ZF 0632.311.606 HOSE CLAMP | OEM Genuine Part

Overview

The ZF 0632.311.606 HOSE CLAMP is a critical OEM genuine fastening component engineered for high-pressure fluid circuits within ZF construction machinery transmissions. This clamp secures hydraulic and lubrication hoses to their respective ports, preventing pressurized oil from escaping the system. Positioned along the transmission’s external oil routing lines, the 0632.311.606 clamp works in concert with the 4108101140 HOUSING and the 0501211694 MOTOR assembly to maintain consistent fluid pressure. Without this clamp, hose connections can loosen under vibration, leading to immediate loss of lubrication. The SKU 0632.311.606 is a direct replacement for the original factory part, ensuring a precise fit and reliable sealing force.

Symptoms of Failure

• Hydraulic oil weeping at hose connections: A worn or corroded 0632.311.606 clamp cannot maintain uniform pressure on the hose barb, causing slow seepage of transmission fluid around the fitting.
• Intermittent gear slipping under load: When the clamp fails to seal, the transmission loses hydraulic pressure to the clutch packs, resulting in momentary loss of torque transfer during heavy digging or lifting.
• Audible air ingestion or whining noise: A loose clamp allows air to enter the suction line, creating cavitation in the 0501314793 COVER assembly, which produces a distinct high-pitched whine from the pump.
• Visible oil spray on the transmission housing: Complete clamp failure can eject a stream of hot oil onto the 0501314799 BUSH and surrounding components, leaving a slick residue that attracts debris.

Technical Specifications

Compatibility

This hose clamp is designed for use in ZF’s heavy-duty powershift transmission series, specifically the WG180, WG200, and WG210 models found in wheel loaders, excavators, and graders. It also fits select 4WG-200 and 6WG-200 variants where external oil cooler lines are present. The clamp interfaces directly with the 4108101140 HOUSING port and the 0501211694 MOTOR inlet hose. For transmissions equipped with the 0501314793 COVER, this clamp secures the return line. Always verify the hose outer diameter before installation; the 0632.311.606 clamp accommodates standard ZF ¾-inch and 1-inch hydraulic hoses.
