Crankshaft Main Bearing Cap/Bedplate

- Before installing the bolts the threads should be oiled with clean engine oil, wipe off any excess oil.

- Install main bearing cap/bed plate to engine block bolts 11, 17, and 20 finger tight. Tighten these bolts down together until the bed plate contacts the cylinder block.

- To ensure correct thrust bearing alignment, perform the following steps:
Step 1: Rotate crankshaft until number 4 piston is at TDC.
Step 2: Move crankshaft rearward to limits of travel.
Step 3: Then, move crankshaft forward to limits of travel.
Step 4: Wedge an appropriate tool between the rear of the cylinder block (NOT BED PLATE) and the rear crankshaft counterweight. This will hold the crankshaft in it's furthest forward position.
Step 5: Install and tighten bolts (1 - 10) in sequence shown to 41 Nm (30 ft. lbs.).
Step 6: Remove wedge tool used to hold crankshaft.

- Tighten bolts (1 - 10) again to 41 Nm (30 ft. lbs.) in sequence shown.

- Install main bearing bed plate to engine block bolts (11 - 20), and torque each bolt to 28 Nm (250 in. lbs.) in sequence shown.

- Tighten bolts (1 - 10) to 75 Nm (55 ft. lbs.) in sequence shown.

- Tighten bolts (11 - 20) again to 28 Nm (250 in. lbs.) in sequence shown.

- After the main bearing bed plate is installed, check the crankshaft turning torque. The turning torque should not exceed 5.6 Nm (50 in. lbs.).
