Steve 90 Posted June 26, 2007 Share Posted June 26, 2007 Got the zf74 pump today. Not realy sure how its gona fit to the 200 TDi (disco engine). Because the discovery engine has a double pulley on the P.A.S pump which a belt is then piggy backed off to run the alternator, If I try and mount it in the original pump possition then im gona have to machine a long adaptor to get the double pulley in the right place. This in its self is not a problem but the issue I have with it is overloading the bearings in the pump with the extra leverage gained by extra offset on the pulley. The other option I was thinking about was to remove the pressure valve from the original pump and leave it in place with a length of pipe connecting the input and output just to circulate enough oil to keep it lubed. that way it just acts as an idler. Then I can mount the P.A.S pump next to the second alternator which is on the Air con comp' mounting. Only problem with this I see is the pump will then be at the same height as the resevoir and might not have enough oil supply. Plus I really dont like over complicating the truck as it just tends to be more to go wrong! Has anybody here mounted a ZF74 on a Disco 200Tdi or have any other ideas??? Cheers. Steve.

Steve 90 Posted June 26, 2007 Author Share Posted June 26, 2007 One more thought, Does anybody know if these pump's scavenge at all? Might not be such an issue to mount it level with the resevoir if they do! Quote Link to comment Share on other sites More sharing options...
Mark Posted June 26, 2007 Share Posted June 26, 2007 Have you got Aircon? if not then you should have a spare groove on the crank pulley. You could then use the aircon mmounting point (4 tapped posts) to make some kind of bracket and tensioning affair? This does mean the pump will be pretty high up though, and my give you issues with the reservoir? just a thought Mark Quote Link to comment Share on other sites More sharing options...
Guest diesel_jim Posted June 26, 2007 Share Posted June 26, 2007 Then I can mount the P.A.S pump next to the second alternator which is on the Air con comp' mounting. Cheers. Steve. I've seen pictures of a york 210 compressor mounted next to an alternator on an engine, so you could mount them together. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted June 26, 2007 Share Posted June 26, 2007 I may have a spare (non-LR) ZF mount somewhere if it would be of use, I will dig it out and take a piccy. Quote Link to comment Share on other sites More sharing options...
