Crankshaft inspection
1. Inspect the crankshaft journals for galling, scoring,
pitting or any other form of damage.
2. Measure the journals at the bearing contact points
using a vernier caliper or a micrometer. See Figure
10.8.
3. Inspect the crankpin for galling, scoring, pitting or
any other form of damage.
4. Measure the crankpin using a vernier caliper or a
micrometer. See Figure 10.9.
5. Check the crankshaft for straightness by measuring
the run out. The crankshaft run out can be checked
by:
5a. Place the crankshaft on a pair of matched V-
blocks or in the engine block with the sump
installed.
5b. Place a dial indicator at a smooth point at either
end of the crankshaft.
5c. Slowly turn the crankshaft while watching the
dial indicator.
NOTE: Stop the crankshaft before the dial indicator
hits the keyway.
5d. Compare the reading on the dial indicator to the
specification listed at the end of this chapter.
5e. Repeat the above steps on the other end of the
crankshaft.
6. Inspect the timing gear for wear or damage.
NOTE: The timing gear can be removed from the
crankshaft and replaced if worn or damaged.
See Figure 10.10.
