NOTE: This procedure is for selecting bearings using a new crankshaft.
Select the crankshaft main bearings for each crankshaft journal.
- Read the code on the crankshaft flange.
- Read the code on the cylinder block face.
- The first letter after the first asterisk makes up the code for main No. 1 and the next letter for main No. 2. The first letter after the second asterisk makes up the code for main No. 3 and the last letter for main No. 4.
- Using the chart, choose a bearing for each main. Match the block and crankshaft code with its corresponding column or row, by reading across the "crankshaft" row and down the "block" column.
- If the block code is *BM*QS* and the crankshaft code is *OL*PO*, Main No. 1 should be built with grade 1 bearings, as determined by the intersection of the B block column and the O crankshaft row on the chart. Mains No. 2, No. 3 and No. 4 should all be grade 2.
-
NOTE: The rod cap installation must keep the same orientation as marked during disassembly or engine damage may occur.
Using the original connecting rod cap bolts, install the connecting rod caps and bolts.
- Tighten the bolts in 3 stages.
- Stage 1: Tighten to 23 Nm (17 lb-ft).
- Stage 2: Tighten to 43 Nm (32 lb-ft).
- Stage 3: Tighten an additional 90 degrees.
- Measure the connecting rod large end bore in 2 directions.
- Remove the bolts and the rod cap.
- Discard the connecting rod cap bolts.
- Remove the bolts and the rod cap.
- Measure each of the crankshaft connecting rod bearing journal diameters in at least 2 directions.
- Using the chart, select the correct connecting rod bearings for each crankshaft connecting rod journal.
-
NOTE: Before assembling the cylinder block, all sealing surfaces must be free of chips, dirt, paint and foreign material. Also, make sure the coolant and oil passages are clear.
Lubricate the upper crankshaft main bearings with clean engine oil and install the 4 crankshaft main bearings in the cylinder block.
-
NOTE: Do not install the upper thrust bearings until the crankshaft is installed.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
