Kato Excavator Final Drive Replacement: HD Series Travel Device Guide

Introduction

Kato excavators — built for demanding jobsites across Asia and beyond — use the HD series naming for their crawler range. When a travel device fails, matching the right final drive quickly keeps the machine in production.

This guide covers Kato final drive replacement across the HD series: the part numbers that matter, how to confirm fitment, and where to source a certified aftermarket unit.

Confirm Fitment Before You Order

Kato part numbers are model-specific. The HD820-3 and HD1430 use different travel device assemblies, so always confirm:

1. The full model name and generation (e.g., HD820-3)

2. The OEM part number stamped on your existing unit (e.g., 619-89300001, 162111A1)

3. Sprocket and frame hole counts

4. Whether the motor shaft and housing configuration matches your travel motor

Providing these details to BN Gears' sales team ensures you receive the correct unit the first time.
