For many years Riverhawk, has provided hydraulic hub installation kits. These kits include but are not limited to: hydraulic pushers, pullers, pump kits and fittings. In conjunction with the installation kits, Riverhawk manufactures gauge sets and lapping tool sets used to check and correct the taper surfaces on shafts and their mating parts. Our history of applications range in shaft sizes from 1.75” up to 12”. Each application is reviewed by engineering, where standard or custom tooling is selected and designed for ease of installation or removal.

Although our designs are intended for proficiency, our number one concern is always safety. Hydraulic pushers and pullers are designed with a pressure rating calculated using thread engagement and overall tool profile with a marginal factor of safety.

Recently we received a request for a pusher solution that could install multiple thrust disks and couplings on a single shaft, that being at different horizontal positions. Each application was reviewed and a single pusher with multiple custom extensions was designed. This tool met the requirements needed and also helped with an easy installation.
