Frequently asked questions

What is the ERR559 tappet adjusting screw for?
The ERR559 tappet adjusting screw threads into the rocker arm on the 2.5L 200TDi diesel and sets the valve clearance. It bears on the valve stem, and a locknut holds the setting once the clearance is adjusted.
How many tappet adjusting screws does the 200TDi need?
The 200TDi has one adjusting screw per rocker arm, so a full set is eight, one per valve. Many buyers order a single screw to replace a stripped or damaged one, so check how many you actually need.

Fits the 2.5L 200TDi diesel in Defender (1987-2006), Discovery 1 (1989-1998) and Range Rover Classic (1992-1994 from VIN JA610294). It's the 200TDi rocker and tappet adjuster.
