Cab raising ups and downs.

Raising

Before raising the cab, eyeball the cab hinge studs and nuts for cracks. If you find any, let your mechanic know. Don't raise the cab until cracked studs and nuts have been replaced. You don't want to be under that cab if the hinges fail!

Also, remove all equipment stowed on top of the cab before raising it. The elevating jack assembly can't take the extra strain, and falling equipment could kill or injure you or others.

Slow and easy is the way to raise the cab. The faster you go, the more the cab rocks back and forth. That puts a lot of strain on the hinges.

Once the cab is up, check the hinge studs and nuts on the inside, too. Again, your mechanic should replace any damaged ones.

When the cab is raised is also the best time for your mechanic to replace any loose hinge nuts. That's when the torsion bar is under the least strain, so most of the torque will go on the nuts.

Lowering

After lowering the cab, lock it down right or you may ruin the threads on the hold-down nuts or crack the frame.

If the nuts are not seated or tightened right, the cab sits cockeyed. The frame can crack as the cab flexes. The nuts can bind, too, so keep the threads clean. Never cross-thread 'em or the entire hold-down assembly has to be replaced. Use a little oil on the threads occasionally to make the job easier, too.

Release the tension on the elevation mechanism after the hold-down nuts are tightened. That way, there's no pressure on the mechanism while you're in operation. It'll save on busted parts.
