Brocky Posted yesterday at 01:58 AM Share Posted yesterday at 01:58 AM I presume a Mack someone will answer your question on a hydraulic power steering application. I read in the John Deere Green Magazine a couple three months ago about an electric power steering unit which attaches to the shaft above the steering box.

T-Mack1 Posted yesterday at 03:06 AM Share Posted yesterday at 03:06 AM Some tv show/or YouTube video I watched a few months ago had a hydraulic pump for the steering that somehow was mounted to the back end of the generator. I always wondered if one of those new electric assist units they make for custom cars could be fitted. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76195-power-steering-for-707-l-model/#findComment-586366 Share on other sites More sharing options...
mowerman Posted 16 hours ago Share Posted 16 hours ago I had one of those on my 55 Chevy bel air…. pump was attached to back of generator with the tie rod ram I’m sure one could use on other vehicles but retro Chevy parts are a fortune good luck.

terry Posted 15 hours ago Share Posted 15 hours ago The power steering pump was standard on B models on back of generator,the the early R models had a belt driven one, then the maxidyne series had it on back of compressor, i have seen on B models where a bracket was made for the belt driven and ran off of front fan belt from crankshaft. terry 2 Quote Link to comment https://www.bigmacktrucks.com/topic/76195-power-steering-for-707-l-model/#findComment-586381 Share on other sites More sharing options...
mattb73lt Posted 11 hours ago Share Posted 11 hours ago I'm not aware of any factory power steering for a lighter L model, like a fire truck, of that era. Heavier construction equipment it was available. It is possible to fit power steering to it with some modification. Add-on units were a later option. Like the hydraulic Garrison units. Those usually had the pump on the back of the generator, a shuttle valve built into the drag link and a hydraulic piston attached to the front axle to the tie rod. Another add-on was from Air-O-Matic. Somewhat the same as the Garrison set up, but tapped into the air system of the truck for the power assist. Those were OK, but when maneuvering in tight quarters you usually ran out of air and had to wait for the air pressure to build back up. I have one that came off my B42 when I first got it. It was prone to leaking when in use, it did help, but would stop the truck when the air ran down and the maxi brakes would come on. Those are still made and available, the most common current application is for the M35 series of military trucks. As for modern electric power steering, I have not seen any other than hot rod applications. Some more searching may come up with a solution. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/76195-power-steering-for-707-l-model/#findComment-586389 Share on other sites More sharing options...
terry Posted 8 hours ago Share Posted 8 hours ago I once owned a B421 dump truck which was a flathead gas job, had a factory sheppard p/s box, with the pump driven off back of generator. terry Quote Link to comment https://www.bigmacktrucks.com/topic/76195-power-steering-for-707-l-model/#findComment-586410 Share on other sites More sharing options...
HarryS Posted 8 hours ago Share Posted 8 hours ago If you are looking to convert to power steering I have a Garrison hydraulic unit that came off of a B model.
