MSD APS Starter
High Speed, Chevy 158/168 Tooth
PN 50952
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.
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).

Thank you for purchasing the APS High Speed Starter from MSD, PN 50952. This starter is designed
to replace the starter on GM engine blocks and will fit either standard or offset mounts. The APS
line of starters is specifically designed to start the engine time after time, even when it is very high
compression, hot, or has any other special circumstance that causes lesser made starters to fail.
Thanks to special gearing and other design features, the High Speed starter spins 25% faster than our
tradition APS starters. This extra speed is ideal for engines with magnetos or blown alcohol. Please
be sure to read, understand, and follow the instructions prior to installation so that everything goes
smoothly and the engine starts reliably time after time.
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.
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
