I had my Bronco on the road about 6 weeks ago and tore up the C4 forward hub ID spline. Based my recent measurements this weekend I don't believe there was adequate torque converter hub engagement into the crankshaft adapter bore causing the hardened input shaft to "chatter" and eat the hub ID splines. The input shaft shows no damage. On Sunday I designed a new torque converter to flexplate adapter plate (replaces the wavy ring) to provide the basic engagement. Hope to have the adapter plate finished by Friday and reinstall the C4 this weekend. While I was rebuilding the C4 a couple of weekend ago I installed a Art Carr manual reverse shift valvebody with engine braking for 1st gear. Which means I know longer have to figure out a way to provide vacuum to the modulator. The Ford powerstroke vacuum pump that I mounted to the engine will only be used to provide a constant 25" vacuum to the brake booster.
Hope I don't tear the C4 up again. I have yet to start "turning up" the little diesel.
