(f) Install the upper main bearing on the cylinder block and crankshaft.
(g) Lay a strip of Plastigage across the main journals.
(h) Install the main bearing caps. Torque the cap bolts.
Torque: 1,040 kg·cm (75 ft·lb, 102 N·m)
HINT: Do not turn crankshaft.

(i) Remove the main bearing caps.
(j) Measure the Plastigage at its widest point.
Standard clearance: 0.030 — 0.048 mm
(0.0012 — 0.0019 in.)
Maximum clearance: 0.07 mm (0.0028 in.)
If the oil clearance is greater than maximum, replace the bearings. If necessary, replace the crankshaft.
Undersized bearing: U/S 0.25
HINT: If using a standard size bearing, replace with one having the same number. If the number of the bearing cannot be determined, select a bearing from the table below according to the numbers imprinted on the cylinder block and crankshaft. There are five sizes of standard bearings, marked "1", "2", "3", "4" and "5" accordingly.
