Product Advantage

The WHST40-03 Assignment Plate (Pump) is a replacement plate for World harvester 45cc HST hydrostatic transmission pump assemblies. It is used for pump identification, assembly reference and reinstallation alignment during HST overhaul. Specifications reference Φ90 × bore φ28 × H5 mm, 0.15–0.17 kg, stainless/steel/iron per batch. MOQ 1 pc; OEM/custom nameplate available.


Allocate high-pressure oil circuit: Accurately switch between high-pressure and low-pressure oil circuits to ensure stable operation of the hydraulic system.	Reduce leakage and improve efficiency: High precision distribution surfaces can significantly reduce internal leakage and improve walking efficiency.	Protect the pump body components: maintain a reasonable fit between the pump cylinder body and plunger group, and extend the overall life of HST.	Improve overall handling: Ensure stable driving and steering response of the harvester in muddy and paddy fields

Product Operate Guide

When to replace:

Original plate rusted, faded or unreadable for pump/displacement identification
HST pump teardown and rebuild, old plate bent, elongated or missing
Used harvester rebranding, export documentation, fleet plate standardization

Installation tips:

Release HST pressure and isolate power; remove old plate, mark orientation and screw positions; fit new WHST40-03 to original holes, torque screws to model spec; if internal HST parts (cylinder block, valve plate, plunger) are also worn, repair them separately rather than relying on plate replacement.
