O-ring voor de vloeistofaanzuigbuis van de ZF-automaat met vier versnellingen.

Dicht de verbinding af bij de aanzuigbuis die automatische transmissievloeistof uit het carter in de pomp zuigt, waardoor de drukintegriteit van de vloeistofaanzuiging in het transmissiehuis behouden blijft. Wordt vernieuwd wanneer het carter of de aanzuigbuis wordt verstoord tijdens een vloeistof- en filteronderhoud of een revisie van de transmissie.

Frequently asked questions

What is the RTC5818 O-ring used for?
The RTC5818 O-ring seals the fluid suction (pick-up) pipe inside the ZF four-speed automatic transmission. It maintains pressure integrity where the pipe draws transmission fluid from the sump into the pump, and is renewed whenever the sump or suction pipe is disturbed.
When should this transmission O-ring be replaced?
Replace this O-ring whenever the transmission sump or suction pipe is removed, such as during a fluid and filter service or a gearbox overhaul. It's typically renewed as standard rather than reused, since a disturbed O-ring can leak or lose pump pressure in the ZF automatic transmission.
Which Land Rovers use this ZF automatic transmission O-ring?
This O-ring fits Land Rover models with the ZF four-speed automatic transmission: Defender, Discovery 1, Discovery 2, Range Rover Classic and Range Rover P38. Some Discovery 1 and Range Rover Classic applications carry VIN breaks, so check your chassis number if unsure.
