CRANKSHAFT
1. Bolts and washers (ten each). 2. Main bearing caps (five). 3. Crankshaft.2. Remove the main bearing caps (2) and lower halves of crankshaft main bearings.3. Attach a hoist and sling to the crankshaft (3). Remove the crankshaft, the weight is approx. 102 lbs. (46.3 kg).
REMOVING CRANKSHAFT4. Remove the upper halves of crankshaft main bearings.Install Crankshaft
1. Install the upper halves of main bearings. Lubricate the upper halves with clean engine oil (SAE 30).2. Attach a hoist and sling to the crankshaft. Position crankshaft in cylinder block. If camshaft is in the cylinder block, align timing mark on crankshaft gear with timing mark on camshaft gear.3. Lubricate lower halves of main bearings with clean engine oil (SAE 30). Install main bearing caps so number on cap corresponds with number on saddle of cylinder block. Both numbers must be on same side of cylinder block.4. Put engine oil on the threads of the bolts and the face of the washers and install the bolts into the cylinder block.
Do not rotate the crankshaft until all main bearing cap bolts have been tightened.
5. For 1140 (36B1-36B1923), 1145 (97B1-97B6154), 1150 (96B1-96B6580), 1160 (95B1-95B13691) Engines, tighten the bolts for the main bearing caps in the number sequence shown to a first torque of 60 15 lb. ft. (8.3 2.1 mkg). Tighten all bolts in the number sequence shown (hand torque only) to a last torque of 175 10 lb. ft. (24.2 1.4 mkg).6. For 1140 (36B1924-Up), 1145 (97B6155-Up), 1150 (96B6581-Up), 1160 (95B13692-Up) Engines, tighten the bolts for the main bearing caps in the number sequence shown to a first torque of 30 3 lb. ft. (4.1 0.4 mkg). Put a mark on each bolt and cap and tighten, in the number sequence shown, an added 120° 5° from the mark.
BOLT TIGHTENING SEQUENCE7. Check crankshaft end play. End play with new bearings should be .006 .003 in. (0.15 0.08 mm). Maximum allowable end play is .012 in. (0.30 mm).
