DHS Equipment stocks this genuine Multiquip replacement to keep your generator running at full rated output.
Key Features
- Genuine OEM Valvetrain Precision — Manufactured to the exact geometry and surface hardness required for proper cam lobe contact and valve lift in DCA series diesel engines.
- Direct Engine Drop-In — Engineered to seat correctly in the tappet bore of the host engine block, maintaining the correct operating clearance straight out of the box.
- Broad DCA Series Coverage — Confirmed fitment across DCA25SSIU, DCA25SSI, DCA25SSI2, DCA25SSAI, DCA45SSIU2, DCA60SSAI, DCA60SSI2, and GEER and FEMA variants.
- Protects Valve Timing Accuracy — A correctly functioning tappet maintains consistent valve timing, which directly affects generator engine efficiency and stable power output under load.
- OEM Part Number Verified — Part number this part matches Multiquip's official parts catalog, eliminating cross-reference guesswork when ordering.
A tappet — also referred to as a valve lifter — sits between the camshaft and the valve stem (or pushrod) inside the engine. As the camshaft rotates, the tappet translates that rotational motion into the linear movement needed to open and close the engine's intake and exhaust valves at precisely the right intervals. When a tappet wears, develops flat spots, or fails entirely, valve timing becomes erratic, leading to rough running, loss of power, increased fuel consumption, and in severe cases, internal engine damage. Replacing a worn tappet promptly with the correct OEM part restores proper valve operation and protects the broader valvetrain from accelerated wear.
