WARNING: Before installing the DynaForce 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 DynaForce High Speed Starter from MSD. The DynaForce 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 traditional DynaForce
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 DynaForce 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.
