Frequently asked questions

What is the RTC4480 wiper drum adaptor and what does it do?

The RTC4480 is a splined wiper drum adaptor for the windscreen wiper system on Land Rover Series 3 and Defender. It seats on the splined wiper drive spindle and forms the connection between the spindle and the wiper arm, transferring drive torque and setting the arm's alignment on the splines.

Which models and VIN range does this wiper adaptor fit?

This splined adaptor fits Series 3 front wash/wipe systems and Defender from 1986 to 2006, within VIN range FA434631 to 1A622423. The splined-ferrule design is specific to that build window, so check your VIN against the range before ordering, as the wiper spindle fitting changed on later vehicles.

How many adaptors are needed and how do they fit?

One adaptor is fitted per wiper spindle, so you'll need one for each wiper position being renewed. It typically replaces a worn or stripped splined ferrule that lets the wiper arm slip on the spindle. The arm pulls off the old adaptor and the new one presses onto the splines to restore positive drive.
