I've had a few issues with the power steering on my car over the years; the mounting lug on the original pump snapped off half way round the Nurburgring, a "good used" pump from a well known breaker lasted about 20 mins before declaring itself fully incontinent, I rebuilt another used one with a seal set and managed to pull the mounting bolt out on track - remounted it with one big bolt but that one but it then started to weep fluid too 6 months later.
"If only I could buy a new pump" . . . Well - there is one listed on PET for about £600, thanks but no thanks.
Until some t'internet research brought up the fact that the E30 power steering pump uses the same seal set as the 944 one and closer inspection revealed that only the pulley position on the main shaft was different. So I purchased a new pump from here on eBay: https://www.ebay.co.uk/itm/221908115702 (I offered £90 and he accepted £100 fact fans). Undid the four bolts holding the two halves together, swapped the main shaft over with the pulley attached and put a new circlip on, pump halves back together, mounting bracket in place - looking good!
i swapped the pump ovper, replaced the crush washers with dowty seals, fitted a new reservoir tank (£24 from Porsche or £14 delivered for an identical one for a 5 series/X5/etc. https://www.ebay.co.uk/it...64343309 ), also cut the rubber line off the cooling loop and used the Arnnworx replacement hose. I'd planned to replace the reservoir-to-pump hose with some push lock hose and AN fittings that I had spare but the straight fitting wouldn't physically fit in the space so I reused the old hose (I've ordered a 90 degree fitting and will swap the hoses over at some point).
And I can now report that it doesn't work.
Only joking, it works faultlessly - I've driven innumerate 944s over the years and the power steering on mine is easily the best now (as it should be I suppose) - no groaning at full lock, just linear and direct, all for under £150.
Worth pointing out that I ditched the original mounting method some time ago too. I removed the pulley on the bench and ran a single bolt through from the front, through the correct spacer and with a nut in the middle as a spacer like the original bolt, out the back, through the spacer and then a nice big washer and a nyloc nut. Pulley back on in situ and job done, no more damaged lugs, pulled through bolts, etc. on track.
