English Product Introduction

1
708‑8F‑31540 final drive travel motor assembly is specially designed for Komatsu PC200‑7 and PC220‑7 excavators. It fully matches OEM mounting holes, hydraulic ports and pipeline connectors, supporting direct whole‑unit replacement without chassis modification.
2
It consists of swash plate piston motor and two‑stage planetary reduction gear set, featuring large reduction ratio and strong output torque. The machine delivers powerful traveling performance on slopes and muddy ground without slipping. Built‑in hydraulic parking brake locks the travel unit automatically after shutdown to prevent sliding on steep terrain for higher safety.
3
Gears, cylinder blocks and pistons are made of high‑strength alloy steel with heat quenching and precision grinding, offering excellent wear and impact resistance. It effectively avoids common failures such as gear breakage, piston scratch, internal leakage and weak traveling under long‑term complex road conditions.
4
The assembly is equipped with full set of high‑pressure FKM oil seals for dust and mud resistance, preventing oil leakage during long outdoor operation. Thick cast steel housing resists collision and extrusion to adapt harsh construction site environments.
5
Every unit passes full inspections of pressure, torque and brake performance before delivery. As core chassis replacement spare part for 20‑ton Komatsu ‑7 series excavators, it thoroughly solves malfunctions including one‑sided weak travel, low speed, abnormal noise, oil leakage and brake failure.
