## 🔌 Function

The impulse limiter absorbs and restricts sudden pressure impulses and shock loads in the steering system so they are not transmitted through to the helm or steering components. This protects the steering circuit and gives smoother, more controlled steering response.

## ⚠️ Common Signs of Failure

-   Harsh feedback or kickback felt at the helm when the drive loads up
-   Notably increased steering effort or stiff, uneven steering action
-   Fluid weeping or seepage at the limiter body or its connections
-   Loss of steering pressure or spongy, inconsistent helm feel
-   Knocking or hydraulic hammering noises during rapid steering movements

## 🛠️ Service Notes

-   Fitted in the steering circuit for twin-installation applications, and can be used together with kit 1140610 when adding power steering to an earlier drive — check both parts are correct for the installation rather than ordering this alone
-   Supersedes earlier limiters 828858 and 828914, so an order placed against either old number should be filled with this part
