1. Use tool (A), and turn the engine flywheel to move the connecting rod cap bolts into a position for removal.
2. Remove bolts (1) to remove bearing caps (2) from the crankshaft and connecting rod. Remove the lower half of the bearing from caps (2).
3. Push the connecting rods away from the crankshaft, and remove the upper halves of the bearings from the rods.
NOTE: Install rod bearings dry when the clearance checks are made. Put clean engine oil on the rod bearings for final assembly.
4. Clean the surfaces where the bearing halves fit. Install bearing halves (3) in the rods and caps (2).
NOTE: For complete details concerning measuring bearing clearances, see Engine Bearings And Crankshafts. Form No. SEBD0531.
5. Check the bearing clearance with Plastigage. Put caps (2) in position on the connecting rods, and make sure the number on the side of the cap is next to and respective with the number on the side of the connecting rod. Tighten the bolts in the number sequence shown as follows:
| NOTICE |
|---|
When Plastigage is used to check bearing clearances, do not use an impact wrench for the torque tightening sequence. |
NOTE: Bolts (4) and (5) are installed on the same side of the rod cap that has the locating pin. The locating pin must extend 4.0 ± 0.5 mm (.16 ± .02 in.) from the rod cap.
a. Hand tighten bolts No. 4 and No. 5 to a torque of 90 ± 5 N·m (66 ± 4 lb.ft.).
b. Hand tighten bolts No. 6 and No. 7 to a torque of 90 ± 5 N·m (66 ± 4 lb.ft.).
c. Hand tighten bolts No. 4 and No. 5 to a torque of 90 ± 5 N·m (66 ± 4 lb.ft.).
d. Hand tighten bolts No. 6 and No. 7 to a torque of 90 ± 5 N·m (66 ± 4 lb.ft.).
e. Hand tighten each bolt an additional 90 ± 5°.
6. Remove the rod cap and measure the Plastigage. The rod bearing clearance must be 0.107 to 0.218 mm (.0042 to .0086 in.).
7. Put Fel-Pro C100 Lubricant on the bolt threads and contact surfaces of the bolts and caps before final assembly. Put clean engine oil on both halves of the rod bearings. Put caps (2) in position, and tighten the bolts as in Steps 5a through 5d. An impact wrench can be used for the final tighten torque of 90 ± 5° in Step 5e.
