 Section 1

LiteHawk OVERDRIVE 4X4 MT Body Removal:

  Remove all 4  body clips from the body mount, and lift the OVERDRIVE body off.

                                 

Section 2

 LiteHawk OVERDRIVE 4X4 MT Battery Charging:

  With the body removed from the Truck, you will see the battery compartment with the battery connector and the ESC/Receiver connector sticking out.

                                  

To remove the Battery Cover, squeeze the two sides inwards and lift the cover straight up and off.

       

Before you take that cover off, take a really good look at how the battery connector and wire is fed out of the battery compartment for hooking up outside of the compartment.

                                  

Now lift off the cover and note the position of the Battery for later installment.

                                  

 

  You should charge your battery before first use and after using the battery, let the battery cool off for 10 minutes and then fully charge it before storing.

  When you plug your battery charger into a power source, the LED light on the charger will be green. 

                                  

  When you plug your battery into the charger, the LED light will turn red, and will remain that way until it is fully charged. Charging should take between  2.5-3 hrs.

                                   

  When the battery is fully charged, the LED light will turn back to green.

                                  

Do not leave on charge overnight. Battery should be unplugged from the charger after a maximum 8 hours.
Unplug the battery from the charger and remove the charger from the wall plug. Install battery into your vehicle, only when you  are ready to make a run with the OVERDRIVE.

During charging:
- It is normal for the battery to get warm during the charging process. Do not charge the battery on a surface that is flammable or can be damaged by heat. 
- Do not leave the battery and charger unattended while charging.
- Do not store the battery plugged into the charger or plugged into your truck.    

 

Section 3

 LiteHawk OVERDRIVE 4X4 MT  Syncronization:

  First turn on your Radio/Transmitter, a red power light will come on blinking.

                                 

Now plug in your trucks battery, and turn on the start switch on the ESC/Receiver. The red LED light at the ESC should come on Solid and at the same time the blinking red light on the Radio should go solid, and the Radio's Blue lights will come on as well, indicating that they are bound, and ready to roll! Just put the Body back on!

                                  

If the lights on the truck and Radio remain blinking, they have not bound. Turn them both off, and repeat the procedure.

 Section 4

LiteHawk OVERDRIVE 4X4 MT Wheel Removal:

  Your OVERDRIVE comes with a 7mm metal wheel wrench to remove the steel Ny-Loc Wheel Nuts. The Nuts are made with a nylon inset that locks the wheel to Axle.

        

  When removing the wheel, be aware that there is a Wheel Hex nut holding an Axle pin in place, just underneath. Be careful that you don't lose the pin.

       

Section 5

 LiteHawk OVERDRIVE 4X4 MT  Front Shock Removal:

  The Front Shocks are attached at the top to the Shock Tower, and to a Ball and Socket with a Retainer Screw on the Lower Front Control Arm.  Remove the two screws. Then grasp the Shock as close to the ball and Socket on the Lower Control Arm as you can, and Lever it off carefully. Press and snap fit to put back on.

       

Section 6

 LiteHawk OVERDRIVE 4X4 MT Rear Shock Removal:

   The Rear Shocks are attached at the top to the Shock Tower, and to a Ball and Socket with no Retainer Screw on the Lower Rear Control Arm, just the Ball and Socket.  Remove the single screw. Then grasp the Shock as close to the ball and Socket on the Lower Control Arm as you can, and Lever it off carefully. Press and snap fit to put back on.

       

Section 7

 LiteHawk OVERDRIVE 4X4 MT Front Upper and Lower Control Arm, and Front Steering Hub Removal:

   To be able to get to the Upper and Lower Control Arm Hinge Pins, you first have to remove the Front Bumper. Take out the two screws from the bottom of the Front Chassis that secure the Bumper. 

                                    

   Now you can get to the Hinge pins. TIP.. These Screws are secured in the Toe Blocks very very tight. Don't strip the screw heads. If it is too tight, get a pair of Vice Grips that will grab the round head of the Hinge and attach firmly, then gently twist until loose. Then remove the Grips and finish with your screw driver.

                                   

   With the Hinge Pin removed, and the Axle Pin out. The Universal Drive shaft/Axle will literally fall out.

                                   

   You need to remove the Retaining Screw from the Ball and Socket joint on the Front Steering Hub, the grasp the Control Arm as close to the ball and socket as you can and carefully lever it off.

       

   Now you can remove that Hinge Pin from the Lower Control Arm.

       

   To remove the Lower Control Arm from the Steering Hub, turn the truck over  and remove the retaining screw from the ball and socket joint, then carefully lever the Control Arm off.

       

   To remove the Steering Hub from the Steering Tie Rod just remove the screw. It will now slip off.

       

  To remove the Wheel Bearings, just slip a small straight screw driver through the Hub and carefully push on the back of the bearing, it will pop out. Turn the Hub over and repeat for the second bearing.

              Carefully reassemble in Reverse order.

