Rotor Arm for the distributor ignition system of the 3.5L V8 twin-carburettor petrol engine.

Mounted on the distributor shaft beneath the cap, the rotor arm turns with the shaft and routes the high-tension spark from the ignition coil to each spark plug terminal in firing sequence. A worn, burned or cracked rotor arm is a common cause of misfires, rough running and hard starting.

Frequently asked questions

What does the RTC3618 rotor arm do on a V8 Land Rover?
The RTC3618 rotor arm sits on the distributor shaft beneath the cap on the 3.5L V8 twin-carburettor engine. As the shaft turns, it routes the high-tension spark from the coil to each spark plug terminal in firing order. It's a key link in the distributor ignition on the Defender V8 and Range Rover Classic.
What are the signs the rotor arm needs replacing?
A failing rotor arm typically causes misfires, rough running, hard starting or stalling under load. The metal tip and central contact burn and erode over time, and the body can crack or track. Fitting the RTC3618 rotor arm restores a clean spark path through the distributor on the carburettor V8.
Is the RTC3618 rotor arm easy to fit?
Fitting the RTC3618 rotor arm is a straightforward DIY job. Lift off the distributor cap, pull the old rotor arm off the shaft and press the new one on, noting it only seats one way. No special tools are usually needed beyond releasing the cap. It's worth checking the cap at the same time.
How do I confirm the RTC3618 fits my distributor?
The RTC3618 rotor arm fits the 3.5L V8 twin-carburettor engine with the Stromberg-type distributor (14G, 15G and 17G) on the Defender and Range Rover Classic. Check your distributor type before ordering, since V8 rotor arms differ between carburettor and later injection distributors.
