Wheel Changing

The safety of young drivers is very important to us. That is why, for many years now, to assemble the wheels we have been using so-called “cap studs”, i.e. rivets with integrated metal claws that, once struck, connect securely to the axles, thereby preventing the wheel from falling off.

New caps plus a metal hammering tool and plastic sleeves are included with each set of spare wheels from BIG. Instructions on how to change a wheel can be found in the right-hand info box.

To disassemble the caps insert a plastic sleeve in the metal hammering tool and position this on the cap being removed. Strike the metal hammering tool firmly with a hammer until the claws of the cap disengage. Remove the cap with the aid of a flathead screwdriver. You can then remove the wheel.

We recommend that experienced craftspeople use a drill with an 8-mm bit to disassemble the caps. Drill open the top of the cap or the side notches. This will take away the tension, allowing the cap to be easily removed with a pair of pliers.

To assemble the wheels of all BIG BOBBY CARs, please strip down the relevant axle and attach a wheel. Fit this to the axle by striking the cap firmly until it holds the axle evenly and securely. Then insert the axle again and attach the second wheel.

Please finally check again, for the young drivers’ safety, that all the caps are evenly and securely fixed to the axles and hold these firmly to prevent the wheels from coming loose!

Attaching Decals

To guarantee good retention of the decals on your BIG vehicle, we recommend you clean it with a conventional detergent before attaching the decals, in order to remove any grease residue. Then use a hair dryer to blow-dry the vehicle surfaces that are to be covered and attach the decals.

Drive Chain Tensioning

Should the chain on your BIG Tractor lose tension, you can increase this again easily with a few simple hand movements.

To do this, remove the cover of the chain box or the imitation engine block. The drive chain and the pedal discs should now be visible. Loosen the two disc screws and turn the disc in the direction of the seat, until the drive chain is sufficiently tensioned again. Ensure that the discs are in the same position on both sides of the vehicle. Then replace the cover or the engine block and screw it in place.

You can find illustrated instructions in the following file. Please ensure that only adults are responsible for tensioning the chain.

Fitting Running Rings

The wheels of some BIG vehicles are fitted with running rings for good grip and quiet driving. Nevertheless, these may come loose after numerous journeys, so that a retrofit with new running rings is advisable.

Before fitting the running rings, they must first be made pliable so that they will subsequently grip firmly on the wheels. To achieve this, place the running rings in a very hot water bath for approx. 10 minutes. The temperature should be at least 70 - 80 degrees. Remove the running rings and pull these over the wheels.
