Product Description
KATMOTO DRIVE TO-4 SAE 50 is a specialised powershift transmission and drivetrain oil meeting Caterpillar TO-4 / TDTO and Allison C-4 for off-highway powershift transmissions, torque converters, wet brakes, clutches and final drives. Its precisely controlled friction characteristics deliver consistent clutch and brake performance, with strong anti-wear (FZG), thermal and oxidation stability for durable, smooth drivetrain operation in construction and mining equipment.
Key Performance Features
| Controlled friction (TO-4)
precise frictional performance for consistent clutch and wet-brake operation. |
Anti-wear gear protection
high FZG load-carrying protects powershift gears and bearings. |
| Thermal & oxidation stability
resists thickening and deposits under high drivetrain temperatures. |
Anti-chatter wet brakes
minimises brake chatter and noise in oil-immersed brakes. |
| Shear stability
maintains viscosity for consistent powershift performance (no VI improvers). |
Multi-component use
suitable for transmission, torque converter, wet brakes and final drives. |
Applications & Performance Level
| Applications | Off-highway powershift transmissions, torque converters, oil-immersed (wet) brakes, clutches and final drives in construction and mining equipment where SAE SAE 50 Caterpillar TO-4 / Allison C-4 oil is specified. |
| Specification | Caterpillar TO-4 / TDTO — off-highway powershift drivetrain specification. Allison C-4 — transmission and torque-converter fluid specification. Komatsu KES 07.868 — suitable for Komatsu powershift drivetrain requirements. ZF TE-ML 03C — suitable for ZF off-highway transmission requirements. Vickers / Eaton (where TO-4 specified) — suitable for hydraulic functions specifying TO-4. |
| OEM Suitability | Caterpillar, Komatsu, Volvo, ZF and other off-highway powershift transmissions, wet brakes and final drives specifying SAE SAE 50 TO-4 / C-4. Follow the OEM manual for the correct grade. |
| Important Notice | Use only where the equipment manufacturer specifies this grade/type and a matching performance level. ”Suitable for” does not mean official approval unless separately certified. Always follow the OEM manual. |
