Description
Overview:
This Trailer Overrun Coupling Damper for AL-KO 60S/2 (MPN 764 129) is a service replacement damper designed to restore smooth, controlled operation of the overrun coupling on trailers built with the AL-KO 60S/2 housing. The damper is a sealed, steel-bodied hydraulic unit that moderates the fore-and-aft movement of the drawtube during braking and acceleration. By controlling this motion, it helps prevent brake snatch, reduces stress on coupling components and improves towing comfort and consistency. Intended for professional maintenance and repair, it is used when the original damper has weakened, seized or is otherwise no longer delivering the required resistance. Suitable for use on braked trailer and caravan installations where the AL-KO 60S/2 overrun device is fitted, including general duty, plant and leisure trailers found in fleet, hire and trade applications.
Key Features:
- Replacement overrun coupling damper for AL-KO 60S/2 assemblies
- Steel-bodied, sealed hydraulic design for consistent damping performance
- Controls drawtube travel under braking and acceleration to smooth coupling action
- Helps reduce shock loads and wear on the coupling head, drawtube and brake linkages
- Configured to suit the stroke and mounting geometry of the AL-KO 60S/2 overrun device
- Maintenance-free sealed unit with no routine adjustment required
- Supplied as a single damper for one coupling service
- Suitable for workshop, fleet and roadside service replacement following manufacturer procedures
Typical Applications:
Installed within the overrun device on the trailer A-frame/drawbar, between the coupling head and chassis, to regulate the compressive and return movement that actuates the trailer brakes. Fits AL-KO 60S/2 overrun couplings commonly found on small to medium braked trailers, general duty and plant transport trailers, and some caravans using the 60S/2 housing. Replace when the coupling action becomes harsh, oscillates, or fails to return smoothly.
