Mechanical configuration of linkages

 
PURPOSE
A mechanical configuration of linkages is to move the clutch lever fork.  A mechanical configuration is used instead of a hydraulic clutch applicator.  This is also adjustable.  A mechanical configuration may also use a cable that makes it adjustable.  Any clutch assembly must have free play.

THINGS TO LOOK FOR
A mechanical clutch configuration may require adjustment.  If you notice the pedal becoming hard to press this could be an indication of a frayed cable or a clutch assembly sticking.  As the pedal becomes harder to push this shows that it needs to be attended to ASAP.  A mechanical or cable clutch assembly may not tolerate a hard pedal and either snap the clip or rod.  When driving up hill if you notice the engine revs increasing but the speed doesn’t, the clutch assembly is slipping.  It either requires adjustment or the assembly itself needs replacing. 

IS IT EXPENSIVE TO REPAIR?
Most mechanical configurations use a cable assembly which costs between $60.00-$80.00 for the cable.

TEMPORARY REPAIR AND LONG TERM REPLACEMENT
A cable or mechanical assembly is best with 2-4mm free play.  A cable without free play will cause the clutch assembly to slip and rapidly deteriorate costing a lot more than the cable or cable adjustment.
