The Multiquip 71427022581 is a genuine OEM Piston With Ring.50MM L40AE-DR designed for the L40AEDR. As a direct OEM component sourced through Multiquip's authorized parts network, this piston and ring set is manufactured to the exact dimensional tolerances required for proper compression and engine performance. The.50MM oversize specification makes it the correct choice for engines that have been bored to accept an oversized piston during reconditioning. Confirm your engine's bore size before ordering to ensure this is the right specification for your application.
Key Features
- OEM-Spec Oversize Tolerance — Manufactured to the exact .50MM oversize specification, ensuring correct piston-to-wall clearance in a reconditioned L40AE-DR engine bore.
- Complete Piston and Ring Set — Supplied as a matched assembly, so the ring and piston are sized and seated to work together straight out of the box.
- Direct OEM Replacement — Genuine Multiquip part this part installs directly into the L40AEDR without additional machining beyond the required bore work.
- Compression Integrity — A correctly fitted piston and ring set maintains proper cylinder compression, supporting consistent power output and efficient fuel combustion.
- Engine Rebuild Confidence — Using the correct OEM oversize piston during a rebuild prevents premature wear, blow-by, and oil consumption caused by improper fitment.
A piston and ring set is at the heart of the engine's power stroke. The piston transfers combustion energy to the crankshaft, while the rings seal the combustion chamber, control oil consumption, and transfer heat away from the piston crown into the cylinder wall. An oversize piston like this .50MM variant is used when an engine cylinder has been bored out to restore a true, round surface after wear or damage. When a piston or its rings wear out, the result is lost compression, increased oil burning, reduced power, and hard starting — all signs that an engine rebuild with the correct oversize piston is needed.
