Frequently asked questions

What does the RTC3614 rotor arm do on a 4-cylinder Land Rover engine?

The RTC3614 rotor arm sits on the distributor shaft inside the Lucas distributor cap, routing the high-tension spark from the coil to each cap terminal in firing order as the shaft rotates. It's a service item on the 2.25L and 2.5L 4-cylinder petrol engines in Series and Defender.

Why do rotor arms fail, and what are the symptoms on a Series or Defender?

Rotor arms fail through carbon tracking, cracks in the rotor tip, or corrosion of the contact point. On Series and early Defender engines, typical signs are intermittent misfires, hard starting, and poor idle, usually appearing together with a worn distributor cap.

Does this rotor arm fit all Series and Defender 4-cylinder engines?

The RTC3614 fits 2.25L and 2.5L 4-cylinder petrol engines with a Lucas distributor, from engine suffix D onwards. It covers Land Rover Series 2, Series 2A, Series 3, and Defender from 1983 to 2006. It doesn't fit diesel engines or models that don't use a conventional distributor.
