Transgear 903 S3 30

Veedol Transgear 903 S3 30 is a heavy duty powershift transmission and hydraulic lubricant designed and recommended for applications requiring oils meeting the Allison C-4 specification. It is formulated from premium base stocks and a select additive system to meet the challenging demands of transmissions and hydraulics of modern off-highway, mining and construction equipment.
Features/Benefits:
- High resistance to oxidation and thermal degradation helps resist the effects of oxidizing agents and thermal stress, thereby extending the life of transmission components.
- Excellent wear protection safeguards gears against wear and pitting, helps prevent premature failures, and reduces maintenance costs.
- Superior frictional characteristics offer optimum balance between static and dynamic frictional characteristics for improved transmission performance.
Performance Specification:
- Allison C-4
- Komatsu KES 07.868.1
Application:
- Recommended for use in power-shift transmissions, hydraulic systems, and hydrostatic drives of construction and off-highway equipment where SAE 30 grade oil meeting Allison C-4 specification is specified.
