How can you make an old semi with power steering turn faster?

Are you kidding?

Go slower.

And grease that fifth wheel. A little goes a long way for her.

 

Oh.

Ok. Let's go over the obvious I suppose. Did you check the power steering in fluid maybe? Maybe check to see if you are losing line pressure needed to actuate the front end? Maybe grease the front end? If you still had the old style grease pins that pour out a dab when full off the grease gun.

Are you using a spinner knob maybe? How is that steering column?

Are you trying to use a wide front construction type steers? Or maybe walking beams back there under your drive tandems? She will need a little more room to do that sidestep than ordinary non walkers.

Single drive axle will always out turn in time and space a tandem dual anytime.

Maybe you don't have a set back axle? Will that help? (In the front some trucks have the setback)

How are your leaf spring suspension brackets doing? While you are in gym up there in that cab working hard, maybe your leaf springs are wanting out from under there?

Is your engine pushing enough to the power steering pump? Hows the belt if you use one to drive it.

Little things. But a barrell of monkeys to my mind. I can think of a couple other things but I think this is a nice little list.

 

It will only turn as fast as the gear ratio in your steering box will allow.

You want it to turn faster a new box with a faster gear ratio is what you need

 

Put on a smaller steering wheel?

 

Put engine oil in your steering gear box. It may help increase pressure. There is something else I've read about steering locks adjustment.

 

You want it to steer faster or sharper?

 

Wow.

This is the RIGHT answer, it has nothing to do with the pressure from the pump or anything hydraulic, it has to do with the gear ratio and the ratio of the steering linkage.
