Vickers 388015 Hydraulic Pump Shaft Retainer Assembly

Vickers 388015 Hydraulic Pump Shaft Retainer Assembly is a heavy‑duty shaft retention and alignment component used in hydraulic pumps, motors, and power transmission equipment to secure rotating shaft parts and maintain precise positioning. Designed for 2 in shaft assemblies with a 1/2 in single‑side keyway, this shaft‑mounted, precision‑machined metal retainer supports reliable operation in hydraulic power units and industrial machinery. It is commonly applied during equipment repair, pump rebuilds, and preventive maintenance to replace worn shaft retention parts, with applications spanning hydraulic vane pumps, hydraulic motors, and gear drive assemblies. Common replacements include the Vickers 255533 Pump Shaft Assembly, and equivalents from Eaton Vickers or Parker.
