What is the proper break in period?

We would like to see 500-600 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.

How Long Should A McLeod Clutch Last?

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.

What Are Musts When Replacing My Clutch?

1.Change the pilot bearing.

2.Break the clutch in according to the instructions provided.

3.Ensure proper bellhousing alignment.

4.Resurface the flywheel.

5.Inspect the entire clutch system including hydraulics and linkage.

What hydraulic bearing is right for me? 1300 vs 1400 series

The 1300 series bearing is designed to bolt onto the face of the transmission in placement of the factory bearing retainer. This series is commonly found on early model transmissions such as your Muncie,T-10, Super T-10,Saginaw,Top Loader (Both small shaft and Large Shaft) and GM T-5. All these transmissions have short inputshafts and generally have “A” dimensions with less than 3″ (in most cases)

The 1400 series bearing is designed for universal applications that McLeod Racing does not have a specific bolt on application but still has a 3″ or greater “A” dimension. This bearing is also commonly found in Ford T-5, TR-3550,TR-3650,T-45,T-56 for GM & Ford and TR-6060 transmissions.

What size master cylinder is recommended with a McLeod Racing internal Hydraulic Bearing?

We recommend a 3/4″ bore master cylinder with a 1″ stroke utilizing a 6:1 pedal ratio. Make sure to add a pedal stop if the master cylinder rod travels more than 1″ to eliminate over travel.
