The history and usefulness of the product (track side)

On a 125cc karting gearing motor, the crankshaft pinion is the very first centerpiece that transmits the kinetic energy of the low engine towards the rest of the transmission. An original sprocket at the exact odds (Z18) guarantees fluid operation, limits the yield losses and ensures the reliability of your mechanical set in intense race condition.

The mounting tuto (step by step)

To replace your crankshaft pinion in the rules of the art:

• Disassembly: Remove the clutch housing and extract the old used crankshaft gear with the adapted extractors.

• Cleaning: Degrow and clean the conical or cylindrical range of the crankshaft to remove any trace of impurity.

• Setting up: Position the new Z18 TM R3 pinion by keeping up with the original keys and stalls.

• Tightening: Tighten the crankshaft nut to the torque prescribed by the manufacturer using an appropriate engine lock tool.

Michel's Tip (Paddock Expert Council)

"Never attempt to mount a R3 Z18 pinion on an old K9 or R2 motor low by thinking that this adapts: the modules and alignments are specific to each generation. Always observe the manufacturer assignments to avoid exploding your gnaton from the first track tours! "
