Complete conical Front sprocket bell 72 Crimaz

Attention: only compatible with straight-tooth bells.

Innovative Crimaz conical crankshaft pinion system, thus eliminating the need to fit the key.

Ideal for tuned engines, and it is even the perfect solution when the crankshaft keyway is in poor condition.

We recommend tightening the nut with a torque wrench to the torque specified by the manufacturer of 70NM (7kg), and for extra security apply threadlocker to the nut.

Assembly: fit the cone onto the crankshaft, place the pinion, apply threadlocker to the thread and fit the washer and nut, lock the pinion with that of the

bell with a tool to tighten it to 70NM (7Kg). If you do not have the tool, a 5 cent coin will suffice.

Disassembly: position the extractor over the pinion, screw in the three bolts, once assembled tighten the central bolt which presses against the crankshaft until

remove it.

Straight-tooth pinions available.
