Talking about seals - PAS pump seal


Recommended Posts

My PAS pump on my 1989 diesel turbo 90 leaks a lot, but when regularly topped up, gives reasonable steering assistance. Given that a new pump will cost at least £110 plus VAT, I am tempted to try and change the seals on the pump - available here for £2.95.

Has anyone done this and have they any tips? Apologies if there has been a post on this already but I couldn't find it.

Do a search Mark. There was someone here had stripped and o/hauled their pump and posted up with lots of pics. Maybe in Tech archive. I didn't think it was doable before but for £110 its got to be worth a try.

SimonB might be able to help in a few weeks, I am about to give him my old pump to recon (or try).

He already does alternators so it is v similar process.

Handy tip - if you can get a pump that is correct on the front then the CAN will come off the back and be swapped for yours so that the inlet pipe is in the right spot for your motor. (if that makes sense)

We replaced ours for the 110 (Cost £99 once we'd sent the old one back) I'd been told replacing the seals was a bit of a false economy, and so went for a new pump. Really makes a difference as well. Ours wasn't p*ssing it out, but would give 3 or 4 big blobs once it got warm.

i rebuilt the 'non-serivcable' pump on my 200tdi disco. i dont know if your pump is similar but that was easy enough by working through it & making notes of how it went together.

on my pump the shaft comes out the front of the casing & is retained by a hidden springclip, so check twice, hammer once. replace the bearing while your in there, i think it was £6 from a bearing specialist for mine.

I've got a duff [front bearing wrecked] pump off my 200Tdi, I'll have alook at it witj your info, it might just be fixable.

western, the 'plate' the pulley bolts to slides off the shaft. behind that there is a plastic dust cover, the clip is behind the dust cover.

once the pressure relief valve is out the can will slide off the back with a bit of effort. it seals with an O-ring, i didnt bother to replace & it didnt leak. there is also an O-ring on the pressure relief valve & an oil seal behind the bearing.

i have a feeling defenders have gearpumps unlike discos with have rotor & vane pumps. however i did a disco pump & got a mate who once did a defender pump. both seem to come apart the same. heres a few pics of mine in bits, hopefully they'll be useful. in the last pic you can see the new bearing i fitted, the ridge the clip fits behind & the damage i did to the casing discovering the clip.
