Re: Help needed on p/s conversion for 56 k/w
I don't know if old KW busses use the same simple straight-axle front end as KW trucks but I'd suspect they do.
A few years ago I simply swapped the front axle, pump, etc. from a late-'80s Kenworth into an old, never-had-power-steering 1974 KW W-900 with a Cummins. It was pretty straight forward, just remove old stuff and bolt on newer stuff.
The extra benefit is the later front end had brakes.
The old trucks with air-assist steering I've driven really sucked. They didn't have much "assist" and when making tight maneuvers they used up all the air quickly.
If I was going to convert to power steering (again!) I'd still not bother with retrofitting old obsolete junk.
Look, measure, research, and if possible just bolt in more modern stuff.
P. S. You can probably just replace the old non-power steering box and not the entire axle, I wanted the brakes and higher capacity axle as well so I just swapped the whole thing.
Like I said, it was a truck not a bus but it's probably a similar situation.
Then I lived happily ever after.
