Connecting Rod: Procedures
INSPECTION
PISTONS
1. Check piston pin bores in piston for roundness. Make 3 checks at 120° intervals. Maximum out of roundness.020 mm (.0008 in.).
2. The piston diameter should be measured approximately 10mm (.394 in.) up from the base.
3. Skirt wear should not exceed 0.1 mm (.00039 in.).
4. The clearance between the cylinder liner and piston should not exceed 0.010-0.022 mm (.0003 -.0008 in.).
PISTON PINS
1. Measure the diameter of piston pin in the center and both ends.
CONNECTING RODS
CAUTION: Connecting rods must be replaced once the end caps are loosened. All six must have the same weight and the same number.
Replacement connecting rods will only be supplied in sets of six. When assembling the connecting rod, be sure to paint mark or scribe
mark each of the connecting rods and caps before installation, for alignment purposes later.
NOTE: Do Not lubricate the new connecting rod bolts. They are already coated with a anti scuff treatment.
Connecting rods are supplied in sets of six since they all must be of the same weight category. Max allowable weight difference is 5 gr.
1. Assemble bearing shells and bearing caps to their respective connecting rods ensuring that the serrations on the cap and reference marks are
aligned.
2. Tighten connecting cap bolts to 20 Nm (15 ft. lbs.).
3. Without loosening connecting rod bolts, tighten all bolts to 40 Nm (30 ft.lbs.).
4. Using a torque angle gauge, tighten each bolt an additional 90°.
