Case Study 6 | Dump Truck Gear Oil Filtration

Lubemaster Cleans Gear Oil in CAT 793 Dump Truck Differentials

A German Creek coal mine tested the Lubemaster OS600 fitted with a 5μm final filter to clean gear oil in CAT 793 dump truck differentials.

The dump truck differentials held approximately 800 litres of gear oil. During the trial, the Lubemaster system achieved Caterpillar cleanliness specifications within only three hours of filtration.

In addition, continuous oil circulation inside the differential created a washing effect. This process flushed contamination from internal surfaces and helped improve overall oil cleanliness.

Customer Feedback After Trial Completed

“G’day Fellas
The oil sample results for the modified filter cart trial on RD538 that was carried out on 16/09/2008 have arrived from the lab. In summary, the objective to achieve the recommended 18/15 ISO count (Caterpillar recommendation) was achieved and exceeded. Results are as follows;
Commenced at 10.00 AM, centrifuge only, three way valve switched to bypass filter, oil temperature at 64 deg C.

End trial at 1600 hrs. Total filtering time = 6 hours.

In summary, the modified cart performed well. The inclusion of the larger capacity filter element made a drastic improvement in oil clean up time. The target level was achieved after only 90 minutes of operation.”

    Benefits of Dump Truck Gear Oil Filtration

    High-efficiency gear oil filtration helps mining operations maintain cleaner oil and reduce wear inside differentials and drive-line components.

    Key benefits include:

    • Removes harmful contamination particles
    • Achieves ISO cleanliness targets quickly
    • Improves differential reliability
    • Extends gear oil service life
    • Reduces component wear
    • Minimizes maintenance costs
    • Supports cleaner operating conditions
    • Reduces unnecessary oil replacement

    High-Efficiency Filtration for Mining Equipment

    The Lubemaster OS600 is designed for demanding mining and heavy equipment applications.

    By continuously circulating and filtering the oil, the system removes contamination and restores oil cleanliness throughout the differential system. As a result, mining operators can improve lubrication performance and reduce contamination-related failures in critical equipment.
