MSD APS Starter, Chevrolet SB and BB V8
Straight Mount, PN 5095
Staggered Mount, PN 50951
WARNING: Before installing the APS Starter disconnect the
battery cables. When disconnecting the battery
cables, always remove the Negative (-) cable
first and install it last.
IMPORTANT: Proper installation of the APS Starter is important to the overall operation. Correct alignment of
the starter pinion with the ring gear is needed to achieve the best operation and longevity from
your starter. Please read the instructions before attempting the installation.
1. Make sure the starter mounting flange on the engine block
is clean and smooth.
2. Install the starter with the supplied hardware. It is recommended
to leave the shims out until the pinion gear to ring gear teeth
mesh is checked. Torque the bolts to 32 lb-ft.
3. Check that the position of the solenoid is away from direct
heat sources and other components. If there are clearance
problems, the starter housing can be rotated to move the
location of the solenoid. This is done by removing the three
bolts on the mounting block and repositioning the starter
motor (Figure 1).
4. With the starter installed, check the clearance between the ring
gear and the edge of the pinion gear (Figure 2). There should
be at least 1/16". It is recommended to check this clearance
in at least three places around the flex plate.
• If there is not enough clearance, you will need to install
the supplied shim kit by removing the mounting block
(Figure 3). Place the small shim ring in the bearing bore
and install the outer shim on the support housing. Reinstall
the mounting block. This will move the pinion gear into the
starter approximately 0.060".
