Frequently asked questions

What is the tappet screw (506814) used for?

The tappet screw is the adjusting screw that sets valve clearance. It threads through the rocker arm with a UNF thread, bears on the pushrod, and locks against its locknut. It's fitted to the 2.25L 3-bearing engine on the Land Rover Defender (up to 2016) and Series 2 and 3.

How many tappet screws are needed for a full valve adjustment?

Typically one tappet screw sits in each rocker arm, so a four-cylinder engine usually takes eight for a complete set. Many people renew them all when the threads or locknut seats are worn, keeping valve clearances consistent across the engine.

Does this tappet screw fit all Series 3 petrol engines?

Not all. On the Series 3 2.25 petrol it fits engines prefixed 901/904 and 361/364 with suffix A and B only. It otherwise suits the 3-bearing crankshaft engine on the Defender and Series 2 and 3, so check your engine prefix before ordering.

What's involved in fitting the tappet screw?

Fitting is part of a valve clearance adjustment. You typically slacken the locknut, turn the screw against a feeler gauge to set the clearance on the pushrod, then hold it and retighten the locknut. A basic spanner and feeler gauge are usually all that's needed.
