(i) Remove the eight bolts and main bearing cap.
(See procedure (a) and (b) above)
(j) Measure the Plastigage at its widest point.
Standard clearance:
STD 0.029–0.056 mm
(0.0011–0.0022 in.)
U/S 0.25 0.028–0.080 mm
(0.0011–0.0031 in.)
Maximum clearance: 0.08 mm (0.0031 in.)
HINT: If replacing the cylinder block subassembly, the bear-
ing standard clearance will be:
0.031–0.067 mm (0.0012–0.0026 in.)
If the oil clearance is greater than maximum, replace the
bearings. If necessary, grind or replace the crankshaft.
HINT: If using a standard bearing, replace with one having
the same number. If the number of the bearing cannot be de-
termined, select the correct bearing by adding together the
numbers imprinted on the cylinder block and crankshaft, then
selecting the bearing with the same number as the total.
There are five sizes of standard bearings, marked “1”, “2”, “3”,
“4” and “5” accordingly.
Number marked
Cylinder block 1 2 3
Crankshaft 0 1 2 0 1 2 0 1 2
Bearing 1 2 3 2 3 4 3 4 5
EXAMPLE: Cylinder block “2” + Crankshaft “1”
= Total number (Use Bearing “3”)
