⚙️ Key Features

🔌 Function

Applies uniform clamping force around the oil-cooler hose to retain it on the nipple and maintain a leak-free transmission-oil circuit.

⚠️ Common Signs of Failure

• Transmission-oil seepage at the hose end
• Clamp corrosion, cracking or stripped adjustment mechanism
• Hose movement or blow-off under pressure
• Uneven clamp loading that cuts or distorts the hose
• Loss of transmission oil and elevated gear temperature

🛠️ Service Notes

• Fit a new clamp rather than reusing one that has been distorted, stretched or corroded; a band that has been drawn down onto a hose once rarely grips evenly again
• Use the correct size and type for the joint — an over-large clamp will not draw down evenly and can cut into a soft hose instead of gripping it
• Position the clamp fully over the spigot or pipe bead, clear of the hose end, and tighten only until the joint is secure; over-tightening crushes hoses, pipes and cable insulation
• Set the screw or head where you can reach it for later checks, and make sure the clamp is not resting anywhere it will chafe a neighbouring hose or harness
• Re-check tightness after the first run up to temperature, as hoses relax and settle once they have been heated
