1.
Determine the best routing in the
vehicle for the motor’s sensor harness.
Securing the sensor harness to the
motor power wires with a tie-wrap can
provide a good location and also act as
a strain relief.
Novak offers several sensor
harness lengths for various installations
(
Novak #5351-5354
).
2.
Connect one end of the included
harness to the ESC and the other end
to the motor’s sensor harness connector
located on the back endbell (refer to
figure)- be sure to insert all the way.

!
GEAR SELECTION (Important!)
Motor operating temperature is the ONLY
way to properly set the maximum vehicle gearing
The motor should be
180°F (82°C) MAX
at end of run
!
Temperatures above 180°F will weaken the magnet & may
melt the coils! This voids warranty & can damage ESC!
Change the gearing to avoid overheating.
Because of the potential danger of overheating, ESC/motor
damage & failure, you must start with VERY small pinion
sizes and check ESC & motor temperatures at multiple times
throughout a run. This is the only way to ensure that you
are not causing excessive heating.
If ESC & motor temperatures remain low and stable, you can
slowly increase the pinion size while again monitoring the tem-
peratures to determine the safe gearing for your vehicle, motor,
and climate/track conditions. Because these variables can change
or be modified, you MUST continually monitor ESC and
motor temps to protect your electronics from damage.
OVERHEATING -- WARNING
!
The Novak HD8 Motor when used properly should not have an
issue of over-heating. However extended runtimes, gearing, ve-
hicle performance, and track conditions, can lead to overheating.
You must use extreme caution when setting up these
electronics and carefully test your application to avoid
overloading and overheating either the ESC or the motor.
Damage caused by excessive overheating WILL NOT be
covered under the product’s factory warranty.
Should any of the 28G Teflon wires pull out of the motor’s sensor
harness connector, re-insert them in the connector’s appropriate
slot. Check the plastic tab to make sure it has not deformed
excessively before inserting into the housing.

MOTOR MAINTENANCE
• CHECK ALL MOTOR SCREWS
for loosening at regular intervals,
just like other hardware on your vehicle.
Note: The 3 main
socket head screws that hold the motor together may require
tightening after a few runs of the motor.
Also check the 3 flat
head screws securing the end cap on the back of the motor.
If any of the motor screws are removed, it is important
to apply a thread locking agent for added strength.
• CHECK MOTOR BEARING WEAR
after extensive use. The
motor’s closed design will keep most dirt and debris out, but
some will get in and eventually cause wear. If the shaft does not
spin freely, you may need bearing replacement. A small drop
of
Novak Speed Lube (#5860)
on the bearings periodically
can help extend bearing life. However, too much oil will attract
dirt and will cause problems, so apply sparingly.
• CLEAN INSIDE MOTOR
periodically by removing front end
bell, removing the rotor, and blowing out the inside of the
motor with compressed air. Be sure not to lose any small shim
washers that may be on the ends of the rotor shaft, and keep
them in the correct location.

PRODUCT WARRANTY
Novak Brushless motors are guaranteed to be free from defects in materials or workmanship
for a period of one year 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
thermal overload or operation above 180°F, use of excessive timing or overheating, splices or
damage to the sensor harness, damage from disassembling motor, tampering with internal
electronics, allowing water, moisture, or any other foreign material to enter motor or get
onto the PC board, short-circuiting of motor by allowing exposed wiring or solder tabs to
cross-connect or ESC applying simultaneous power to more than one phase at a time from
switching to Brush Mode, free-revving motor, 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
