Frequently asked questions

What is the Rocker Arm Bush (ERR1203)?
The Rocker Arm Bush (ERR1203) is the bearing bush pressed into the rocker arm, carrying it on the rocker shaft. It lets the rocker pivot smoothly on the 200TDi and 300TDi diesel valvetrain in the Land Rover Defender up to 2016, Discovery 1 (1989-1998), and Range Rover Classic.
Where does the bush sit in the valvetrain?
The bush sits inside the bore of each rocker arm, forming the bearing surface between the arm and the rocker shaft on the 200TDi and 300TDi engine. It carries the pivot load as the pushrod lifts. Fitted across the Land Rover Defender up to 2016, Discovery 1, and Range Rover Classic.
How many bushes are needed for a rocker overhaul?
A rocker overhaul typically needs one bush per rocker arm, so the 200TDi or 300TDi engine uses several ERR1203 bushes for a full set. This part is sold individually. Press worn bushes out and new ones in when refurbishing the rocker shaft assembly.
