I had my dealership install a whole new clutch (pressure plate, disk, throw-out-bearing, etc.) and I asked my service advisor and they had no clue

Anyone know if a break-in period is necessary? I've been driving 50 miles since I had the OEM clutch replaced with a new one for 50 miles now staying under 4k rpms. Thanks.

It's broken in after fifty miles.

was told long time ago that it was 500 miles and no high revs.. but been working on cars since than.. and its not really needed..

There are multiple friction surfaces that must seat. It is prudent to perform a good number of engagements before putting heavy loads... it depends upon the number of standing starts and shifts but I always take it easy for the first 400 miles.

Thanks guys, I'm glad I didn't push it hard yet, I'm gonna put another 350 miles and make sure its properly broken-in.

Don't just drive the 350 miles
IMO you'll have to do some easy standing starts & shifts to get the parts to seat properly.

Much like the seating of brake rotors & pads, increase load gently.

In about 10 days I'll have my Comptech & ACT to break-in.

Some say 50 miles, some say 400, 500, 10 days... I'm

Why so many conflicting answers?

Because it is number of engagements that count, not number of miles. I guess we can say just count to 2500 to 3000 uses of the clutch but that is hard to track.

Amer

Wow so basically 2500-3000 times of shifting? I guess its safe to assume 400-500 miles of daily driving.

Amer

anyone else have any ideas? so far I'm at 300 miles break-in and shifting at 4500 rpms.
