You confirm the excavator model and serial number to ensure fitment
We verify the part number and stock status and send a photo of the current unit
You place the order with payment terms agreed (T/T, Western Union, etc.)
We provide tracking and shipping documents upon dispatch

Quality Control

Checks Before Loading

Each unit is tested under load for torque output and noise levels before packing
Internal components are inspected for machining tolerances using calibrated gauges
Seals and gaskets are visually checked for defects before assembly
Photos and test reports are sent upon request before shipment

Customisation

What Can Be Changed

Custom mounting flanges or shaft extensions available upon request
Alternative seal kits for high-temperature or abrasive environments
Reconditioning of used units with new seals and bearings (if available)
Labeling with customer-specific part number or barcode

Honest Comparison

How It Compares With the Alternatives

OEM travel motor from the original excavator manufacturer	This unit is significantly cheaper and ships faster, but may not carry the same brand warranty or lifetime guarantee
Generic hydraulic motor from a non-specialist supplier	This unit uses European-imported CNC tools and has consistent tolerances, reducing risk of premature failure
Used or reconditioned motor from a local repair shop	This unit is new, tested, and comes with a 180-day warranty, avoiding hidden wear or internal damage

Use Guide

Using It Well

Inspect all seals and mounting bolts before installation to prevent hydraulic leaks
Use only the recommended hydraulic fluid type and viscosity for the travel system
Bleed the hydraulic system thoroughly after installation to remove trapped air
Monitor for unusual noise or vibration during initial operation; stop and inspect if abnormal
