User Manual

IMPORTANT: To prevent pinion slippage,
verify motor shaft has a flat area where
indicated to capture the set screw. Some
motors will not have this, use a dremel to
add a small flat area.
IMPORTANT STEPS:
1. Install pinion on the motor shaft but
do NOT tighten the M4 set screw at
this step.
2. Install the motor and bearing block
using the indicated hardware.
3. Temporarily tighten the motor and
bearing block.
4. Verify the pinion is in contact with
the support bearing, then secure M4
set screw using RED threadlocker.
Verify that the set screw is in full
contact with shaft flat area.
5. Loosen all motor and bearing block
bolts to set appropriate gear mesh.
Allow minimal backlash without
binding of the main gear.
IMPORTANT: When securing the
motor, verify motor bolts do not
penetrate the stator wires or internal
damage to the motor may occur.
External motor shaft should be at least
31mm to engage support bearing.
