Now set your 3rd channel endpoints. Make sure that when the servo is at the 4wd and dig position that the unit is in its respective gear but not causing the servo to bind, this is accomplished by setting your 3rd channel endpoints. Failure to do so will cause premature servo failure, battery drain and in the 4wd position will cause abnormal wear on the shift fork and dig out drive groove and loss of power due to added friction. Rule of thumb is if the unit is fully in gear and the servo is still making an audible noise then you need to back off on that endpoint. You will find that moving the servos neutral position or trim will also cause the unit to disengage from 4wd and dig differently and a little tweaking in this area can typically make the unit perform as desired. If you do not have end point adjustments on your 3rd channel it is highly recommended that you use a servo stretcher with end point adjustments CLICK HERE to see an example. Otherwise you will need to spend some additional time setting up your link edge so it will not bind the servo. If you do indeed go against our recommendations and choose to let the servo bind make sure it only binds in the dig position and not in 4wd as the dig unit will prematurely wear.
You will now need to reverse your motor direction. Brushless users can accomplish this by reversing 2 of the 3 wires going to the motor. Brushed users will need to reverse the polarity of both wires going to the motor via reversing the wires at the motor itself or at the plug attached to the motor is so equipped.
Reattach transmission/motor to motor plate using existing screws. Install skid plate in the opposite direction as removed (dig system facing rear axle). Reattach lower links with existing hardware. Reattach motor wiring and plug in the dig servo to the desired channel. Install front driveshaft and tighten yoke set screws (Locktite recommended at this location).
The upper link bolt on the dig side may need trimming or use of a shorter length bolt depending on hardware used during assembly (indicated below).
Now you will need to trim 3/8 to 1/2 in of material from each half of your rear drive shaft depending on which upper and lower link mount locations you are using. Basically your driveshaft will need to be short enough in the rear that you can put your dig unit in dig mode and compress your suspension fully without the driveshaft trying to push in on the dig unit. Special care must also be taken to make sure that the two drive shaft halves slide in and out from each other smoothly and easily, failure to do so may cause the dig unit bind due to the fact that the dig output shaft moves in and out during normal operation and needs the drive shaft to do so as well.
Install your rear driveshaft and tighten the yoke set screws (Locktite recommended at this location).
Last and most important step GO DIG IT !
