Connecting Rod: Notes
- Check the connecting rod side clearance.
Using a feeler gauge, measure the end play while moving the connecting rod back and forth.
- If out-of-tolerance, install a new connecting rod.
- If still out-of-tolerance, replace the crankshaft.
Side clearance
Standard: 0.10 - 0.25 mm (0.0039 - 0.0098 in.)
- Check the connecting road bearing oil clearance.
- Check the match marks on the connecting rod and cap are aligned to ensure correct reassembly.
- Remove 2 connecting rod cap bolts.
- Remove the connecting rod cap and lower bearing.
- Clean the crank pin and bearing.
- Place a plastigage across the crankshaft pin journal.
- Reinstall the lower bearing and cap, and torque the bolts.
Tightening torque
1st step:
17.7-21.6 N.m (1.8-2.2 kgf-m, 13.0 - 15.9 lb-ft)
2nd step: 88-92°
NOTE:- Do not turn the crankshaft.
- Always use new connecting rod cap bolts. Connecting rod cap bolts are torque-to-yield bolts designed to be permanently elongated beyond the state of elasticity when torqued, so if the bolts are removed and reused, it may cause the bolts to break or fail to maintain clamping force.
- Remove the connecting rod cap and lower bearing.
- Measure the width of the plastigage at its widest point.
Oil clearance:
0.028 - 0.046 mm (0.00110 - 0.00181 in.)
- If the measurement from the plastigage is too wide or too narrow, remove the upper and lower bearing and then install new bearings with the same color mark. Recheck the oil clearance.NOTE: Do not file, shim, of scrape the bearings or the caps to adjust clearance.
- If the plastigage shows the clearance is still incorrect, try the next larger or smaller bearing. Recheck the oil clearance.NOTE: If the proper clearance cannot be obtained by using the appropriate larger or smaller bearings, replace the crankshaft and repeat the check procedure.NOTE: If the marks are indecipherable because of an accumulation of dirt and dust, do not scrub them with a wire brush or scraper. Clean them only with solvent or detergent.
