Crankshaft and Connecting Rods
Crankshaft Main Journal Diameter
Standard: 34.984 ∼ 35.000 mm (1.3773 ∼ 1.3780 in.)
Service Limit: 34.96 mm (1.376 in.)
If any journal has worn past the service limit, replace the
crankshaft with a new one.
If the measured journal diameters [A] are not less than the
service limit, but do not coincide with the original diameter
markings [B] on the crankshaft, make new marks on it.
Crankshaft Main Journal Diameter Marks
None 34.984 ∼ 34.992 mm (1.3773 ∼ 1.3776 in.)
1 34.993 ∼ 35.000 mm (1.3777 ∼ 1.3780 in.)
□: Crankshaft Main Journal Diameter Marks, “1” or no
mark.
• Measure the main bearing inside diameter, and mark the
upper crankcase half in accordance with the inside diam-
eter.
Crankcase Main Bearing Inside Diameter Marks: “○” or
no mark.
• Tighten the crankcase bolts to the specified torque (see
Crankcase Assembly).
NOTE
○The mark already on the upper crankcase half should
almost coincide with the measurement.
Crankcase Main Bearing Inside Diameter Marks
○ 38.000 ∼ 38.008 mm (1.4961 ∼ 1.4963 in.)
None 38.009 ∼ 38.016 mm (1.4964 ∼ 1.4967 in.)
• Select the proper bearing insert [A] in accordance with the
