Aftermarket tappet (valve lifter) 5I-7627A — a direct replacement for the Caterpillar 5I-7627 tappet. It fits the Caterpillar 3066 / S6K / C6.4 diesel engine family (also 3064 / C4.2), commonly used on CAT 311 / 312 / 320 excavators. The tappet transfers camshaft motion to the pushrod / valve train. When its face or bore wears, valve clearance drifts, the engine gets noisy and power drops; badly worn tappets can score the camshaft lobe. Supplied as a single tappet; order the quantity you need for the full set. Confirm the removed number and engine reference before ordering.
