Clutch Break-In Procedure
All McLeod street performance clutches require a Break-In Period of 500-750 miles of street, stop and go type of driving prior to driving at wide open throttle. This mileage is required to properly seat the disc with the pressure plate and the flywheel. The mileage listed will provide about 1200 apply and release cycles to the clutch assembly.
DO NOT run the vehicle on a chassis dyno prior to full Break-In procedure.
Important: During performance driving and break-in, all traction control devices must be turned off or clutch slippage will occur!

1/4” = 15 FT. LBS
5/16” = 25 FT. LBS
3/8” = 35 FT. LBS
7/16” = 65 FT. LBS
½” = 70 FT. LBS
8MM = 25 FT. LBS
10MM = 45 FT. LBS
10MM Crank Bolt = 65 FT. LBS
11MM Crank Bolt = 65 FT. LBS
1. Change the pilot bearing.
2. Break the clutch in according to the instructions provided.
3. Ensure proper bellhousing alignment.
4. Resurface the flywheel. This is a critical step to guard against clutch chatter/shudder. We recommend a very coarse surface texture from a stone grinder. Something that if you ran your finger nail across the flywheel, the texture would catch your nail.
5. Inspect the entire clutch system including hydraulics and linkage. Replacement of the Hydraulic slave with an OEM replacement is critical.

- A Single disc application is installed with the completely flat side facing the flywheel. The protruding side of the hub (side with springs) assembly will face up towards the pressure plate ( in most cases)
- A Double disc unit will have both hubs with the protruding side of the hub face up towards pressure plate and towards the transmission. (in most cases)
Yes. The pins help to ensure proper alignment of the pressure plate and add strength.
The biggest factors in clutch life are the way it is used and the output of the engine. McLeod Clutches are designed for maximum life but that life can be shortened by using much stickier tires than stock, stop and go driving, track use, tires of larger diameter and other factors that place added stress on the clutch.
We would like to see 500-750 miles of stop & go city driving. With no drag racing or dyno tuning. Make sure to drive in stop & go city driving to actuate the clutch 1200 to 1500 times. You can drive the car 600 miles on the interstate and only shift the car 5 or 6 times and not break in the clutch.
