Lehman Predator / Dominator Differential

[DPK]

Does anyone know the technical designation of the Ford differential used by Lehman in the subject trikes? I need the car model, year & drum diameter in order to order Speedbleeders.

Also, I've installed a 10 psi residual pressure valve in the drum brake fluid line. I've been told that use of the valve requires a special bleeding procedure. Does anyone know if this is correct and if so, what is the procedure?

The rear axle housing should be stamped with a number. The axle housings were from 6.75 Pinto, Bobcat, Mustang II of the early 80's. They modified the axle housings to use small 9" Ford axle bearings. The brakes are 9" Ford also.
The bleeding process is straight forward, start with the mastercylinder and then the left rear wheel and then the right. I usually do this manually and don't use speed bleeders myself. DOT 3 or 4 premium fluid.

Jim,

Thanks for the information.
