Such misalignment may cause a crankshaft hard
to be manually turned. Verification can be done by
measuring deflection each end of crankshaft.
If deflection is found greater than specified toler-
ance, this indicates worn bearing(s), bent and/or
disaligned crankshaft. Proceed with the disassem-
bly of the engine.
Disassembled Engine
The following verifications can be performed with
the engine disassembled.
Crankcase
Inspect plane surfaces for warpage. Small defor-
mation can be corrected by grinding surface with
a fine sandpaper. Install sandpaper on a surface
plate and rub part against oiled sand paper.
Bearing
Inspect crankshaft bearings
no. 4
. Check for cor-
rosion, scoring, pitting, chipping or other evidence
of wear. Make sure plastic cage is not melted. Ro-
tate and make sure they turn smoothly.
Crankshaft
NOTE:
If crankshaft and/or components are found
defective, it must be repaired by a specialized
shop or replaced.
