T2000 turning radius

we tried to do it with trw box and with 315/70R22.5 tires they touch frame, so it is possible with 295/70R22.5 ore with 275/80R22.5 tires

 

Most steering boxes have auto set poppet valves that are set initially when the truck is built. What sets the poppete is the steering stops in the spindles making contact with the axle beam. If the poppets are properly set there should be about 1/4" gap between the stop and axle when the gear runs out of power assist. Turn the wheels all the way and check the clearance between the stops and axle. Sometimes they just aren't set properly and the gap is too big, meaning you do have more wheel cut room available. To set them all you do is jack up the axle and turn all the way until the stops make contact with the axle. If they are already making contact those stops are adjustable. You can screw them in to make a tighter wheel cut. You have to watch for how much clearance your tires have with inner fender, drag links, shocks or whatever. If you make any adjustments make small ones because those auto poppets are hard to reset if you go too far.

 

often times the bolts that act as steering stops may not be set right. I have driven 2 different trucks of the same model, specs and wheelbase that turned differently. Turning in the steering stops by only a couple of threads can make a world of difference, but make sure everything has clearance.

 

Don't know about the T2000, but Kenworth had a bulletin on adjusting the stops on the T800s, and W900s. People were screwing them in so far that it was causing the frame rails to crack near the spring hangers. I have turned them in on every Kenworth I've owned, sometimes it helped, sometimes the "stop" was somewhere else. Was lucky enough not to crack any rails, but know of two W9 owners that were not so lucky.
