Syncro LHD T25 Power steering /pump/rack
Posted: 17 May 2010, 07:45
Im after a power steering pump as I think mine is not outputting enough and the steering is getting heavy. There are no leaks from the system.
Any suggestions
I have put new seals and filter in the old pump which improved it for a bit but its back where it started and too heavy to drive long distances. There are signs it overheated as the oil smelt so I wondered if the releaf valve had lost its temper and was opening early. Unfortunately the spring is held in by a fixed metal diaphram different to the exploded Diag in the Bentley Manual so I couldnt get it out.
The vanes inside still looked good though with microscopic scoring on the faces which you would expect from 250,000 km I guess.
Alternatively anyone know a place that can pressure test the pump output , I am based in Chester.
I used to have a volvo 250 and you could up the torque on the rack to compensate for loss of pump pressure in older vehicles which worked a treat. Can this be done on VW racks and if so how?
