#55-3556-1 Rev.C

Printed 2-2014

PRECAUTIONS

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

or other foreign materials to get inside 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. Install

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 BUSHINGS & BRUSH WEAR

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

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

periodically can help extend bushing life–however, too much oil will

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

• CLEAN INSIDE MOTOR

Periodically blow out the inside of the motor with compressed air.

INSTALLATION INSTRUCTIONS

1. INSTALL MOTOR CAPACITORS

Electric motors generate RF noise that causes interference. The

included 0.1µF (50V) [Novak #5620] non-polarized, ceramic

capacitors must be used on all Terra Claw motors to reduce

motor noise and prevent ESC damage.

Solder 0.1µF (50V) capacitors between:

• POSITIVE (+) motor tab & NEGATIVE (–) motor tab.
• POSITIVE (+) motor tab & Motor Can
• NEGATIVE (–) motor tab & Motor Can

Positive (+) motor tab
Grounded motor capacitors
0.1µF Capacitors
Negative (-) motor tab
Motor can

Make sure NOT to touch motor capacitor leads

to motor can, except for the two motor

capacitors that are grounded to the can.

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 a 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 GEAR MESH BETWEEN THE

PINION & SPUR GEARS 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.

PRODUCT WARRANTY

Novak products are guaranteed to be free from defects in materials or

workmanship for a period of 120 days from the original date of purchase

(verified by dated, itemized sales receipt). Warranty does not cover incorrect

installation, components worn by use, cross-connection of battery/motor

power wires, overheating solder tabs, damage resulting from overload, wear

or damage from improper gear mesh or damage from disassembling motor,

tampering with motor, allowing water, moisture, or any other foreign material

to enter motor, allowing exposed wiring or solder tabs to short-circuit, or any

damage caused by a crash, flooding, or natural disaster. In no case shall our

liability exceed the product’s original cost. We reserve the right to modify

warranty provisions without notice.
Because Novak R/C, Inc. has no control over the connection & use of motor

or other related electronics, no liability may be assumed nor will be accepted

for damage resulting from the use of this product. Every motor is tested before

leaving our facility and is, therefore, considered operational.
By the act of connecting motor to speed control or operating motor, the user

accepts all resulting liability.
