From page 106 of the Owner's Manual:I just had a new LUK clutch and flywheel put in, other than clutch drops and burnouts, there really doesnt seem to be much for a breakin.
Its smooth as butter and pulls so nice.
The shop did a couple of 7K rpm clutch drops so I'm good :thumbsup:From page 106 of the Owner's Manual:
The clutch will also begin to function
optimally after about 300 miles
(500 km). Engage the gears carefully
during the break-in period.
i'm at 145 changes today (can't believe i'm actually counting this stuff) :noSMG:Break in SAC clutches moderately to ensure correct operation.
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
This procedure helps to create a carbon layer between lining and metal friction surface which
generates the required coefficient of friction.
• At approx. 30 km on roads
(specially for M5
• Shift through gears often Starting speed max.
• 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
Starting speed max.
Note:broken-in lining when a car is driven "normally" (advise customer).
Experience shows that approx. 800 to 1000 gearshifts are required for an optimally
I think the "book" on a clutch install is somewhere between 8-10 hours. Your dealer can give you a quote.^ oh the joys of living in FL.. so how hard/ how much should labor cost on an install? im looking to doing a new clutch soon, I'm thinking of getting a ltw fly wheel but i had one on my last M3 and i hated the chatter noise at lights and stuff.. anybody know if a LTW fly wheel and LUK clutch go hand in hand?
