take the starter out, then remove the
three M6 x 1 mounting bolts
between
the
starter
and
the
mounting block and re-position
accordingly. Re-Torque to 8 ft-lbs.
Please see Figure 1. PLEASE
NOTE: Corvette applications are
particularly tightly packaged. Please
make sure the starter does not
contact any portion of the exhaust
manifold.
STEP 5. With the starter installed
and clocked at the best position,
check clearance between the faces
of the ring gear and pinion gear.
There should be at least 1/16”
(.0625”, 1.6mm) space between
gear faces. Please see Figure 2.
If there is not enough clearance,
you will need to install the included
shim
kit.
Remove
the
starter
assembly from the engine and
remove the mounting block. Install
the shim ring into the bearing bore,
place the outer shim on the starter
body, then re-assemble. This will
move the starter and pinion away
from the ring gear by approximately
1/16”. Please see Figure 3.
STEP 6. Connect the solenoid
switch wire. With the amperage
being considerable (~30A) to pull
the bendix, B&M recommends 12
Ga. wire as a minimum. PLEASE
NOTE: In Corvette applications, the
solenoid wire is extremely close to
the engine block. Please take
precautions in tightening the wire to
make sure it does not rotate and
contact the block.
STEP 7. Connect the main cable to
the starter. Due to the high
amperage required to turn the
starter motor, it is important to size
the wire in accordance to its length.
Keep in mind to size all ground
wires accordingly also, these are
carrying equal current. Please see
Table 1 for cable length versus gage
recommendations.
STEP 8. Reconnect the battery
terminals, starting with the positive
cable.
STEP 9. Start the engine. In order to
not exceed the duty cycle of the
starter, please do not operate the
starter for more than 30 seconds at
a time. Allow the starter to cool at
least two minutes between repeated
cycles.
