Remove And Install Connecting Rod Bearings
start by: a) remove oil pump1. Check the connecting rods and caps for their identification and location.2. Turn crankshaft until connecting rod caps are in position shown. 3. Remove the nuts (1) and the cap from connecting rod. Remove lower half of bearing from cap.4. Push the connecting rod away from the crankshaft. Remove the upper half of bearing from connecting rod. 5. Install upper half of bearing in connecting rod. Put clean engine oil on bearing and on crankshaft journal.6. Pull the connecting rod slowly on to the crankshaft.7. Install lower half of bearing in cap. Be sure the tabs in back of bearings are in the tab grooves of connecting rod and cap. 8. Use wire (A) to check bearing clearance.9. Put wire (A) on the bearing.10. Put 2P2506 Thread Lubricant on threads of rod bolts and seat surfaces of nuts. Be sure the cylinder numbers on the rod cap and rod are the same, and are on the same side of the connecting rod. Numbers are on the same side of rod and cap as are the grooves for the bearing tabs. If new rods are installed, put the cylinder number on the rod and cap. 11. Install the rod caps (2). Install the nuts. Tighten each nut to a torque of 60 6 lb.ft. (80 8 N m). Put a mark on the nuts and cap and tighten nuts an extra 120° 5° from the mark. Remove the rod cap. Remove wire (A) and check the bearing clearance. The bearing clearance must be .0028 to .0066 in. (0.071 to 0.168 mm) for new bearings. Maximum clearance with used bearings is .010 in. (0.25 mm).12. Put clean engine oil on lower half of bearing. Install rod cap again. Tighten each nut to a torque of 60 6 lb.ft. (80 8 N m). Put a mark on nuts and cap and tighten nuts an extra 120° 5° from mark.13. Do Steps 1 through 12 for the remainder of the connecting rod bearings.end by:a) install oil pump
