Crankshaft Front Oil Seal Removal -- Continued.
NOTE
The flange of the crankshaft seal replacer is .315 inches (in) (8 millimeters (mm)) thick.
5. Apply marking tape to 9/64-in drill bit at a depth of .71 in (18 mm).
6. Apply grease to drill bit to catch metal shavings.
CAUTION
Carefully drill a straight hole to reduce the possibility of damage to the front gear cover and
crankshaft. Failure to comply may cause damage to equipment.
7. Drill one hole 0.39 in (10 mm) deep into crankshaft front oil seal (Figure 1, Item 4) until tape mark on drill bit
reaches crankshaft seal replacer (Figure 3, Item 1) flange.
8. Ensure marking tape has not moved from original position.
9. Install one sheet metal screw (Figure 3, Item 2), found in crankshaft oil seal replacement kit, through
crankshaft seal replacer (Figure 3, Item 1) flange and into crankshaft front oil seal (Figure 1, Item 4) to hold
crankshaft seal replacer (Figure 3, Item 1) in position.
NOTE
Ensure all six sheet metal screws are threaded through both the inner and outer seal casings.
Sheet metal screws need to be uniformly tightened in order to simultaneously remove the inner
and outer casings of the crankshaft front oil seal.
10. Drill remaining five holes 0.39 in (10 mm) deep, and install five sheet metal screws (Figure 3, Item 2) into oil
seal.
