V8 specialist needed.

[Steve 90]

I have a 4.2 V8 from a K reg LSE. The PAS pump and pulley are missing. I don't need the pump, only the pulley so I thought no problem I'll order it by chassis number.

Not so easy. The one they say it should have has 2x single V groves but im sure the PAS pump on the RR it came out of had a Multi V belt from the crank to the pump which then had a single V drive up to the alternator. This could be wrong but I seem to remember it being like this.

On the front of the crank there is a single V pulley which drives the water pump, Which is then piggy backed off to the Air con via another single v belt. Behind that on the crack is a multi v pulley (6 rib I think) which shows sign of being used and is the one I thought drove the PAS pump and in turn had a single V piggy back up to the alt. At the back on the crank (closest to the block) there's sign of another single V which also looks to have been used but I cant work out what for.

Have I got this right???? Am I imagining the PAS pump having a multi V and single V pulley(which landrover say does not exist)???? Is it supposed to be set up some other way that I have missed?????

Hope someone can help as Im trying to sort the bits and make brackets for the ZF steering pump and would like to know how it is originally, Although it will probably be very different it would be nice to know!

Thanks in advance.

Steve.

My 4.2 was the same, although I never used the multi V.

A setup I have seen: belt around crank, water pump and PAS - double pulley on PAS and water pump - belt from PAS to alt and belt from water pump to air-con compressor. All three belts single V.

These are from the LSE engine bay

Cheers Mate. It all makes sense now.
