9-2.2. Magneto Coil Installation
CAUTION: After coil installation, verify the coil clamps secure the
coil tightly against the pole shoes in housing. If there is any play at
this point, wear will occur, the parts will loosen, and magneto output
will be degraded.
1. Position the coil (Figure 1) (58) in the magneto housing (50) so the coil primary lead
fits in the provided slot in the housing.
2. Replace coil core clamps (57) that do not match the illustration in Figure 7-11.
3. Secure one side of the coil in the magneto housing with a screw w/lock washer (56)
and coil core clamp (57). Sandwich the ground lead terminal between a screw w/
lock washer (56) and coil core clamp (57) and fasten the ground lead terminal to the
magneto housing with the screw w/lock washer.
4. Tighten screws (56) to 20 to 30 in-lbs. of torque. Press the coil primary lead into the
slot in the housing.
9-2.3. Distributor Block and Gear Assembly
1. If tower springs (Figure 1) (80) require replacement, use the 11-8627 Spring Seating
Kit. Insert the Spring Insertion Guide in the distributor block (79) tower outlet hole
as shown in Figure 9-6. Place contact spring (80), large end down, in the top of the
guide. Position the Plunger Assembly with the Handle attached, over the small end
of the spring, pushing the spring in to the tower, while turning the handle counterclockwise to seat the spring in the recess of the distributor block tower (79). The
spring is properly installed when the bottom turn of the spring is caught in the
distributor block bushing and the top turn of the spring is approximately centered in
tower outlet. Check spring height according to Section 7-2.4, step 6.
