O-ring voor de ZF automatische versnellingsbakoliepomp, die het pomphuis in de versnellingsbak afdicht.

De ZF-oliepomp is een intern aangedreven eenheid die de hydraulische druk genereert die nodig is om de koppelingsplaten in te schakelen en de koppelomvormer te regelen. Deze O-ring zorgt voor de hydraulische afdichting bij het pomphuis; verslechtering veroorzaakt ATF-lekkage en verlies van bedrijfsdruk, wat kan leiden tot onjuist schakelgedrag of doorslippen van de versnellingsbak.

Frequently asked questions

What does the RTC5103 O-ring do in the ZF automatic gearbox?

The RTC5103 O-ring seals the oil pump housing inside the ZF automatic gearbox. The pump generates the hydraulic pressure that engages the clutch packs and controls the torque converter, and this O-ring holds that pressure at the pump housing. It's the genuine Land Rover seal for the ZF pump.

Which Land Rovers with the ZF automatic gearbox does this O-ring fit?

This O-ring fits the ZF automatic gearbox on Land Rover Defender (1987-2006), Discovery 1, Discovery 2, Range Rover P38 and Range Rover Classic (1986-1994). It seals the gearbox oil pump housing across these ZF applications. Confirm your vehicle has the ZF automatic, not a manual, before ordering.

What happens if this gearbox O-ring fails?

A failed pump O-ring lets ATF leak past the pump housing and the gearbox loses hydraulic pressure. That typically shows as delayed or incorrect shifts, slipping, or loss of drive. Replacing this seal while the pump is accessible restores the pressure seal and avoids a repeat teardown of the ZF gearbox.
