers (it was a rare optional power steering feature in '64). Imported Chevs and the like all had them from 1959 through 1988, and they were ubiquitous 1:1 on Oz cars for decades. This is all first-hand information. | ||

For the more energetic/adventuresome owners try overhauling the whole system. For cars which have been grinding along for nearly fifty years with a system that was not designed to last that long, it is well to remember that the resulting crud that any machine generates is lodging in the bottom of the of the steering box. This is where the cylinder and piston that gives the push to your steering is located. The sludge works as a grinding paste and boxes are now starting to fail. The best prophylaxis is to remove the steering box and pump, flush all the lines send the large bits off to a specialist and for a nominal fee they will be brought back to scratch and you can drive around for the next say 20 years with peace of mind. Otherwise, consider putting a transmission filter in the return line These also have a magnet in them to pick up nasties. If the fluid has never been changed a couple of changes of filter may be required to clean the system up. Even more otherwise, if all this is just too much buy yourself a suitable small strong magnet, tie a bit of wire on it and drop it in the reservoir. Pull it out from time to time and clean it. The Shadow and Spirit do not enjoy filters in their systems like the old Clouds!! | ||

Its good that this is old news to those who've known it for a long time. But, it is also good that now there's an actual part number, and chassis number range that those who don't know can easily find reference to. Other things people know, but are difficult to nail down are: Anyone know which pump will work in the '81-87 regular cars, and what the difference is in the Turbo cars? UE42700 & UE43700? Also, is there a comparable pump for the 20,000 series cars UR72303? Clearly the number 7846075 is engraved in the pump, and this comes up as late '80s Jaguar XJ-6, XJ-40, and some Chevys. But, those pumps have the return hose on the opposite side of the casting as seen in the pics: Rolls Pump:  Jaguar Pump:  Larry http://mutley.hypermart.net/RollsSubstituteParts.html | ||

The only one like the 20,000 series pump UR72303 I found so far where the return hose nipple goes the correct way is Atsco 6150/Cardone 20870/AC Delco 36-516150 fitting various GM cars like the '83 Malibu 4.3L Diesel, or '87 Jeep Cherokee 2.1L Diesel. Anyone's experience corroborate this?

Larry - Anyone know which pump will work in the '81-87 regular cars, and what the difference is in the Turbo cars? UE42700 & UE43700? I think it's just the mounting brackets. Also remember that some of the brackets are fitted behind the pulley so that will need pulling off and pressing into the new pump. I think some pumps have threaded spindles which are obviously easier. Magnets etc. I also love that Saginaw pumps have a magnet placed deep inside the pump body for easy access! | ||
| Bill Coburn Moderator Username: bill_coburn Post Number: 1147 Registered: 4-2003 |
Paul/ I think that remark is the best oxymoron I've seen on this forum - a magnet deep inside of the pump body for 'easy access'.. Now I think of it perhaps my sense of humour is slipping. Not being prepared to believe you I called my power steering man and he confirmed that the magnet is accessable under the cover of the pump. I could not even find a reference to it in the manual! I suppose this is in the same design philosphy as the seat memory boards being eaten by battery guts something else not mentioned - still it does help to turn stock over!! Are you aware of the steering box replacement castings on Shadow I's. They were no longer available years ago and as far as I know nobody had devised a means of recovery of the old ones? | ||
| Paul Yorke Grand Master Username: paul_yorke Post Number: 361 Registered: 6-2006 |
Bill, I'm not sure what has upset me the most, you forgetting my sense of humour, or you thinking I may be lying! I thought you were pedantic about your servicing of these cars, frankly I'm quite shocked you don't clean the magnet every 24000 miles or every two years (whichever comes soonest) | ||
| Paul Yorke Grand Master Username: paul_yorke Post Number: 362 Registered: 6-2006 |
But to be honest, I'd have been even more shocked if you had! LOL. Never running the pump without oil and changing the oil often certainly is the best method of prolonging the life of the steering components - which, I know,is something you are a stickler for. | ||

Well thank you I am relieved! This last burden of a '72 Shadow which had eratic steering which was traced to the box. One would get lumpy steering and extraordinary squarks. I sent the box and pump to my bloke in Sydney who specialises in overhaul and he said the muck in the bottom of the box was like porridge! This was in a car of 90,000 miles and garaged and not abused etc! Felicitations etc as usual! | ||

Greetings from Ottawa Canada I saw the reference by Bill Coburn about a Shadow with erratic steering which is exactly what I have on my 1975 Shadow 1 since acquiring. Had my local guy go over it without success. He reports all links and joints OK. Symptons are that it wanders on the highway but more alarmingly, "jumps" when on a long right turn curve as in entering a freeway. The jump causes the car to change direction noticeably and this can be felt through the steering wheel. It's quite alarming Have found another mechanic who has a good reputation but he wants to replace most of the steering system at considerable cost. Car is in excellent condition and obviously been well looked after. It only has 85,000 miles Any advice much appreciated. Colin Billowes VIN SRD21697 (Message approved by david_gore) | ||

First have the sub-frame resilient mounts checked by a R-R/B specialist who knows how to check them. You should have both the front and rear subframe mounts checked as problems at either end could cause this erratic behaviour. Replacing the mounts is possible for a competent DIY custodian with workshop facilities and who has taken the time to research this and other forums for information on the mounts. Otherwise, leave it to someone with experience. | ||

There's an article at the beginning of the latest issue of T-One Topics, number 93, that could explain this kind of problem. If an anti-roll/torsion bar mounting came loose or the rubber was perished it would tend to allow the wheel on that side to move in an uncontrolled manner resulting in greater bump-steer. I would imagine that it would be worse on long bends as the steering would be held out of straight ahead for a longer period so the effect would be more noticeable. Just a thought. | ||

Does someone have a replacement part number for a power steering pump on an 86 Silver Spur? A couple miles from home my power steering stopped working. Got home and the engine compartment was glossy from the power steering fluid. If I'm replacing the hose(s) and the pump was run dry due to the leak, replacing the pump is in order. | ||

UE46143. No impediments, apart from a few small $, are in the way. |
