David Posted June 6, 2011 Share Posted June 6, 2011 I have some R600 shafts that you could lengthen. Your truck looks like a Superliner I, I thought a '86 would be a Superliner II.

rhasler Posted June 6, 2011 Share Posted June 6, 2011 I think that part number is for the housing in the cab that the steering wheel sits on top of. Quote "Mebbe I'm too ugly and stupid to give up!"

Rob Posted June 7, 2011 Share Posted June 7, 2011 The "+" section is for the telescopic feature of the column. If you don't use this feature it is not needed. The second thing this does is allow steering column collapse in the event of a front end collision. This was mandated for the 1968 model year in USA for light trucks and automobiles. You could get any splined shaft and socket, then "time" the universals in sync with each other. As David said you could also lengthen an R600 shaft easily also. Ensure you keep the timing of the universals correct meaning either in the same angle plane, or 90 degrees from each other, otherwise the shaft will bind against itself when turning.As mentioned, a driveline shop can set you right up.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Lmackattack Posted June 8, 2011 Share Posted June 8, 2011 When i put power steering on my truck I had to cut down the shaft and then re weld it. If you can find any used shaft that is in good shape I think you would be able to have it milled down and re welded . the guy that made mine drilled a hole in the shafts where the new weld was and then was able to get better penatration for added safty. It will likely be cheeper than getting a new part.just my .02Trent Quote Link to comment https://www.bigmacktrucks.com/topic/19325-need-a-steering-shaft-for-my-superliner/#findComment-79303 Share on other sites More sharing options...

When the steering gear is mounted to the steer axle the splines work much the same as a driveshaft with the slip, and spline moving with the axle. This induces a lot of wear into the shaft splines. Much like a driveshaft the shaft has to endure the torque of twisting also. These needed greased often but a lot were neglected. A steering gear that is frame mounted does not have the same rigors on the input shaft this setup does.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

In most wrecks the front tires end up at the fuel tanks. Seems like that would sent that shaft through the driver's belt buckle.

Seems like that would sent that shaft through the driver's belt buckle.They did that to give about 1/2 second warning before impaling the driver's chest. In reality, this is the reason for the collapsable steering column. In cars, the steering column has to collapse 3" before moving the entire column by federal mandate.Mounting the steering gear in that fashion was a bad design in my opinion.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

fifth wheel Posted June 8, 2011 Share Posted June 8, 2011 The first generation Superliners are on Cruiseliner chassis have axle mounted steering gear and the hood attaches to the radiator sides. Not an ideal place for the steering box but it works.FW Quote Link to comment https://www.bigmacktrucks.com/topic/19325-need-a-steering-shaft-for-my-superliner/#findComment-79336 Share on other sites More sharing options...
