Motor Installation - Traxxas E Revo 5603 Owner's Manual

rock crawling, or racing on low traction surfaces. Note: Heavier oil
will allow power to be transferred even with one or more tires off the
ground. This can make the vehicle more likely to overturn.
From the factory, both the differentials are filled with SAE 30,000W
viscosity silicone oil. Only use silicone oil in the differentials. Traxxas
sells SAE 10,000W and SAE 50,000W viscosity oil (see your parts list). The
differentials have to be removed from the vehicle and disassembled to
change/replace oil.
Installing the Long Travel Rockers
Use the exploded views included with the model to aid in the installation
process. All of the rockers have labels identifying their proper location;
RF (right front), LF (left front), RR (right rear), and LR (left rear). Note: The
exhaust system must be removed to access the rear rocker arms.
1. Remove shock absorbers
Remove the screws that secure the shocks to the chassis shock mounts,
and to the rocker arms.
2. Install long travel shock springs
Replace all four of the 90mm travel shock springs with the four 120mm
long travel shock springs. The front shock springs are indicated by a
silver dot, and the rear shock springs are indicated by a blue dot.
3. Install long travel rockers
Replace the 90mm travel rockers with the long travel rockers by
removing the four 4x6 buttonhead cap screws from the rocker pivot
posts. Remove the 5x11 ball bearings from the rockers. Install the same
5x11 ball bearings in the long travel rockers. Secure the long travel
rockers to the pivots with the same 4x6 buttonhead cap screws.
4. Locate push rods
Make sure that all four of the suspension push rods are located
and secured into the middle position (marked LT) on the lower
suspension arms.
5. Reinstall shock absorbers
Reinstall all four shock absorbers back into their respective locations.
GOING BRUSHLESS
Brushless motors provide increased power output and greater
efficiency. The E-Revo is designed with extra transmission and driveline
strength to make it capable of handling extreme brushless power. One
or two brushless motors may be used. A specially designed motor plate
(part # 5690X) and gear cover (part # 5677X) are available for optimized,
single-motor installations. If you plan to run two brushless motors,
ADVANCED TUNING ADJUSTMENTS
be certain that the front motor is wired for reverse rotation. If you
plan to run LiPo battery packs to power a LiPo-compatible brushless
system, see Using LiPo battery Packs in your E-Revo on page 12 for more
information.

MOTOR INSTALLATION

To access the motors, remove the
gear cover by removing the single
screw on the top of the gear cover.
The front motor is held in place
with two motor screws. Simply
remove the two screws to remove
the motor. The rear motor uses
an aluminum mount for quick,
easy motor access and gearing
adjustment. To remove the rear
motor, remove the single large hex
screw using the supplied 3mm wrench. Then rotate the motor and
mount to the side of the model, and slide backward off the post.
The rear motor mount was carefully engineering to provide
additional features and adjustability. Two sets of holes are
provided for use with aftermarket motors. These use 3mm screws
with 25mm spacing that is compatible with most aftermarket
motors. These are:
1. Low CG (center of gravity) installation
(mounts the motor low to the chassis
for best handling performance)
2. High CG installation (mounts motor
higher for more clearance for larger
motors or aftermarket heat sinks)
An additional set of motor mounting
holes is included for custom application.
This is for larger aftermarket motors with
4mm screws and 29 - 30mm spacing.

Use higher viscosity
(thicker) diff oil for:
• More power to the wheels
with the most traction.
• Racing on low-traction
smooth surfaces .
• Better performance for
climbing on uneven terrain.
Using lower viscosity
(thinner) diff oil for:
• More power to the wheels
with least traction.
• Racing on low-traction
rough surfaces.
