3. Apply clean engine oil to all crankshaft journals and install the crankshaft in place so that the timing marks
on the crankshaft timing gear and the idler gear match. Refer to Gear Train and Timing for the correct method
of timing the gear train.
4. Install the upper halves of the crankshaft thrust washers on each side of the rear main bearing support and
the doweled lower halves on each side of the rear main bearing cap. The grooved side of the thrust washers
must face toward the crankshaft thrust surfaces.
If the crankshaft thrust surfaces were reground, it may be necessary to install
oversize thrust washers on one or both sides of the rear main journal. Refer to Fig.
8 and Table 2.
5. Install the lower bearing shells (no oil grooves) in the bearing caps. If the old bearing shells are to be used
again, install them in the same bearing caps from which they were removed.
6. Install the bearing caps and lower bearing shells as outlined under Install Main Bearing Shells.
If the bearings have been installed properly, the crankshaft will turn freely with all
of the main bearing cap bolts drawn to the specified torque.
7. Check the crankshaft end play by moving the crankshaft toward the gage (Fig. 9) with a pry bar. Keep a
constant pressure on the pry bar and set the dial indicator to zero. Then
