Product Description
L77150 Case Hydraulic Pump
New Aftermarket Replacement Hydraulic Pump
Overview
The L77150 hydraulic pump is a replacement hydraulic pump designed for Case construction and wheel loader hydraulic system applications. Hydraulic pumps used in heavy wheel loader equipment are responsible for maintaining hydraulic oil flow and system pressure for steering circuits, loader lift systems, bucket controls, and auxiliary hydraulic functions.
This replacement hydraulic pump is intended to help restore hydraulic system performance in demanding construction, material handling, aggregate, and industrial work environments.
Known Equipment References
Public aftermarket references associate the L77150 hydraulic pump with several Case wheel loader applications including:
- Case W11
- Case W11B
- Case W14
Case wheel loaders are commonly used in construction sites, aggregate yards, industrial loading operations, snow removal, material handling, and heavy-duty earthmoving applications where hydraulic system reliability is critical.

Wheel Loader Hydraulic Applications
Hydraulic systems used in wheel loaders operate under continuous pressure loads and severe working conditions. Depending on machine configuration, hydraulic pumps may support steering systems, bucket lift cylinders, tilt circuits, auxiliary attachments, hydraulic implements, and transmission-related hydraulic functions.
Hydraulic pumps exposed to vibration, contamination, heat, and extended operating hours may eventually develop internal wear that can affect overall machine performance.
Possible Hydraulic Issues
- Slow bucket lift response
- Weak hydraulic power
- Pressure loss during operation
- Hydraulic overheating
- Noisy hydraulic pump operation
- Inconsistent steering response
Typical Hydraulic Functions
- Loader arm hydraulics
- Bucket tilt functions
- Steering circuits
- Auxiliary hydraulic controls
- Attachment operation
- Material loading functions
