Step 6
This step requires you to drill a 3/8” hole in the
distributor housing to accommodate the new wiring
harness. Measure 1” from the existing insulator hole
and the same distance down from the top of the
housing and mark the distributor housing. You will be
slightly offset from the cap locating pin. With a paper
towel inside the housing for shavings, drill the 3/8”
hole now (Figure 8).
Step 7
Clean out any remaining metal shavings left from the
drilling operation using a vacuum, brush, etc. Do not
wash out the housing with the shaft assembly in
place or you will wash the lubrication out of the
centrifugal advance and cause it to fail. If necessary,
you can remove the shaft as an assembly then clean
out the housing.
Step 8
Lower the new plate assembly into the housing
(Figure 9). Use the vacuum advance arm to
determine the position. Tighten the 2 set screws,
reinstall the vacuum advance with the 2 external
screws. Reinstall the e-clip. Use Figure 10 for reference.
Step 9
Install the supplied grommet into the new hole you
drilled (Figure 11) and route the wiring as shown
in Figure 10.
