Default engine break in vs new clutch break in

New engine...new clutch. CFDF clutch instructions say to drive easy for the first 500 miles. Seating the rings is opposite of that. What does one do in this situation? Thanks for thoughts. Mike

Start out easy, then while the clutch is engaged and in gear, nail it.

It’s not the clutch fiction material that needs to be broken in its only the face of the flywheel so to speak, and even then only if it’s freshly cut.

It’s the same deal as breaking in new pads or shoes where the friction material / lining has compounds in it that under heat get transferred to the Drum or disc as the case maybe which helps the friction lining do it’s job better,

This is also the reason why new pads or shoes never work as good as they could when matted up to a used surface .

I concur. Besides if I screwed up on one or the other I’d rather screw up the clutch than the rings, lol

i thought seating the rings was more about decelerating with engine braking than nailing it to get the rpm’s up. so you could ease up to 5000 rpm or so in second gear going downhill and let it engine brake down to 3000, something like that.

I've been doing it wrong for 40 yrs.
Wether new engine build, clutch, or trans, nail pedal to floor from driveway and from every stop sign. Then out on highway 100 mph sprints.
