Hoping someone in Aus can help me out with a Hobourn Eaton pump for my MK111 p5? Mine has spun the drive pulley off and chewed up the keyway. TIA Tim.

I don't but I know someone who probably does. I will ask him tomorrow. Post a picture of yours so that I know what I am looking at. COI: mine is a MkIIb and is driven off the generator.

My MkIII has the PS pump on the back of the generator too. Perhaps the pump is a modification that a previous owner has done?

Good morning - the power steering pump was ALWAYS fitted at the rear of the dynamo (which is different from an alternator).
The pump is driven by the dynamo so that a disc piece about 5 - 10 mm thick is placed between the dynamo and the pump, to transfer power from the dynamo to the pump.
This disc is shaped with grooves in it so that one end fits the shape of a connecting piece sitting in a groove in the anchor (spindle) of the generator, and a similar conneting piece fitting in the groove on the the axle driving the pump.
Note the pump is different between the P5 and the P5B, in that it has different fitting lugs. Still, the concept of transferring power from dynamo to PAS pump is the same on both versions.

The V8 has a completely separate ps pump. Its on the opposite side of the engine bay to the alternator.

Sorry for the confusion. Mine is fitted with a v8 from an sd1. I just assumed they would be the same. Mine has a stand alone pump down low on the passenger side. I do have a spare motor out of an early range rover. Theyook similar pumps apart from the pulley. Anyone confirm if interchangeable? TiA Tim.

The pumps are basically the same apart from the the pulley shaft. The rear mounted dynamo driven version has a tang to locate in the special sleeve on the dynamo armature. The pulley version has a keyed taper/nut
