Popular Post 66dc75 Posted February 22, 2018 Popular Post Share Posted February 22, 2018 Finally got the rebuilt air assist steering back on my Autocar. Had to weld the mounting bracket back together due to a dumbass (me) cutting it when I removed the air piston thinking I wouldn't be spending the money to put it back on. I was wrong. Jacked up the front end and greased the hell out of everything. Hooked up the air line and now I can spin the wheel lock to lock with the palm of my hand. Couldn't turn the wheel at all without the truck rolling before. Been chasing down air leaks on this thing for a while and now was down to one leak left in the least accessible spot known to man. 5 port bulkhead fitting top of firewall behind the clutch pedal bracket and every airhose in the truck. so to replace 1 hose, remove dash panel headlight switch panel, wiper switch throttle bracket and undo 6 lines and disconnect the low pressure switch wire just to almost get my hand in there. Sure ain't gonna put any of the old lines back in so now its 6 lines 12 fittings. Hoping to run out of old hoses soon but at least I can turn the steering wheel now without the maxis coming on. 6 Quote Link to comment https://www.bigmacktrucks.com/topic/52589-where-does-it-end/ Share on other sites More sharing options...

66dc75 Posted February 22, 2018 Author Share Posted February 22, 2018 Some blood, some pain, a possible trip to the chiropractor and the air manifold thing is out. That thing is definitely getting relocated someplace else. the low air switch was on top of this up against the bottom of the dash, that would explain the newer one mounted at the wheel sander control. I didn't know the Autocar factory was staffed by sadists. Now that I've got everything apart, I'm seeing wiring that I don't like the looks of. Might as well......... 2 Quote Link to comment https://www.bigmacktrucks.com/topic/52589-where-does-it-end/#findComment-392676 Share on other sites More sharing options...

Freightrain Posted February 23, 2018 Share Posted February 23, 2018 And here I thought the B model was a horrible dash design? I kick and scream every time I have to even THINK about pulling the dash panel to get to something. You can't do it. It's bad enough the steering column is in the way, but you have to squeeze your hand in there first to get tach cable loose so you can pull the panel out enough to even get to anything. Make sure the batteries are unhooked, as the key switch is HOT and if you lean it down it will touch the dash and POW!!! Glad to see you got the air steering working. I had to rebuild my mounting points as they were all egged out. Lucky I work at a machine shop!! Did you put a flip valve to turn the steering off? Did you add another air tank? I did both. Don't usually need to ever turn it off, but the extra tank helps a bunch. Quote Larry 1959 B61 Liv'n Large......................

66dc75 Posted February 23, 2018 Author Share Posted February 23, 2018 Yup I put on an extra tank and it already had a shut off valve which I didn't know was there until I met the original owner at a truck show and he filled me in on a lot of stuff.

66dc75 Posted March 1, 2018 Author Share Posted March 1, 2018 So after a lot of twisting, cut up hands and general cursing I got all the airlines in the dash, dash lights repaired, some wires replaced and a new marker light switch, got everything back together. I have one more air leak out of the bell shaped valve(?) nippled to the spin on filter (i think water seperator also). I know when I don't know something, does anyone know what that thing is for?

carlotpilot Posted March 1, 2018 Share Posted March 1, 2018 no it should not i`m not sure that its rebuildable but i think it is` its a limiting valve for the trans since a fuller does`nt need 120 psi air to shift Quote Link to comment https://www.bigmacktrucks.com/topic/52589-where-does-it-end/#findComment-393217 Share on other sites More sharing options...

carlotpilot Posted March 2, 2018 Share Posted March 2, 2018 could be if its leaking that much I believe 65-75 psi is where they`re set so it has to hold at least that much Quote Link to comment https://www.bigmacktrucks.com/topic/52589-where-does-it-end/#findComment-393219 Share on other sites More sharing options...
