PRECAUTIONS

• WATER & ELECTRONICS DON’T MIX Never allow water, moisture, or

other foreign materials to get inside motor, or on PCBs.

• CHECK MOTOR SCREWS Remember to check all motor screws

for loosening after a few runs of the motor.

• INSULATE WIRES Always insulate exposed wiring with heat shrink

tubing to prevent short circuits.

• NO SOLVENTS Do NOT expose the motor to any type of solvents.
• MOTOR CAPACITORS Brush motors generate electrical noise. Use

all 3 capacitors on the motor to help prevent radio interference.

• NO SCHOTTKY DIODES WITH REVERSIBLE ESCs NEVER use Schottky

diodes on the motor with reversible ESCs--ESC damage will occur.

• SET GEAR MESH PROPERLY Too tight of a gear mesh can result

in motor pinion shaft breakage--be sure to adjust mesh properly.

MOTOR MAINTENANCE

• CHECK MOTOR SCREWS

Check all motor screws for loosening at regular intervals, just like

other hardware on your vehicle.

• CHECK MOTOR BEARING & BRUSH WEAR

After extensive use, your motor’s bearings or commutation brushes

may need replacement. A small drop of light oil on the bearings

periodically can help extend bearing life--however, too much oil will

attract dirt and will cause problems, so apply sparingly & wipe clean.

• CLEAN INSIDE MOTOR

Periodically remove the end bell of your motor, remove the rotor,

and blow out the inside of the motor with compressed air. Be sure

not to lose any small shim washers that may be on the shaft ends &

keep them in the correct location.

INSTALLATION INSTRUCTIONS

1. CHECK MOTOR SCREW LENGTH & INSTALL MOTOR

• Insert the M3 motor mounting screws that came with your

vehicle through the motor mounting plate.

You need no more

than 1/8” of screw extending past the vehicle’s mounting plate

(2-4mm)--Too little can strip the motor’s threads, too much may

cause internal motor damage & will void warranty.

• Attach motor to vehicle’s motor mount using one of the sets of

threaded mounting holes--

select a mounting position that keeps the

wire tabs clear of conductive surfaces like aluminum or graphite.

2. INSTALL PINION GEAR

Install pinion on motor and align pinion and spur gears. Tighten

pinion’s set screw on the flat of motor shaft.

3. ADJUST MOTOR FOR PROPER GEAR MESH

• Adjust the motor position for proper amount of free play. You

NEED a small amount of play between the pinion gear and

the spur gear (about the thickness of piece of paper)--check the

free play at several positions around the spur gear to ensure

a proper mesh

(just in case the gears are out of round).

MAKE SURE THE PINION/SPUR GEAR MESH IS NOT TOO TIGHT!

If gear mesh is too tight, motor shaft breakage can occur.

• Tighten motor mounting screws--Avoid using excessive force

that could break screws or strip the threaded holes in motor.

4. SOLDER MOTOR POWER WIRES

• Determine the best routing in vehicle for power wires. Prepare

ends of motor power wires by stripping 1/8-1/4” of insulation

from end of wire. Tin wire ends with solder.

•

Lay tinned end of the wire flat on the solder tab and solder

wires to proper tabs of the motor. Apply heat with soldering

iron to the power wire and solder tab--begin adding solder to

tip of iron and to wire--

Add just enough solder to form a clean

& continuous joint from the solder tab up onto the wire.
