Remove And Install Connecting Rod Bearings
start by:a) remove piston cooling jets1. 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 bearings from caps (2).3. Push the connecting rods away from the crankshaft and remove the upper halves of the bearings from the rods. 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). Put 2P2506 Thread Lubricant on the bolt threads and contact surfaces of the bolts and caps. 5. Make a check of 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:
Do not use an impact wrench to tighten the bolts the additional 90 5° of a turn more.
Bolts (6) and (7) are on the end of the rod cap opposite the end that has the location pin for correct installation. a) Tighten bolts No. 4 and 5 to a torque of 90 5 N m (65 4 lb.ft.).b) Tighten bolts No. 6 and 7 to a torque of 90 5 N m (65 4 lb.ft.).c) Tighten bolts No. 6 and 7 again to a torque of 90 5 N m (65 4 lb.ft.).d) Tighten each bolt 90 5° of a turn more.6. Remove the cap and measure the Plastigage. The rod bearing clearance must be 0.107 to 0.218 mm (.0042 to .0086 in.).7. Put clean engine oil on both halves of the rod bearings. Put caps (2) in position and tighten the bolts as in Step 5.end by:a) install piston cooling jets
