Information:

Start By:a. remove piston cooling jetb. remove oil pan1. Use tool (A), and turn the engine flywheel to move the connecting rod cap bolts into a position for removal. 2. Remove bolts (1) and bearing cap (2). Remove the lower half of the bearing from cap (2).3. Push the connecting rod away from the crankshaft, and remove the upper half of the bearing from the rod. Install rod bearings dry when the clearance checks are made. Put clean engine oil on the rod bearings for final assembly.
Be sure the tabs in the back of the connecting rod bearings are in the tab grooves of the connecting rod and cap.
4. Clean the surfaces where the bearing halves fit. Install bearing halves (3) in the rod and cap (2). The serviceman must be very careful to use Plastigage, tool (B) correctly. The following points must be remembered:...Make sure that the backs of the bearings and the bores are clean and dry....Make sure that the bearing locking tabs are properly seated in their slots....The crankshaft must be free of oil where the Plastigage touches it....Put a piece of Plastigage on the crown of the bearing half that is in the cap. Do not allow the Plastigage to extend over the edge of the bearing....Install the bearing cap using the correct torque-turn specifications. Do not use an impact wrench. Be careful not to dislodge the bearing when the cap is installed....Do not turn the crankshaft with the Plastigage installed....Carefully remove the cap but do not remove the Plastigage. Measure the width of the Plastigage while it is in the bearing cap or on the crankshaft journal. Do this by using the correct scale on the package. Record the measurements....Remove the Plastigage before reinstalling the cap.When using Plastigage, the readings can sometimes be unclear. For example, all parts of the Plastigage are not the same width. Measure the major widths to make sure that they are within the specification range. Also, experience has shown that when checking clearances tighter than 0.10 mm (.004 in) the readings may be low by 0.013 to 0.025 mm (.0005 to .0010 in). Out-of-round journals can give faulty readings. Also, journal taper may be indicated when one end of the Plastigage is wider that the other.For complete details concerning measuring bearing clearances, see Engine Bearings And Crankshafts, Form No. SEBD0531. 5. Check the bearing clearance with Plastigage. Put cap (2) in position on the connecting rod, 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: 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. Put Fel-pro C100 Lubricant (if not available, use 2P2506 Thread Lubricant) on the bolt threads and contact surfaces of the
