In this video, I discovered that the slave cylinder in my 4BT Cummins Ford went bad. It snowballs from there.
Old Transmission Setup: Small block ZF542 transmission with no synchros left, an internal clutch slave cylinder, and small block Ford clutch. Weak.
New Transmission Setup: Brand New ZF547 Powerstroke transmission rated for higher torque, better gear split for diesel engines, external slave, and a Southbend Clutch.
Parts ordered from Diesel Conversion Specialists.
The setup is so much better. More positive clutch engagement, stronger parts, and better drive-ability. Keep in mind, this may be overkill for your 4BT Cummins. This one is pushing 184hp and 485 ft. lbs. of torque to the wheels. That is real uncorrected power. At the flywheel those numbers translate to 225 hp, and 600 ft. lbs. of torque.
