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 input shafts 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, and T-56 for GM & Ford and TR-6060 transmissions.

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.

We use an Interference fit O ’ring on the ID of the adjuster screw that grabs onto the steel guide tube of the transmission. With this O ’ring plus the pressure of the bearing assembly pressing against the pressure plate this force, forces the body of the bearing assembly to lock up against the face of the transmission. The physical bearing spins independently from the bearing body behind it and there is very little to no windage to cause the bearing body to spin.

None of the Muncies came from the factory with an oil seal in the bearing retainer. They use a “Slinger Nut” that slings the oil to the outside edges of the bearing retainer to then drain at the bottom of the retainer and go back to the case. Our bearing mimics this factory design.
