NOTE:
Make sure you change or clean your filter after each moto or significant ride. We
recommend carrying three or more filters in your toolbox.
•
1 for practice
•
1 for each moto
CAUTION:
Dusty conditions will require more frequent cleaning.
Frictional Drive (CFD)
The Cobra Frictional Drive (CFD) is essentially a slip clutch that dissipates torque
spikes transmitted from the rear wheel to the rest of the drive line and engine.
Instead of these torque spikes potentially damaging internal components, the
CFD allows the transmission to slip with respect to the engine. For this to occur,
the CFD must function properly by ‘slipping’ between a minimum torque value,
and a maximum torque value.
The slip torque of the CFD should be checked every 5 hours of operation.
Slip Torque
Ft-lb N-m
Minimum 55 75
Maximum 92 125
To properly measure the torque at which the CFD (Cobra Frictional Drive) slips,
one first access the slip clutch by draining the oil and removing the cover
exposing the CFD. Next, brace the CFD gear from turning with a suitable device
(Cobra tool EAMU0004 or similar).
Using a beam style torque wrench, turn the torque wrench counter clockwise and
observe the torque measurement when the shaft slips relative to the gear. Using
a preset value torque wrench, adjust the setting
55 ft-lb (75 Nm)
and observe
whether the wrench clicks first or the shaft slips. If the shaft slips first, the slip
torque is below 55 ft-lb and the CFD needs servicing. If the wrench clicks first,
the CFD is of acceptable value.
