Rocker Shaft Stud - 300TDi is a cylinder head stud used in the rocker shaft assembly of the 300TDi 2.5L 4-cylinder turbo diesel engine.

The stud threads into the cylinder head and secures the rocker shaft pedestal brackets that support the rocker shaft. The rocker shaft in turn carries the rocker arms, which transfer cam lobe movement to open the inlet and exhaust valves. Correct installation torque on these studs is critical to maintaining rocker geometry and preventing oil leaks at the rocker cover.

Frequently asked questions

What is the rocker shaft stud used for?

The rocker shaft stud threads into the cylinder head and secures the rocker shaft pedestal brackets on the 2.5L 300TDi turbo diesel engine. The rocker shaft carries the rocker arms that transfer cam movement to the inlet and exhaust valves. It fits the Defender, Discovery 1 and Range Rover Classic 300TDi.

How many rocker shaft studs are needed for the job?

The 300TDi rocker shaft is held by several pedestal studs along its length, so a full rocker shaft refresh typically needs the complete set rather than one stud. These are sold individually, so count how many your engine uses before ordering.

Can the rocker shaft studs be reused?

Rocker shaft studs can usually be reused if the threads are sound, but replace any that are stretched, corroded, or damaged, since worn threads can't hold the correct clamping load. Correct installation torque matters for keeping rocker geometry true and preventing oil leaks at the rocker cover.
