Hello Fellow Bus Nuts
I have an F8000 cabover fire truck, year's about a 1975. It has a CAT 3208, and weighs about 22,000 lbs.
It has always been hard to steer, it reacts so slowly and sluggishly to the movement of the steering wheel that you cannot, for example, move the wheels effectively to park, and if you had to really make a sharp turn all of the sudden, especially at low speed, it simply would not do it and leave you high and dry.
I've seen this also one time on a Crown bus. Actually it's scary, as you're turning as hard as you can, but the vehicle is resisting, which I thought almost impossible with modern power steering.
Anyone ever have this experience? I drove a Manual Steering Deuce and a half grossing 20,000 lbs at times, and that steered a lot easier than these two vehicles!
Thanks to all the mechanics that know what I don't

If it's not the right fluid, it'll be tough to steer......
But, you might want to ask at the "Ford Truck" forum, too.. |

I have had this happen on other vehicles.
The seals in the steering unit were bad and basically the steering is fighting any change of position with pressure in both directions.
But hard to say without driving or seeing it.

I talked with my veteran mechanic and resident respected elder Bill, He said it was probably because on the old hoses that the fire truck uses, the interior deterioraties, and that causes the introduction of gunk from the hoses clogging the tubes, until you eventually can't get proper hydraulic power.
He said to check out the lines (Im sure there is some systematic procedure to follow to trace this down) and then replace the damaged hose(s)
I'll write back if it works.
