    After removing the top deck plates I have good access to the top of the engine. I removed the intake manifold, valve cover, exhaust manifold. I pulled the glow plugs and disconnected the fuel lines from the injectors. 20190901_155035[1].jpg 20190901_174515[1].jpg

    And I dropped the oil pan. That was enough as I already worked a full day. I'll have to look through my manual tonight so I can set the engine to TDC before I go any further.

    I wonder if there's a way to lock the engine at TDC like on my John Deere? 20190901_174522[1].jpg 20190901_174718[1].jpg

    Today’s progress;


    Drained the coolant from the block.


    After cleaning years worth of crud off the front of the block I finally found the timing pointer and marks. I engaged the PTO clutch and, using a large pipe wrench on the stub shaft, rotated the crank till I lined up the timing marks. I then verified that No. 1 piston was at TDC on the compression stroke by verifying that the push rods were free to move. I also removed the side cover from the injection pump to check the timing marks there but saw only one. No corresponding mark. I believe timing is 2 degrees BTDC so if I back off No. 1 a bit I may find the other mark. I’ll check that later before I get into pulling the pump.

    Next I loosened all the lock nuts on the rockers and backed off the valve lash adjustment screws to relieve the tension on the rocker arms before I broke all the head bolts free. Then I was able to back off the head bolts in stages following the reverse order of the torque sequence listed in the manual.


    I removed the rocker arm assemblies and the push rods to a cardboard box. I lifted the head from the block.

    Picked up the head today from the machine shop. Besides having several cracks in the injector ports, when pressurized, it leaked like a sieve. 20190906_130410.jpg 20190906_130620.jpg
