Power Unit Mechanical: 1D-60
8) Using scale on Plastigauge envelope, measure
plastigauge width at its widest point.
Crankshaft journal oil clearance
Standard: 0.016 – 0.036 mm (0.0012 – 0.0020 in.)
Service limit: 0.056 mm (0.0022 in.)
9) If measurement exceeds service limit, replace
crankshaft main bearing.
NOTE
For bearing replacement, see the “Selection
of Main Bearings” (Page 1D-60).
Selection of Main Bearings
Whenever a bearing requires replacement, select a new
bearing according to following procedure.
1) First, check journal diameter.
As shown in figure, upper (flywheel side) crank web
of No.1 cylinder has five stamped code numerals.
The numerals (1, 2 and 3) represent the journal
diameters shown below.
2) Next, check bearing holder inside diameter without
bearing.
As shown in figure, the cylinder block PORT side has
five stamped code letters or numerals.
The letters (A, B and C) or numerals (1, 2 and 3)
represent the bearing holder inside diameters shown
below.
3) There are five main bearings available, each of
differing thickness.
To distinguish them, a color mark is painted at the
position indicated in figure.
Each color represents the following thickness
measured at the center of the bearing.
