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.
Breaking-in program:
•
At approx. 30 km on roads
(specially for M5 and Z8)
•
Shift through gears often
Starting speed max. 2000 rpm
•
Upshifts
1>2>3>4>5
•
Downshifts at 2000 rpm
5>4>3>2>1
•
Upshifts and downshifts
at 3500-4000 rpm
•
3 to 5 times starting on gentle gradient (up to
approx.
12 %)
Starting speed max. 2500 rpm
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).
