21 00 ... Breaking In SAC Clutch

21 00 ... Breaking in SAC Clutch


Break in SAC clutches moderately to ensure correct operation.

Caution!
Fast sports driving maneuvers destroy new clutches!
Such maneuvers include:
Driving maneuvers with high speed differentials
Overlapping gearshifts with high speed differentials (slipping clutch)
Very high starting speeds (e.g. when driving onto a transporter)

Comply with the following procedure when breaking in the new clutch:
- Break in friction linings with light to medium loads (observe breaking-in program)
- Normal driving with many �moderate� gearshifts
- Starting speeds on the level up to approx. 2000 rpm
- Specific breaking-in program on gentle gradients
- Starting speeds on a medium gradient up to approx. 2500 rpm (e.g. when driving onto a transporter)

This procedure helps to create a carbon layer between lining and metal friction surface which generates the required coefficient of friction.





Note: Experience shows that approx. 800 to 1000 gearshifts are required for an optimally broken-in lining when a car is driven �normally� (advise customer).
