The assembly process focuses on building a gearbox purely for mechanical detail or manual turret operation, along with the installation of a manual switch plate. It is broken down into five distinct steps that guide the builder from internal gear assembly to the final wiring of the switch.
The assembly begins with the internal mechanics of the gearbox housing. The first step requires inserting the main drive shaft, referred to as the gear shaft, down through the top of the gearbox. A small A13 cap is placed on top of this shaft, and a spur gear A is fitted onto the bottom, secured by a larger A14 bag cap. Moving to the second step, the internal gear train is assembled. This involves placing spur gear B onto the upper section of the gear shaft, while another spur gear A is mounted on a separate vertical shaft running parallel to it. The diagram clearly shows how these gears mesh together inside the casing, creating the internal mechanism.
The third and fourth steps bridge the gap between the internal gearbox and the external motor mount, even though this is the static version. The instructions show how to assemble a D3 motor assembly, but in the context of the non-motorized tank, this space is likely just capped or used as a mounting point. The fourth step specifically highlights the attachment of a pinion gear to a motor shaft by tapping it into place, and notes a unique mechanical detail: the motor should be mounted by pressing it into position, and then the end of a metal claw must be bent to secure it.
The final and most complex step, step five, involves installing the electrical control system into the lower hull of the tank. This is a fully manual switching setup. The builder must prepare a C20 switch plate board, using a 2.6mm tapping screw to attach a switch plate and a load wire for the motor. Specific instructions are given to bend the contact points and claws outward to ensure proper mechanical contact. Once prepared, this switch plate assembly is mounted inside the tank chassis. The wiring is then routed: a blue wire connects to the left side, and a red motor lead wire connects to the right side. The entire assembly is secured to the hull floor using 3mm screws, and a small D6 plate lip is fitted into place to complete the internal mechanical and electrical setup, finishing the construction of the static tank’s interior.
