BALL - ROCKER ARM (Hyster HY189614)

A worn rocker arm ball can cause uneven valve action and audible tapping from the valve train. This aftermarket replacement part references Hyster as the OE maker and cross-references part number HY189614. The ball serves as a pivot point between the rocker arm and the valve stem, allowing smooth rotational movement during operation. If the ball surface becomes pitted or worn, valve clearance may drift out of specification, leading to reduced compression. In a typical overhead-valve configuration, the ball endures repeated impact loads from camshaft motion. The item ships at approximately 0.04 pounds. Verify the serial number or application, then call (562) 693-7748.
