ROTOR REPLACEMENT INSTRUCTIONS:
1. Remove motor from vehicle & brush off any dirt (do not use motor cleaner).
2. Remove the front end bell/can/cap (end section of motor on the same side
as the pinion shaft) using a hex wrench to remove the three long socket
head cap screws. The front end bell/can/cap will then slide off the motor.
Be sure to keep track of front insulator disc.
3. Remove old rotor by grasping pinion shaft with pliers and pulling it
straight out of the motor.
Note: The rotor is the magnet in brushless motors and will attract metallic objects
(wrenches, washers, etc.)--place rotor on a soft cloth or towel to prevent damage.
–Most Novak motors have shim washers on the pinion end (& sometimes on
the back end) of the rotor to adjust free play-- Do Not lose these & re-install
them on the correct side of rotor. Washers may be stuck to the bearing.
–Older SS series motors have brass spacers on both sides of rotor between
magnet & bearings-- Do not lose them & re-install them on the correct sides.
4. Clean inside motor using compressed air. (NO solvents or spray cleaners).
5. Install new rotor:
Rotors with Nickel-Plated Magnets
–Use a rolled-up piece of a business card inserted down into the center
of the stator to help align and insert rotor (or the clear tube some new
rotors come packaged in if it fits in the stator).
–Make sure the shim washers are on the correct sides of the rotor, just
as they were positioned on the original rotor.
–While holding the new rotor’s shaft on the pinion end with a pair of
needle nose pliers, carefully insert rotor down into motor. Once the rotor
is seated in the back bearing, remove the rolled paper/tube from motor.
Take extra care when inserting the new rotor into the motor, as the
high strength of the rotor will pull it into the motor with great force,
and will easily damage the sensor assembly inside the motor.
Older SS-Series/Velociti Rotors without Nickel Plating
Make sure the shim washers or brass spacers are on the correct sides
of the rotor, just as they were removed from the original rotor (shorter
brass spacer goes on the pinion side in the SS-series motors).
Take care not to damage the new rotor while it is being inserted into the
motor, as it will be magnetically attracted to the sides during assembly.
6. Replace insulator in front end bell if it was removed in Step 2.
7. Replace front end bell/can/cap by inserting the 3 long socket cap
screws into the holes of the front end bell/can/cap, aligning the screws
with the slots in stator, and threading them into the tapped holes in the
back end bell/ring-- Check that rotor spins freely as tightening screws--If
binding occurs, disassemble motor and determine cause. If it turns freely,
firmly tighten the screws.
If screws do not have a patch of locking agent on threads, add a small drop to tips.
8. Re-check screw tension after the first couple runs--It is common for the
vibration and heating to allow parts to settle. Check all 6 main screws.
PRODUCT WARRANTY: Novak Electronics, Inc. guarantees all products 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, damage resulting from thermal overload or use of excessive timing, physical damage
from being dropped, corrosion, abrasion from any foreign materials, or any damage caused by
a crash, flooding, or other natural disaster. In no case shall our liability exceed the product’s
original cost. We reserve the right to modify warranty provisions without notice.
