About CONTROL VALVE MK3 ( SQUARE SHAFT) 1681789M91

The 1681789M91 control valve MK3 (square shaft) is a critical hydraulic component in many Massey Ferguson tractors. It regulates the flow of hydraulic fluid between the pump and the tractor™s hydraulics system, enabling smooth control of hydraulic functions like lifting, tilting, and draft control.

Being a Mark III (MK3) valve, this component is designed for MK3-type hydraulic pump housings, and its square shaft design provides reliable mechanical engagement and translation of operator control inputs into valve movements. The square rod enhances torque transfer and improves handling under heavy use.

Its 198 mm length and compact, lightweight form factor (‰ˆ 0.22 kg) make it well suited for retrofitting into existing MK3 pump assemblies, particularly during maintenance or repair. Designed to be a direct replacement for earlier or worn-out valves, it requires minimal modification when installed, which reduces downtime during maintenance.

The valve assembly typically includes precision-machined components, O-rings, and a roller & pin mechanism to maintain high sealing integrity and control smoothness.

This valve is compatible with a broad set of Massey Ferguson tractor models ” spanning various series ” making it a versatile part for agricultural and industrial applications.

Because of its widespread compatibility and reliable design, this control valve is frequently stocked by aftermarket parts suppliers, often at significantly lower cost than OEM units. Despite being aftermarket, many versions deliver robust performance with long service life, making them a practical choice for both restoration projects and routine maintenance.
