INSTALLING THE PICKUP

the two fine thread bolts (Figure 1). The mount
retainer will only install one way, do not try to
force the bolts in. Hand tighten the bolts.
2. Install the bracket onto the engine. The bracket
is designed to be used on either side of the
balancer. Be sure to use the correct length bolts
and spacers in the proper locations.
3. Install the pickup and locknut into the holder. Do
not tighten the locknut at this time.
INSTALLING THE TRIGGER WHEEL
The trigger wheel is designed so it can be used on engines with a dry sump oiling system as well as
stock dampers. Two centering rings are included; one for use on stock or most aftermarket dampers
and one for use with a dry sump pump drive mandrel (Figure 2).
