4. See Figure 22-5, "Helix Pattern Application." Apply helix using a strip of 180 grit emery cloth
approximately one half inch wide. Do approximately one quarter of the surface indicated at
a time, stroking the cloth outward toward the propeller flange in the direction of rotation
(CCW) towards you using maximum hand pressure. Reverse direction for left hand rotating
engines. This should result in a 30° pattern similar to that illustrated in Figure 22-5, "Helix
Pattern Application." After doing the first portion rotate crankshaft by hand to make next
portion available. Apply the same pattern again and continue completely around the
crankshaft in this manner.
1. Repeat cleaning operation.

Wrap spring around shaft in seal area. Turn spring ends in unwinding direction, then
join and allow one end to wind into the other end.

crankshaft with the recessed side toward the engine. Bring the ends of the seal back
together. With the spring ends opposite the seal split carefully work the spring into it's
recess in the seal.
4. Apply a thin coat of Permatex to outside diameter of seal.
5. Using thumb pressure, work seal into counterbore with the oil seal split at the 10 o'clock
or 2 o'clock position.
6. After seal is in place, wipe oil from seal and shaft.
7. Spray exposed portion, from which plating has been removed, with aluminum primer.
