Multiquip 42612 Fixed Gear Charge Pump 19CC & 8CC - OEM Replacement Part

This dual-output fixed gear charge pump delivers pressurized hydraulic fluid to the hydrostatic drive system of Multiquip ride-on trowels, maintaining proper flow to both the drive motors and steering cylinders. The 19CC and 8CC gear sections work together to supply hydraulic power to independent drive motors that control the blade spider assemblies, while also feeding the palm-grip joystick steering system that operates three hydraulic steering cylinders within the machine frame.

The hydrostatic system on these trowels holds approximately 8 gallons of hydraulic oil and relies on consistent charge pump performance to maintain blade rotation speed and steering response during concrete finishing operations. Loss of hydraulic pressure, erratic blade speed, or unresponsive steering controls often indicate charge pump failure requiring replacement.

This pump is a critical component in the engine-powered hydrostatic system that couples drive motors to spider assemblies equipped with 6 blades per rotor. Compatible with Multiquip hydrostatic ride-on trowels equipped with Hatz 4H50TIC diesel engines.
