Tilt Piston Identification
Two of the piston relief holes are small, the oth er
two holes are larger. Two of the springs have five
coils and the other two have nine coils. On assem-
bly, the two five-coil springs go in the la rge relief
holes, and the two nine-coil springs go in the small
relief holes.
Tilt Piston Assembly
Piston ch eck balls and plu ngers are identical.
Lubricate and install a new outer O-ring on the tilt
piston. Place one ball, on e plunge r, an d on e
spring in each hole in the piston as indicated.
The two five-coil springs go in the la rge relief
holes and the two nine-coil springs go in the small
relief holes. Set the piston aside.
