Center Differential Instructions
Tools needed: 2.5mm hex driver
Covers Part #6780
Center Differential Installation:
1. Locate and remove the button-head cap screws from
the top rear of the chassis (2) and from the bottom of
the rear skid plate (2) with a 2.5mm hex driver.
2. Remove the modular rear end from the chassis by
sliding it backward away from the chassis. This is to
access the spur gear/slipper unit.
3. Remove the spur gear/slipper unit from the rear of the chassis.
4. Insert the center differential unit into the rear of the chassis (where the spur gear/
slipper unit was removed).
5. Attach the rear end unit to the chassis, keying in the rear output shaft of the center
differential with the opening in the rear differential. Secure the assembly with the
same four button-head cap screws.
Tip: Rotate the rear wheels
slowly while attaching the rear
end to the chassis to properly
set the rear output shaft of the
center differential into the rear
differential. You should feel the
rear end set into place (A). The
rear skid plate should lock into
the bottom of the chassis (B).
Rotate the rear wheels slowly until
the output shaft keys into place.
BA
Lock the rear skid
into the chassis.

Center differential tuning:
The center differential is assembled with 1M weight differential lube from the factory.
This viscosity will be a good base point for most conditions. Thinner fluid will transfer
power easier than thicker fluid. Try thinner fluid on extremely rough and slick surfaces,
and thicker fluid on very smooth and high-bite surfaces.
