Crankshaft Inspection
NOTE: The crankshaft for a unitized (clockwise) engine has left-hand threads at the clutch mounting hole,
and there is a machined groove in the outside diameter of the counterweight as shown below (Fig-
ure 13-82, Page 13-39).
1. Clean and inspect the journals for scoring. Inspect the crankshaft gear for cracks, scoring or broken
teeth. Replace parts if necessary.
2. Using a micrometer, measure both main journals (PTO side and flywheel side) at several points along
their lengths (Figure 13-83, Page 13-39).
3. If either journal diameter is less than 1.3751 inches (34.930 mm), replace the crankshaft.
4. Using a micrometer, measure the connecting rod journal at several points along its length (Figure 13-
5. If the journal diameter is less than 1.4741 inches (37.444 mm), replace the crankshaft.
6. Using a micrometer, measure the crankshaft link rod journals at several points (Figure 13-85, Page 13-39).
7. If the diameter of either journal is less than 1.9655 inches (49.924 mm), replace the crankshaft.
