YNF17467 Ball Guide AP2D36 Hydraulic Pump Ball Guide for Excavator Rotating Group

The YNF17467 Ball Guide, designed for the AP2D36 hydraulic pump, is a crucial component within the rotating group assembly. It holds and guides the piston shoes, ensuring accurate contact with the swash plate and maintaining stable hydraulic timing. A worn or deformed ball guide can lead to misalignment, increased friction, unstable pressure output, and accelerated wear of other pump components.

Manufactured from heat-treated alloy steel and finished with precision CNC grinding, the YNF17467 ball guide provides excellent hardness, structural stability, and a smooth operating surface. This enhances piston shoe tracking accuracy, reduces internal leakage, and improves the overall efficiency of the AP2D36 pump—especially under long-hour, heavy-duty excavator operations.

It is widely used by hydraulic pump rebuilders, equipment maintenance workshops, and aftermarket parts distributors. Replacing the ball guide during overhaul significantly improves pump reliability and extends component life.
