Liner projection should be 0.002 to 0.005 in. with a maximum difference between liner projection of 0.002 in.

There are no special run in requirements but the 4T manual does state that you should operate at light loads for the first 64 hours on a new tractor.

Avoid long periods of idling.

Good luck with your start up.
