Short Description
High-performance aftermarket 167-1154 (CAT Reman: 10R-0524) Axial Piston Variable Displacement Hydraulic Pump, engineered to serve as a 100% seamless drop-in alternative for Caterpillar 140H, 143H, 160H, and 163H Motor Graders. Manufactured to exact OEM dimensional and hydraulic tolerances, this 85cc-base implement pump delivers outstanding pressure retention, fast load-sensing feedback, and maximum reliability under heavy grading operations.
Key Highlights
-
Precise Motor Grader Calibration: 100% interchangeable with Caterpillar factory part number 167-1154 and Reman group 10R-0524. Guarantees zero-alignment or port mating issues on H-series frames.
-
85cc High-Flow Performance: Provides excellent volumetric efficiency tailored precisely to match the speed and torque requirements of CAT 3176C or 3306 diesel engine platforms.
-
Advanced DFR/DFR1 Valve Control: The integrated pressure and flow compensation regulator is factory-set to ensure seamless synchronization of the moldboard lift, blade sideshift, and steering articulation.
-
Built for Continuous Duty: Upgraded internal rotating components (hardened pistons, bimetal cylinder block, and high-load cradle bearings) reliably manage severe hydraulic shock loads during hard-packed soil or gravel grading.

FAQ
Q1: Can this aftermarket 167-1154 pump replace my original unit if the tag lists Reman number 10R-0524? A: Yes, 100%. 10R-0524 is Caterpillar’s official designation for the remanufactured version of the brand-new 167-1154 pump group. Our premium replacement matches both references identically, ensuring the exact same mounting flange, splined shaft, and oil port configurations.
Q2: Is the control valve pre-calibrated for CAT 140H grader standby pressures? A: Yes. The load-sensing regulator valve built onto our 167-1154 pump assembly is fully dynamically calibrated on a hydraulic test bench to match factory CAT H-series standby and differential pressure margins, allowing for smooth, immediate blade controls upon field installation.
