START BY:
a. remove oil pan
1. Turn the crankshaft until two pistons are at bottom center. Remove nuts (1) and connecting rod caps (2) from the two connecting rods. Remove the lower half of the bearings from the caps.
2. Push the connecting rods away from the crankshaft, and remove the upper half of the bearings.
| NOTICE |
|---|
Be careful not to damage the crankshaft journals. Do not turn the crankshaft while any of the connecting rod caps are removed. Do not put oil on the bearings until after the bearing clearance is checked. |
3. Clean the surfaces where the bearings fit. Install the upper half of the new bearings in the rods. Put the connecting rods in position on the crankshaft.
4. Clean the surfaces where the bearings fit. Install the lower half of the new bearings in the caps without oil. Put 2P2506 Thread Lubricant on the bolt threads and contact surfaces of the nuts.
| NOTICE |
|---|
When the connecting rod caps are installed, make sure that the numbers on the side of the caps are next to and respective with the number on the side of the connecting rods. Do not use an air impact wrench to tighten the nuts on the caps. |
NOTE: For complete details concerning measuring bearing clearances, see Engine Bearings And Crankshafts, Form No. SEBD0531.
5. Check the bearing clearance with Plastigage (A). Put the caps in position on the connecting rods, and install the nuts. Tighten the nuts to a torque of 41 ± 4 N·m (30 ± 3 lb.ft.). Put a mark on each nut and the end of each bolt. Tighten the nuts 60° ± 5° more.
6. Remove the cap. Measure the width of the Plastigage. The rod bearing clearance must be 0.043 to 0.140 mm (.0017 to .0055 in.). The maximum permissible clearance must not be more than 0.15 mm (.006 in.).
7. Put clean SAE 30 oil on the bearings and crankshaft jounals. Put caps (2) in position on the connecting rods, and install the nuts. Tighten the nuts to a torque of 41 ± 4 N·m (30 ± 3 lb.ft.). Put a mark on each nut and the end of each bolt. Tighten the nuts 60° ± 5° more.
8. Do Steps 1 through 7 again for the other bearings.
