(1) Replace the two belleville washers so that their outer edges, are touching. (Figure A-33.)
c. Flywheel. Make sure the crankshaft taper is free of oil and grease. Insert the flywheel key and slide the
flywheel onto the crankshaft toper. Reinstall the flywheel retaining nut. With the striker bar and a mallet, securely tighten
the retaining nut. (Figure A-34.)
It is extremely, important that the flywheel seats securely on the crankshaft taper. To see if the flywheel is properly
O
seated, first Ioosen the retaining nut. Using a wooden mallet or hammer handle, strike the outer face of the flywheel at 90
intervals (3:00, 6:00, 9:00, 12:00). If the flywheel comes loose, remove it and check once more for oil, grease or dirt.
Clean the taper surfaces thoroughly and reinstall the flywheel. Repeat the test once more. If the flywheel breaks loose
again, the flywheel or crankshaft tapers may be damaged or defective.
d. Oil Pump. Reinstall the oil pump. Note that there are two long screws and one short screw. The two Ionger
screws pass through the bracket on the pump face. Be careful not to distort this bracket when torquing these three screws
to engine specifications. (Figure A-35.)
e. Connecting Rod. Note the painted marks on one side of the connecting rod. When installed, this side
should face the injection pump. Also be sure that the stamped match marks on the connecting rod and cap are aligned on
the same side of the rod. (Figure A-36.)
