Crankshaft/Balancer Shaft and Connection Rod
Crankshaft Removal
Split the crankcase (see Crankcase Disassembly).
Remove:
Transmission
Push the crankshaft out of the left crankcase half with a
press.
Crankshaft/Balancer Shaft Installation
Position the right crankcase half so that the right-hand
main bearing housing is seated on a suitable press fixture.
Press the crankshaft into the right-hand main bearing
housing.
Insert crankshaft jig [A] between the crankshaft halves,
opposite the crankpin, to prevent crankshaft distortion
during installation.
Special Tool - Crankshaft Jig: 57001-1174
Crankshaft Disassembly
CAUTION
Since assembly of the crankshaft demands exact-
ing tolerances, the disassembly and reassembly
of the crankshaft should only be performed by
experienced mechanics with the necessary tools
and equipment.
The crankshaft left main bearing, chain sprocket,
and left crankshaft are available separately as spare
parts, however, it is recommended that the crank-
shaft assembly be replaced rather than attempting
to replace the components.
Press the crankpin out of the crank halves to separate the
crank halves, connecting rod, spacers, crankpin needle
bearing, and crankpin.
Crankshaft Assembly
Apply engine oil to the needle bearing.
Press the crank halves onto the crankpin, noting the
crankpin direction until connecting rod side clearance is
within specification (see Connecting Rod Big End Side
Clearance).
Make sure oil passages of the crank and crankpin are
lined up during assembly.
Check that the connecting rod radial clearance is within
specification (see Connecting Rod Big End Radial Clear-
ance).
Adjust crankshaft runout until runout is within specification
(see Crankshaft Runout).
