Adjusting Gear Mesh
Incorrect gear mesh is the most
common cause of stripped spur
gears. Gear mesh should be
checked and adjusted anytime
a gear is replaced. To set the
gear mesh, cut a narrow strip
of notebook paper and run it
into the gear mesh. Loosen
the motor screws and slide the
motor and pinion gear into the
spur gear. Retighten the motor
screws and then remove the
strip of paper. You should be
able to run a fresh strip of paper
through the gears without binding them.

Tuning the Sealed Differential
The differential is sealed to maintain consistent long-term performance. Changing the oil in the differential with either lower or higher viscosity oil will
vary the performance characteristics of the differential. From the factory, the differential is filled with black lithium grease, but can also be tuned with
silicone differential oil. Only use silicone oil in the differential. The differential has to be removed from the transmission and disassembled to change/
replace the oil.
Follow the steps below to access and refill the sealed differential:
1. Remove the four 2.5x10mm cap screws from the bottom of the transmission to remove the differential cover.
2. Slide the differential out of the transmission case.
3. Remove the 2.5x10mm button-head cap screws from the differential and carefully pull the differential halves apart.
Work over a towel to collect any fluid that drips from the differential.
4. Drain the fluid from the
differential. You may wish to
remove the spider gears from the
differential to make this easier.
5. Place the spider gears back into
the differential carrier (if you
removed them). Fill the carrier
with fluid until the cross pins
are covered.
6. Rejoin the differential halves,
using care to align the screw
holes. Be sure the rubber gasket
is in place or the differential
may leak.
7. Install the 2.5x10mm button-head
cap screws and tighten securely.
8. To reinstall the differential, reverse
the steps.
