Velineon 3500 Motor Rebuild Instructions
Note: During the production life of the Velineon 3500, cosmetic changes were made to the can and rotor. These cosmetic
changes in no way affect the performance of the motor, and with the use of specific sets of the included bushings (see
reverse), all the parts are interchangeable. Before you proceed with the instructions below, look at the front of your motor
to determine which style you have. Original style motors have four visible screws and a silver front end cap. Current style
motors have a solid front end cap with no screws (for your convenience, this package contains four extra end cap screws).
Tools needed
A1
1.5mm hex wrench
2.0mm hex wrench
Traxxas 4-way wrench
Phillips screwdriver
Plastic mallet
Adjustable wrench
Wood blocks
Disassembling the motor
1. Grip the motor with both hands and pop
the plastic end cap off of the motor with
your thumbs (D1).
2. Remove the four 2.5x5mm
screws from the wire side
(rear) end bell (D2). Pull
the end bell out of the
motor can (D3).
3. Remove the rotor and
metal bushing from the
rotor (D4). Discard the metal bushing. Your
rotor may or may not include a thin plastic
spacer. If this thin plastic spacer is present,
reuse it.* Note: The rotor contains a very
powerful Neodymium magnet and should be
kept away from any magnetic-based storage
devices, credit cards, monitors, etc.
Removing and installing the end bell bearings
1. Open an adjustable
wrench to approximately
¾" and lay it down on
your work surface. Place
the rear end bell "inside
down" on top of the
wrench with the bearing centered over the opening (D5). Tap
the bearing out using the 4-way wrench and a plastic mallet.
Repeat the process for the bearing on output shaft side of the
motor can (D6). Discard the old bearings.
2. Drop one of the included bearings down
into the motor can. Position it over the
recessed bearing boss inside the can.
Position an over-sized Phillips screwdriver
tip into the center of the bearing and work
it around until the bearing is settled evenly
into the motor can (D7).
Use a mallet to tap the
bearing the rest of the
way into the can.
3. Place the end bell
"outside down" on a
wood block. Place the new 5x11mm bearing in the end bell
housing. Place another wood block on top of the bearing and
tap the bearing into the end bell with a plastic mallet (D8). Make
sure the bearing is fully seated (D9).
Important Note: The ball bearings included with this kit are special
high-speed bearings designed for use with the high-performance
Velineon motor. Do not use standard bearings for this application.

Removing the motor
1. Remove the right rear wheel (passenger rear).
2. Remove the two 3x6mm screws from the gear cover. Remove
the gear cover (A1).
3. Loosen the motor pinion gear set screw (A2, circled) and slide
the gear off of the motor shaft. Disconnect the motor wires and
loosen the two 3x8mm screws (A2) until the motor is free of the
gearbox. Remove the motor.
Rotor Bushing Replacement
1. Install the bushing onto the rotor, and
then insert the rotor into the motor can
as shown.
2. Install the rear end bell onto the motor
can and secure it with the same four
2.5x5mm screws. Snap the end bell cap
back onto the motor can. The motor is
ready for installation.
3. Reinstall the motor in your vehicle. Set
the gear mesh by running a narrow strip
of notebook paper in between the gears.
With the motor screws loosened, slide
the motor and pinion gear into the spur
gear. Tighten the motor screws and then
remove the strip of paper.
4. Reinstall the gear cover and rear wheel.
5. Insert the bullet connectors into the electronic speed
control. Note the motor phase alignment.

* Motor Spacer Note: To achieve the correct
rotor end-play, your motor may have been
fitted with a thin spacer on the rotor shaft.
The spacer is installed at the factory only
if required, so your motor may not have
a spacer. If your motor is equipped with a
spacer, reinstall it when you reassemble the
motor. If your motor is not equipped with a
spacer, then it is not required and a spacer
should not be installed.
