Maddog13407 Posted October 2, 2013 Share Posted October 2, 2013 everyone I have seen had a Vickers pump driven off the back of the air compressor. have seen them coupler driven and belt driven off the back of compressor.

39 Baby Mack Posted October 3, 2013 Share Posted October 3, 2013 That was going to be my suggestion Matt.To change the air compressor and run a Vickers pump.He is right though the early power steering pumps were Eaton and drove off the back of the generator.They used a special end frame for the generator so the pump would mount to it and a small rubber coupling to drive the pump.We had 2 '58 "B" models with that set up on them for Ross assist power steering.As an added bonus he could rid of the generator and change it over to an alternator!Ron Quote Link to comment https://www.bigmacktrucks.com/topic/32997-55-b61-shepard-power-steering/#findComment-209736 Share on other sites More sharing options...
Maddog13407 Posted October 3, 2013 Share Posted October 3, 2013 yup, agreed! I had all those plans for my B when I put it together but finally just put it together and drove it, then added maxi brakes after, this winter I think im gonna ditch the generator and regulator for an alternator. I can take some pictures of the pump if you want or get you the Vickers # over the weekend. I have a few on trucks. my B had one that was belt driven off the back of the compressor but I think most R models had gear driven ones coupled direct? I have seen the generator driven ones, even seen a few setups go to the scrapyard before.
