  The shaft driven model is based on a rigid alloy ladder frame chassis, with rear twin axle, gear type differentials, leaf-spring suspension, friction dampers and 3-speed gearbox. A Multi-Function Unit is available separately, to recreate fully controllable light, sound and vibration actions. 9 types of ultra-bright LED lights include headlights, fog lamps and turn signals. 24 types of digitally-recorded sound effects include air-brake, shift change and reverse signal. Vibration unit enables realistic vibrations synchronized with engine sound effects.

  A 540 brushed Motor is included and Plastic bush type bearings, that after a short while, when dust and grit get into them, can actually wear into the metal drive shafts that spin in them - we recommend these should be replaced by a full set of steel shielded ball bearings.

Buying a Used Tamiya Mercedes-Benz Arocs
Tractor Truck (and What to look for)


   There are essentially three reasons you might want to buy a used Tamiya Mercedes-Benz Arocs Electric Tractor Truck; you may be a collector, looking to restore and display it; restore and sell for a profit; or simply restore and race an iconic vintage model. Personally, I used to get a buzz out of restoring an old clapped-out model, installing modern day electrics and maybe a few hop-ups, then showing the gang at our local club, just how competitive those old models could still be.

   Cheap, pre-loved bargain models, parts and spares are always coming up for sale, but once you have made your purchase, the one thing you will always need, is an instruction manual. If not supplied with your purchase, they can often be downloaded from the Tamiya website, or purchased separately on eBay. With an instruction manual, any problems with your model Tractor Truck you may discover, can easily be fixed.

Make a General Visual Inspection

Dampers
   When you receive your used Tamiya Tractor Truck, make a general visual inspection of the chassis, front and rear wishbones, suspension shock towers etc, for any broken parts that may need to be replaced. Then, take a screwdriver and box spanner and check each self tapping screw and nut for security, taking care not to over tighten.

   Next, for those Tamiya models with oil filled shock absorbers, remove them from the chassis and dismantle the coil springs. The damper shafts should push in and pull out with a smooth action. If you feel a jolt as you change direction, this means the oil has leaked out and must be topped up. At the same time, change the O-Ring seals to prevent more leakage. Also check the damper shafts for damage. If they are scratched, change them as soon as possible.

Check the Body-Shell

   If the body shell of your Tamiya Mercedes-Benz Arocs is broken, ripped or damaged in any way, this can be easily repaired with rubber solution glue. Also, for added protection and if available for your Mercedes-Benz Arocs model, fit an under guard to stop dirt and gravel entering the chassis.

Drive Shafts and Turnbuckles

Titanium Turnbuckles
   Examine the drive shafts for wear and replace as required. If possible, change them for titanium. The steel shafts wear and bend too easily.

   If you intend to race your Mercedes-Benz Arocs Tractor Truck model at a competitive level, I would also recommend you obtain and fit titanium pivot shafts, turnbuckles, tie rods and steering rods.

Examine the Drive System

   On Belt driven models, the Drive Belts need checking at regular intervals for wear, tension and damage. If deemed necessary, adjust the tensioning pulley until the belt can be depressed in the centre by no more than around 5mm. If the belt was slack, also examine the drive pulleys for wear. The teeth should provide a well seated fit for the belt teeth and not be rounded on the corners. If the belt teeth do not fit snugly, change the pulleys as soon as possible. For top level racing it may be prudent to replace all belts and pulleys after each race meeting.

   For Gear driven models, the gearbox of your used Tractor Truck should be opened up to check for gear wear and lubrication. A thin coat of grease is often used on internal gears and although this is fine for basic running around on the back yard, if you intend to race your Tractor Truck at a higher level, this should be removed and replaced with racing oil (ZX1 or Teflon Oil). Of course, this should be reapplied after each race meeting.

Pinions and Spur Gears

Spur Gears
   Gears are a weakness on all Tractor Truck RC models. Head on collisions can easily damage the gear teeth on nylon and plastic spur gears. Heavy impacts can also loosen the nuts or self tapping screws that hold the Electric Motor in Position, allowing the pinion gear to pull out of mesh slightly and rip the tops off the teeth on your spur gear. To minimise this possibility, fit bolts with locking nuts to the Electric Motor mount and remember to check them for security after every two or three runs.

Don't Neglect the Ball-Joints

   Ball joints always cause problems. For top level Electric Tractor Truck racing, the plastic ball connectors should be checked and if deemed necessary, changed after every meeting. A simple thing like a loose fitting connector popping off, could easily end your race, so better safe than sorry.

Steering Servo and Servo-Saver

Servo Gears
   The Mercedes-Benz Arocs steering servo is also prone to damage. In high speed crash situations, the fragile gear teeth of the servo can be broken off, rendering your expensive servo useless, so be sure to obtain a good quality "Servo Saver". Check out my Servo Information article.

Stabilizers

   If body roll on your Tamiya Mercedes-Benz Arocs is a problem, handling can be improved with the use of stabilizers, anti roll or sway bars, stiffer tuning springs and, or, thicker silicone oil in the dampers.

Don't Forget those Bearings

Ball Bearings
   If your used Tamiya Tractor Truck comes with plastic and sintered brass bushings (ring type bearings), check the shafts that run in them for wear. Dust and grit can get into these bearings and abrade the shafts. Therefore, you should replace them all with shielded ball bearings. If the model has been run with ring type bearings, you may have to change all the axles and driveshafts. For more information, take a look at my article, How to get the best from your Bearings.

   Finally, good luck with your Mercedes-Benz Arocs model and good racing.

Hints, Tips and Information

Choosing a Transmitter

   When you first started in RC, you may have purchased a package that came with the car kit, motor, battery, charger, ESC and radio system complete. The transmitter was probably just a basic steer wheel, or stick type, with nothing more than forward, reverse, left, right and simple trim settings to centralise the servo and ESC.

   After a while, as your enthusiasm grows and your experience increases, you will want to move on to a better radio system, with more setting options, but where do you begin?

   Choosing the right transmitter is a personal thing. It has to feel right, have the balance you like, not be too bulky for your hand size and have all the features you might need to set up your car to your driving style.

Hints, Tips and Information

Efficient Soldering

   In the sport of Radio Controlled racing, there are a number of things you have to learn to get you up there with the best. One of the most difficult, for those with little practical skill, is the art of Soldering.

   For their 540 silver can motors, Tamiya provide two wires, typically green and yellow, soldered to the endbell, with two bullet connectors to plug into the speed controller. While this is fine for bashing around the back yard, as you advance to a higher level you will soon find just how inefficient this method is.

   Motor wires are best soldered directly to the ESC. That way no energy is lost through high current draw. Some of the top drivers at one time even used to solder their batteries directly to the ESC.
