Connection Rod Inspection
Measure big end oil clearance.
NOTE: Do not move crankshaft or connect-
ing rods until measurement process is com-
pleted.
1. Remove lower connecting rod caps.
2. Place a piece of Plastigauge across
the
journal
surface. Install lower rod caps with journal bearings
installed.
3. Torque rod bolts to specified torque.
4. Remove caps and measure each compressed piece of
Plastigauge .
5. Reference bearing replacement guide if bearing oil
clearance is out of specification.
•
Out of specification: Replace connecting rod bearings
Measure small end inside diameter.
•
Out of specification: Replace connecting rod
Connecting Rod Bearing Replacement Guide
Replacement of the connecting rod bearings is required when the bearing oil clearance is out
of specification. Use this guide to select new bearings.
NOTE: Bearing color code is imprinted on the side of each bearing.
REPLACEMENT BEARING THICKNESS
RED
.0783 - .0785 (1.990 - 1.995mm)
YELLOW
.0785 - .0787 (1.995 - 2.000mm)
BLUE
.0787 - .0789 (2.000 - 2.005mm)
If the measured clearance is within specification, replace with new bearings with the same
color code.
If the used bearings reveal an oil clearance of .04 and .05mm, install new bearings with the
same color code.
