ZF 3312107002 - Oil Cooler for ZF Yanmar 6LP / ZF 63-68A, Replaces HBW 360/450/630, 250 L/min, 6 bar
The ZF 3312107002 Oil Cooler is a robust marine-grade gearbox cooling unit engineered for use with ZF Yanmar 6LP engines and ZF 63/68A transmissions. Designed to replace older HBW models (360, 450, 630), it delivers superior oil cooling capacity of up to 250 L/min while withstanding pressures up to 6 bar. Built with a corrosion-resistant aluminum alloy housing, it ensures long-term reliability in marine environments. The unit integrates a replaceable oil filter and supports smooth hydraulic shifting for efficient marine propulsion performance.
Key Features:
- OEM replacement for HBW 360 / HBW 450 / HBW 630
- Compatible with ZF Yanmar 6LP engines and ZF 63/68A transmissions
- Cooling capacity: up to 250 liters per minute
- Max operating pressure: 6 bar (87 psi)
- Lightweight, seawater-resistant aluminum alloy casing
- Case-hardened, precision-ground gear teeth for durability
- Thrust bearing handles full propeller load (forward/reverse)
- Hydraulic shifting system with push-pull cable compatibility
- Replaceable oil filter cartridge for easy maintenance
- Compatible with various propulsion systems (jets, surface drives)
- Built-in “SUPERSHIFT” clutch control for smooth shifting
- Designed to meet ISO 9001 manufacturing standards
