CRANKSHAFT AND CONNECTING RODS
6. Measure:
• crankshaft journal bearing inside diameter
a
Out of specification
→
Replace the crank-
case assembly.
NOTE:
Measure the inside diameter of each crank-
shaft journal bearing at two places.
Crankshaft journal bearing inside
diameter
50.01 ~ 50.03 mm
(1.969 ~ 1.970 in)
7. Calculate:
• crankshaft journal-to-crankshaft journal
bearing clearance
Out of specification
→
Replace the crank-
shaft and crankshaft journal bearings as a
set.
NOTE:
Calculate the clearance by subtracting the
crankshaft journal diameter from the crank-
shaft journal bearing inside diameter.
Crankshaft journal-to-crankshaft
journal bearing clearance
0.030 ~ 0.062 mm
(0.0012 ~ 0.0024 in)
INSTALLING THE CONNECTING RODS
1. Lubricate:
• bolt threads and seats
(with the recommended lubricant)
Recommended lubricant
