      Yes, it's doable, but consider:

      1) Any ROPS certification will be lost unless you are a certified welder.

      2) Are you short in stature? wink

      3) The sweeps will also have to be shortened.

        You can take lead readings to determine the actual clearance between valves and piston, and head and piston, then you can determine how much material you can safely remove. It your post you are using the numbers one-and one-half thousandths of an inch and two-and-one-half-thousandths of an inch. That's not very much at all. If the machine shop used an accurate straight-edge, they could determine easily enough how much material to remove safely with a feeler gauge. I would try a different machine shop, their lack of knowledge kinda scares me. Usually a 0.005″ to 0.015″ cut is sufficient to eliminate any warpage without issues. 

        Also, when tightening the head, do it in two stages following the sequence each time. First, torque to 75% of the full value. Second, torque to 100% of full value. Make sure all threads are clean.

          Northern Tool does have the manual in stock. The part number is XCOMAN06.

          It would be nice to have.

          Do you know how much an operator's, service, or parts manual cost for a Cat D3? This is a bargain at 3x the price.

            That is not a common problem that I am aware of. If the right steering clutch won't disengage, then the machine will not turn to the right. Same if the brake/steering clutch operating sequence is out of adjustment. The symptoms you describe have been noted in machines that have been idle and stored outside for extended periods.

            It would help to know whether it has pendulum pedals or direct link pedals.

            Northern Tool is your first contact for owner's and parts manuals. All common and simple adjustments are covered in the owner's manual. There is no service/repair manual available.

                Pepage, do you have steel or rubber tracks. I forgot.

                I will count teeth on my rubber tracked sprocket and idler on the 5th.

                    Nice read on tracks. (The line break is intentional so the full link will

                    show. Hopefully).

                      I wish I could read your post accurately

                      but the admin Hal is asleep at the switch

                      again, so only write a half page.

                       

                      That's weird, I have never heard of two

                      different track pitches for these dozers.

                      Bummer. Maybe you can get some relief

                      from Eastwind or Yuchai over it.

                        Are you barring the engine over by hand using a pry on the ring gear teeth? I have witnessed a case where the ring gear was cracked and just spun on the flywheel. It wasn't on a Chinese tractor, but it led to some head scratching. Watch the flywheel as you pry on the ring gear teeth.
