Page 2: General Information
GENERAL INFORMATION The Hydra-Drive is a gearbox designed to make it possible to put a variable displacement pump on a Ford 4 x 4 truck with the TorqShift 6 transmission. The gear box attaches to a Chelsea 249 PTO output lowering it 8” and converting the output to a SAE-B 2 bolt. The Hydra-Drive is a 1:1 gearbox so the PTO ratio of 124% is not changed. -