Section 8

  LiteHawk OVERDRIVE 4X4 MT  Rear Upper and Lower Control Arms, and Rear Wheel Hub removal:

  You do not need to remove the Rear Bumper to remove the Rear Control Arms, I have done so for ease of photographs.

  So to begin, here are the 4 screws that you need to remove to take off the Rear Bumper.

         

  Remove the Rear Upper Control Arm Hinge Pin. When you do the Dog Bone/Rear Axle will fall out. If the Axle pin is removed, you can slide out the Rear Axle. 

                                  

  To Remove the Rear Upper Control Arm from the Rear Wheel Hub, you need to press out the Knurled pin that holds it in place.

       

   To Remove the Rear Lower Control Arm, remove the Rear Lower Control Arm Hinge Pin. Then Press the Knurled pin that holds the Wheel Hub in place.. out, and set the Wheel Hub aside.

       

    To remove the Wheel Bearings from the Rear Wheel Hub, just slip a small straight screw driver through the Hub and carefully push on the back of the bearing, it will pop out. Turn the Hub over and repeat for the second bearing.

       

  Carefully Reassemble in Reverse Order.

 Section 9

LiteHawk OVERDRIVE 4X4 MT Battery Box Removal:

  Tip: To get to the Steering Servo compartment or the ESC/Receiver/Motor Compartment, you will need to remove the Battery Box. If you need only the Front Diff. you don't need to remove the Battery Box.

  To remove the Battery Box, take out the Six screws holding it in place.

                                   

  Before you lift the battery box out, check how the battery hook up wiring, to the ESC is placed between the battery box and the servo cover, for reassembly later.

       

  With the battery box out, you can see and disconnect the Servo if you need to, and remove which ever cover you need to work on, front or rear.

                                  

 Section 10

  LiteHawk OVERDRIVE 4X4 MT accessing the Front Differential and Steering Servo and Steering Horn Assembly with Steering Tie Rods:

     To remove the Servo/Front Diff. Cover, remove these eight screws.

       

   Now carefully lift off, and set the cover aside. You can see how the Differential is set to the Left hand side in this picture.. for reassembly later.

                                  

   To Remove the Servo Unit. Disconnect the 5 Wire Servo connection to the ESC. Take out the screw holding the Servo Horn in place. Then remove the two screws holding the Retainer in place.  Separate the retainer and horn from the Servo Unit, and lift the Servo Unit out.

         

     Now you can remove the Servo Horn Assembly and Steering Tie Rods. Take careful note the orientation of the Horn linkage at the Servo Unit before you remove it, and not that it is sitting at a perfect 90 degrees with the Wheels pointing straight ahead. That is how you want to hook it back up on reassembly.

                                  

   Turn the Chassis over and remove the four screws from the Steel Skid Plate Toe Block Mount, and set aside.

                                  

Lift the Horn Assembly off of the Bearing, being careful that you don't lose that bearing, slide the first half of the small steering link out of the hole in the bottom of the Chassis. Then grasp the ball and socket connection between the small steering link and the large Horn Assembly as close to the ball and socket as you can and lever apart. Now you can remove the two pieces from the Chassis. To remove the steering tie rods just remove the screws holding them to the Horn Chassis. It is possible to maneuver the short steering links through the small hole in the chassis without taking them apart, but it can be difficult.

                                 

    

   Carefully Reassemble in Reverse Order.

 Section 11

LiteHawk OVERDRIVE 4X4 MT accessing the Rear Differential, ESC/Receiver, Dual Drive Motors and Main Drive Shaft:

   With the Battery box already removed and the Servo harness disconnected. Start with removing the Six screws that hold down the Cover for the Rear Diff. and Motors.

                                 

   Now very carefully, separate and lift off the Rear Cover, being aware that the Motors are housed in the Cover of the Rear Chassis with the ESC. This is because the motors are soldered to the ESC.

                                 

   Here is a picture of the whole chassis with both covers off, which you would need to do if you had to replace your main Drive Shaft. You will need to remove the Servo Unit to remove the Drive shaft.

                                  

   Take Note for reassembly: Orientation of Locating Knobs on Motor Mounts for bottom of Chassis.

                                 

   

    Now remove the Motors from their Cradle, and lay them outside of the assembly.

                                 

    Take a look at the Snap Clips from the ESC just poking through on the Cover.

        

   Pick one or the other Snap Clips, and take a medium flat head screw driver, and poke it inward and down, to just get it loose on the other side. Now turn the whole package over. Using the flat head screw driver, slip it under the edge that you have created between the Cover and the ESC, and twist the screwdriver so that pressure spreads the  wall of the Cover away from the Wall of the ESC , and the ESC should slip free.

        

    To Remove the Motor Mounts, there are two screws in the front that you need to remove. 

                                 

   If you are replacing Motors or the ESC, you will have to remove the motors by Desoldering them from the ESC.  Carefully Reassemble in Reverse Order. Take notice for Reassembly, Orientation of Locating Knobs on the Motor Mount when the Motor is inserted into its Cradle in the rear Chassis Lid.

                                 

  Carefully Reassemble in Reverse Order. Good Luck. : )
