Subsection 09 (ENGINE MEASUREMENT)
Measuring in Crankcase
First, check deflection with crankshaft in
crankcase. If deflection exceeds the specified tol-
erance, recheck deflection using V-shaped blocks
to determine the defective part(s). See below.
Measuring on Bench
Once engine is disassembled, check crankshaft
deflection on V-shaped blocks. If deflection
exceeds the specified tolerance, it can be worn
bearings or a bent crankshaft. Remove crankshaft
bearings and check deflection again on V-shaped
blocks to determine the defective part(s). See
measurement “A” in following illustration.
