Tightening torque:
31-39 N.m (3.2-3.8 kgfam, 23-28 ftlbf)
(7) Remove the connecting rod cap.
(8) Measure the Plastigage at each journal at the widest
point for the smallest clearance, and the narrowest
point for the largest clearance.
I
Oil clearance
Standard: 0.025-0.035mm (0.001 0 4 . 0 0 1 4 in)
Allowable: 0.020--0.066mm (0.0008-0.0025 in)
(9) If the oil clearance exceeds the maximum, grind the
crankshaft and install undersize bearings.
2. Install the connecting rod bearings and caps as follows:
(1) Remove the Plastigage from the journals and bear-
ings.
(2) Apply a liberal amount of clean engine oil to the

rod bearing seats on the crankshaft journal.
(5) Make sure the connecting rod is seated correctly on
the crankshaft journal. Install the cap and bearing
assembly and tighten the nuts.
Tightening torque:
31-39 N-m (3.2-3.8 kgf.m, 23-28 ft.lbf)
3. After the piston and connecting rod assemblies have been
installed, check the side clearance between the connect-
ing rods on each crankshaft journal.
Side clearance
Standard: 0.1 5 4 . 3 5 m m (0.0064.01 4 in)
