Eaton Hydraulic Motor

Eaton Hydraulic Motor

This Eaton 5433 series hydraulic piston motor is a critical component for the hydraulic systems of concrete transit mixers, specifically for drum rotation. It is engineered to handle the demanding environment of concrete applications, providing reliable and durable power to ensure the drum maintains a consistent speed, whether the truck is in transit or idling. This motor is a common replacement part for maintenance on McNeilus, Con-Tech, and Terex mixers when the original motor fails or loses efficiency, leading to inconsistent drum speed or system failure. Its robust cast iron construction and design features, such as a large case drain port and a standard SAE C 4-bolt mounting flange, make it a suitable OEM replacement.

Key Features

• Fixed-displacement design for consistent drum speed
• High-pressure capability up to 420 bar (6000 psi) nominal pressure
• Advanced cylinder barrel design permits high speed and pressure
• SAE C 4-bolt mounting flange for secure installation
• Cast iron body for durability in heavy-duty applications
• 21-tooth, 16/32 pitch splined output shaft

Fits These Mixers
