Tamiya Globe Liner 1/14 Scale Radio Control Tractor Truck

Introduction

This document provides comprehensive assembly instructions for the Tamiya Globe Liner 1/14 Scale Radio Control Tractor Truck model kit. It guides users through the construction process, detailing the use of various parts, tools, and RC components to build a realistic and functional radio-controlled model.

The kit requires separate purchase of radio control equipment (transmitter, receiver, servos, electronic speed controller), a 7.2V Ni-Cd battery pack, and a compatible charger.

Before You Begin

Read Instructions Thoroughly: Study and understand all instructions before starting assembly. Ensure all parts are included and undamaged. Contact your local Tamiya dealer if any parts are missing or damaged.

Liquid Thread Lock: Apply the kit-supplied Liquid Thread Lock only to specified portions during assembly. Do not use other brands, as they may damage plastic components.

Safety Precautions:

• Operate the model in safe, open areas away from children and crowds.
• Never operate the model on public roads.
• Be aware of radio interference. If the model behaves erratically, stop immediately and check for interference.
• Avoid operating in wet conditions. If the RC unit, motor, or battery gets wet, clean and dry them thoroughly in a dry, shaded area.
• Reduce speed before entering corners to prevent rollovers and potential damage.
• Always disconnect the battery when the model is not in use to prevent accidental activation and battery drain.

Operating Procedures:

1. Turn on the transmitter.
2. Turn on the receiver.
3. Check that all controls (steering, throttle, gear shift) are functioning correctly and that servos are in neutral position.
4. After operating, reverse the shutdown sequence (turn off receiver first, then transmitter) and disconnect all batteries.
5. For the first run after assembly, operate the model slowly for approximately 5 minutes, checking the steering and speed controller functions.

Pre-Operation Checks:

• Ensure all screws and nuts, especially grub screws, are securely tightened.
• Verify that transmitter batteries are new and the Ni-Cd running battery is sufficiently charged.
• Adjust the steering servo and trim so the model runs straight when the transmitter controls are neutral.
• Confirm the speed controller is correctly set to neutral. Improper adjustment can lead to runaway models.
• Inspect all wiring for damage, such as exposed wires or breaks.
• Check the motor for unusual noises or excessive heat build-up, which may indicate damage.
• Ensure all moving parts, gears, and bearings are properly lubricated with grease.
• Verify the gear shifting mechanism operates smoothly and correctly. Refer to specific steps for adjustment.

Maintenance After Running:

• Clean off any sand, mud, dirt, or debris from the model.
• Lubricate all moving parts, gears, and bearings with grease.
• Always disconnect and remove the running battery from the model and RC unit after use.

Parts List Overview

The kit contains a wide array of parts, typically organized into bags labeled with letters (e.g., Bag A, Bag B) and often containing specific types of hardware like screws, nuts, or bearings. Key component categories include:

• Body: The main exterior shell of the tractor truck.
• Chassis Frames: The primary structural components (left and right frames).
• Hardware Bags (A-F, etc.): Contain various screws (tapping screws, round screws, step screws), nuts (standard, lock nuts, flange nuts), washers, E-rings, ball connectors, and pins.
• Gear Sets: Include various gears (pinions, mission gears, bevel gears, ring gears) and gear shafts necessary for the transmission and differentials.
• Bearings: Metal bearings (BM1, BM2) are used in rotating assemblies for smooth operation.
• Dampers: Components for the suspension system, including shafts, springs, and cylinders.
• Drive Components: Differentials, drive shafts, propeller shafts, and axles connect the drivetrain.
• RC System Components: While not included in the kit, the manual details the installation of a receiver, servos, and electronic speed controller (FET amplifier).
• Cab Interior: Includes parts for seats, dashboard, steering wheel, and control levers.
• Exterior Details: Parts for windows, mirrors, lamps, exhaust system, fuel tanks, front grille, mud flaps, and bumpers.
• Stickers: Decals are provided for detailing and applying markings like license plates and logos.

Diagrams throughout the manual illustrate the specific parts and hardware required for each assembly step.

Assembly Instructions

The manual provides detailed, step-by-step instructions for assembling the Tamiya Globe Liner. Each step is accompanied by diagrams showing the parts and hardware to be used.

Chassis and Drivetrain Assembly

Early steps focus on assembling the main chassis frame, installing suspension components (leaf springs, dampers), and mounting the steering and shift servos. The differential, rear axle, and gearbox assemblies are constructed, followed by the installation of the motor and drivetrain components like propeller shafts and drive shafts.

Cab and Body Construction

Later stages involve assembling the truck cab, including the interior details such as seats, dashboard, and steering wheel. The cab is then attached to the chassis. Exterior components like windows, mirrors, lamps, fuel tanks, and the front grille are installed. The manual guides the application of stickers for detailing and marking.

Final Touches and Operation

The final steps cover attaching the exhaust system, mud flaps, and bumpers. The manual also includes instructions on connecting the RC system components (receiver, servos, ESC) and adjusting the steering and gear shift mechanisms for proper operation. Maintenance guidelines are also provided.

Key Assembly Actions Depicted in Diagrams:

• Attaching chassis cross members and suspension plates using screws and nuts.
• Mounting steering and shift servos to the chassis.
• Assembling differential gears with bevel gears, shafts, and bearings.
• Connecting drive shafts and axles to the differentials and hubs.
• Installing leaf springs and dampers to the chassis and suspension arms.
• Assembling and mounting the gearbox and motor.
• Connecting propeller shafts to the transmission and axles.
• Assembling the truck cab interior, including seats and dashboard.
• Attaching windows, mirrors, and lamps to the cab.
• Mounting the cab onto the chassis.
• Installing fuel tanks, exhaust pipes, and mud flaps.
• Connecting RC system wiring (receiver, ESC, servos, motor).
• Adjusting steering linkage and gear shift servo linkage.
• Attaching wheels and tires to the hubs.
• Applying stickers for detailing and markings.
