## ⚙️ Key Features

-   Genuine Volvo Penta reverse-gear oil-cooler clamp
-   Two clamps used with the applicable hose connection
-   Matched to hose 21148614
-   Used across specified HS25, HS45, HS63 and HS80 arrangements
-   Correct clamp position and tightening are essential to prevent oil loss
-   Engine type: Marine hydraulic reverse gear / transmission

## 🔌 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
