ABSTRACT:
A hydraulic tool for disassembling blowers on certain diesel engines such as those known as Detroit Diesel Engines includes a pair of hydraulically operated pistons that are pressurized by a manually operated hydraulic pump which translates the pistons at the same time to force the shafts of the gears in the blower to slide off of their respective shafts at the same time and onto the respective pistons. This captures the gears and prevents damage to the blower and its component parts. The hydraulic tool includes a platen that is bolted to the casing of the blower by utilizing the tapped holes that are used to bolt the end cover plate of the blower.
