Removal and Installation

REMOVAL
1. Remove oil pan and identify bearing caps before removal.
2. Remove bearing caps one at a time. Remove upper half of bearing by inserting Special Main Bearing Tool C-3059 into the oil hole of crankshaft.
3. Slowly rotate crankshaft clockwise, forcing out upper half of bearing shell.


NOTE: Only one main bearing should be selectively fitted while all other main bearing caps are properly tightened.

INSTALLATION
When installing a new upper bearing shell, slightly chamfer the sharp edges from the plain side.
1. Start bearing in place, and insert Main Bearing Tool C-3059, or equivalent into oil hole of crankshaft.
2. Slowly rotate crankshaft counterclockwise sliding the bearing into position. Remove Special Main Bearing Tool C-3059, or equivalent.
3. Install each main cap and tighten bolts finger tight.
4. Tighten number 1, 3 and 4 main cap bolts to 41 Nm plus a 1/4 Turn (30 ft. lbs.) plus a 1/4 Turn.
5. Rotate the crankshaft until number 6 piston is at Top Dead Center (TDC).
6. To ensure correct thrust bearing alignment the following procedure must be done:
a. Move crankshaft all the way to the rear of its travel.
b. Then, move crankshaft all the way to the front of its travel.
c. Wedge a appropriate tool between. the rear of the cylinder block and rear crankshaft counterweight. This will hold the crankshaft in it's most forward position.
d. Tighten the #2 Thrust Bearing cap bolts to 41 Nm plus a 1/4 Turn (30 ft. lbs.) plus a 1/4 Turn. Remove the holding tool.

NOTE: Whenever an engine has been rebuilt, add one pint of Mopar (R) Engine Oil-Supplement or equivalent to engine oil to aid in break in. The oil mixture should be left in engine for a minimum of 805 km (500 miles) and drained at the next normal oil change.
