NN Assembly Instructions

Included Parts:

Top Link Mount Assembly

The motors can be installed at this time or any time before the axles are attached to the chassis.  It is easier to install the motors before the axles are attached to the chassis.  Assemble the top link mount on both axles.  First remove the stock screw and nut shown below.

Next insert the 4X30 cap head screw with M4 washer into the bottom of the top link mount hole then insert the 22mm spacer from the top.

Next install the nylon post and tighten the 4X30 screw from the bottom.

Then install the 3X35mm screw, washer, and nut as shown and tighten.  Repeat this for the other axle.

Save the shown hardware in a zip lock bag for use later.  (The 3x30mm screw and nylock nuts shown are now in screw bag C and D and not bagged with the upper link mount).

RX-ESC Plate

Install the RX-ESC plate on the short axle tube brace as shown.  The plate can be installed on the front or rear axle.  Use the 3x10mm screws in bag C.

Servo Installation

Next install the servo on the front axle.  Use the included servo stand-offs and hardware to install the components as shown.  Use the two countersunk screws to mount the posts to the axle tube brace.  When installing the servo mounts, leave the screws that go through the axle tube brace loose.  You will tighten them up later.

Use the hardware shown to attach the servo to the servo mounts.  Install the servo and tighten the servo mounting bolts while squeezing the posts together. 

Then, after the servo is secured to the posts, tighten the servo posts from under the axle tube brace.  You will install the steering links after the axles are mounted to the chassis.

The hardware shown is not used:

Chassis Assembly

Remove the skid plate, side plates and 4ea chassis separators (small parts bag) from their bags.  Use the 3x8mm (Bag A) button head screws and nylock nuts to loosely attach the side plates to the skid plate as shown.  Do not tighten any of the hardware.  If the screws do not push through the holes easily, turn them into the hole as if they were threaded.  The holes that the screws are inserted into in the pictures are used for the 14-16" wheelbase configuration.  If you will be setting up a 17" wheelbase mount these screws one hole location closer to the center. 

Install one chassis separator per side in the bottom hole location with the 3x8mm button head screws.  Use locktight to secure these screws from loosening.  Leave all hardware loose. 

Then install the upper chassis spacers with the hardware shown (3 X 25mm cap head screws (bag B) and 8 X 10 aluminum spacers(bag A)). 

Now tighten the lower chassis separators and then the chassis bolts (side plate to skid plate screws).  Do not tighten the upper chassis spacers(3x25mm screws).

Link Assembly

The following parts may be included with some kits and are not used:

Insert the ball into the socket as shown using a pair of pliers:

Now, install the set screw (bag F) into the rod end as shown.  Only screw the set screw into the rod end half way as shown.  Make sure the set screw is straight while tightening.

Make 4 links by screwing the ball ends into the threaded rods as shown. 

**Some links are clear anodized and may have some material on the link threads that make it difficult to thread the rod end/set screw into the link.  If this happens, apply some light oil to the set screw and then screw the rod end/set screw into the link.  If you are still having difficulty with the threads, use one of the 3mm hex head screws with some oil.  If the screw will not thread in very far, remove the screw and apply more oil.  Repeat until you have cleared enough of the threads for the rod end/set screw.**

For the last 4 links, screw in one rod end per threaded rod.  Then install two collars per link (small parts bag).  You may have to loosen the set screw in the collar for the collar to slide onto the link/threaded rod.  Then install the other rod end to complete the link assembly. 

The 4 shorter button head screws (3 X 12mm- Bag B) are used to attach the upper links to the chassis.  The 4 longer screws (3 X 14mm- Bag C) are used to attach the links with the collars to the bottom holes in the chassis.  Attach the links as shown (16 inch wheelbase - recommended).

Attach axles to chassis

Insert the brass tube into the top link mount.  Then use the 3X30mm (Bag C)  screw to attach the upper links to the top link mount. 

Next attach the lower links as shown using the 3X16mm screws (Bag B).  The holes in the axle tube brace may have to be drilled out if they are threaded.  Drill the axle tube brace hole just large than the 3mm screw so the screw can pass though the axle tube brace.

Shock Installation

Use the hardware shown to install the shocks as pictured.  Use locktight on the upper shock mount bolts.  You adjust the ride height of the truck by adjusting the position of the lower shock mount along the link.  Closer to the axle will give a lower ride height.  The lower shock mounts are installed using Traxxas shoulder screws 3X12X5mm, Traxxas part number 3642, 4ea fender washers (Bag E), and 4ea nylock nuts (Bag D).

Steering Links

It's common practice to cut the small nubs on the steering knuckles off to increase your steering radius.  You will want to do this at this point before you install the knuckles.  You can use a dremel or a pair of wire cutters.  Next, re-install the knuckle arms. 

Use the remaining rod ends with set screws installed to complete the steering links.  Then install the front and rear steering links as shown.  Attach one end of the short link to your servo saver with the 3x16mm screw, one locknut as a spacer, a fender washer and then one locknut on the backside.  Then attach the long link on the under side of the knuckle with the short steering link on top.  Use a fender washer as shown and a 3x25mm screw for the left knuckle (shown on the left in this photo).  Then attach the right side knuckle to the long link using a 3x16mm cap head screw, one fender washer and one nylock nut as shown.

Install your electronics and body posts (not included) as shown.  Use Velcro or servo tape to attach the electronic speed control and receiver.  Use Velcro to attach the battery.
