3.2.4 Driving mechanism
Chain
The go-kart has a driving mechanism with two chains. Make sure that the chains are sufficiently oiled
so that they can run freely. If a chain is too tightly tensioned, the go-kart will be more difficult to pedal
and there is a big chance that wear and tear of the chains and sprocket, among other things, will occur
faster. If a chain is not tight enough, then the chain can easily come off the sprocket, or there is a chance
of damage to the chain housing. When both chains must be tensioned, always begin with the rear/short
chain.
To tension the rear chain:
• Remove the protective hood.
• Loosen the nuts of the hub.
• Tension the chain by moving the hub forwards.
• Make sure that the hub remains exactly parallel to the rear axle.
• Tighten the hub nuts again.
• Tighten the hub nuts again and place the black plastic cap back in its original position.
• The chain has the correct tension if the middle can be pushed 6 millimeters downwards.
• Tighten the four bolts again. Keep the sprocket wheel parallel to the chain guard.
• Mount the chain guard when the chain has the correct tension.
• The chain guard has to be removed to grease the chain and check the chain tension.
