Block and Piston Inspection: Installation
- Piston/Connecting Rod Assembly

Push down on the ring compressor (B) to prevent the rings from expanding before entering the cylinder bore. 5. Stop after the ring compressor pops free, and check the connecting rod-to-rod journal alignment before pushing the piston into place.
- Crankshaft Assembly
1. Hold the crankshaft so rod journal No. 2 and rod journal No. 3 are straight up, and lower the crankshaft into the engine block. - Main Bearing Clearance - Inspection
1. Clean each main journal and bearing half with a clean shop towel.
2. Place one strip of plastigage across each main journal.
3. Reinstall the bearings and the lower block, then torque the bolts to 25 N.m (2.5 kgf.m, 18 lbf.ft) + 40° in the proper sequence.
NOTE:- Apply new engine oil to the bolt threads and flanges.
- Do not rotate the crankshaft during inspection.
4. Remove the lower block and the bearings again, and measure the widest part of the plastigage.
Main Bearing-to-Journal Oil Clearance Standard (New): 0.018-0.036 mm (0.00071-0.00142 in) Service Limit: 0.50 mm (0.00197 in) 5. If the plastigage measures too wide or too narrow, remove the crankshaft, and remove the upper half of the bearing. Install a new, complete bearing with the appropriate color code(s), and recheck the clearance. Do not file, shim, or scrape the bearings or the caps to adjust clearance.
6. If the plastigage shows the clearance is still incorrect, try the next larger or smaller bearing (the color listed above or below the current one), and check again. If the proper clearance cannot be obtained by using the appropriate larger or smaller bearings, replace the crankshaft, and start over.
- Crankshaft Bearing Selection
1. Numbers, letters, or bars have been stamped on the end of the engine block as a code for the size of each of the five main journal bores. Write down the crank bore codes.

5. If the plastigage shows the clearance is still incorrect, try the next larger or smaller bearing (the color listed above or below the current one), and check the clearance again. If the proper clearance cannot be obtained by using the appropriate larger or smaller bearings, replace the crankshaft, and start over.
