Multiquip 21395 Pump Control Rod Hex 12.38L - OEM Replacement Part

This hexagonal pump control rod manages hydraulic pressure and flow control in Multiquip ride-on trowel machines, providing precise operator input transmission from the control mechanism to the hydraulic pump assembly. Measuring 12.38 inches in length, the hex configuration ensures positive engagement and prevents slippage under operational loads, critical for maintaining consistent blade pitch control during finishing operations.

The pump control rod is a wear-critical component in ride-on trowel hydraulic systems. Over time, repetitive motion and hydraulic pressure cycles can cause wear at connection points, leading to imprecise control response, delayed blade pitch adjustment, or complete loss of hydraulic control. Regular inspection during routine maintenance intervals is recommended, with immediate replacement if any play, bending, or worn hex surfaces are detected.

This part is compatible with the following Multiquip models:

• HTX-44K4
• STX55J6
