Question for older W900 purists

9 posts in this topic

Posted (edited) · Report post

Working on a 1/16 1980 vintage W900. I seem to recall that more often than not that for power steering, KW used/offered an air assist power steering setup using a cylinder bolted to the frame and the drag link and manual steering box as opposed to the far more common power steering pump, steering box, and resevoir. Am soarly mistaken? Or am I getting this all mixed up with their Center Point steering? Anyone with pix and clarification of either/both setups would be greatly appreciated. Also still needing firewall pix of same.

Thanks.

I believe the cylinder you are speaking about was used on the old manual steering systems. It was just a steering damper for the manual steering system,to keep the wheel from being jerked out of your hand when you hit potholes. It was attached to the tierod tube and the frame rail/spring perch.

It did nothing to assist turning the steering wheel.

Edit,I just checked Google,cant find any images of old trucks with steering dampers on them,but a bunch of images of 4X4's equipped with them.... they serve the same purpose.

Thanks. Familiar with the dampers to reduce kickback. The air assist may have been aftermarket or was hydraulic but i surely do remember them being common if just for a few years. It was marketed as a steering assist package and was not unique to kw. It will come to me or some old tiimer here.

Shepard, ross, and trw were the big steering people for big rigs back then for all makes with trw getting in serios trouble with nhtsa on virtually every true power steering gearbox around this time. Largest recall in semi trucks ever and hurt everone bad.

I started working on trucks in 1982,spent a few years driving trucks after I got laid off from a wrenchng job. Been wrenching steady since 1988. Been working at dealerships/distributors since 1990,(InternationalFreightliner,Cummins,and,currentlly Volvo,and hope to stay here until I retire) ,I do remember an air assist system that was aftermarket,never had to work on it so not sure who made it. However I have worked on several master/slave hydraulic steering systems,those that have a master/slave gearboxes. Now adays I believe Ross and Sheppard are one company and TRW builds most of the Volvo boxes.

Thank you "father" for validating your sons memory banks. It knew it wasn't just a dream after all.

air assist had a valve that was fitted to the steering shaft after the cab.Hoses went from that to a ram.If you look at some Tyrone Malone BOSS TRUCK of America photos you can see the ram

That is so depressing to see, such a grand truck in its time. Look at the remnants of all the pin stripping on the frame.

I want to find that truck and put it in my back yard.
