The Multiquip 71466022624 is a genuine OEM Piston With Ring (OS=.25) MR8DY designed for the MR8DY series equipment. As a direct OEM component, it is manufactured to the same specifications as the original part, ensuring a correct fit into the engine block without guesswork or modification. This oversize (.25) piston is intended for engines that have been bored out during a rebuild, restoring proper compression and power output. If you are servicing an MR8DY unit, verifying the correct oversize specification before ordering is essential — this is the.25 oversize variant.
Key Features
- OEM Oversize Specification: — Manufactured to the exact .25 oversize dimension, matching bored-out cylinder tolerances for a proper seal and compression restoration.
- Ring Set Included: — Supplied as a complete piston and ring assembly, eliminating the need to source rings separately during an engine rebuild.
- Confirmed MR8DY Fitment: — Engineered specifically for MR8DY series equipment; verify bore size and oversize spec against your engine measurements before installation.
- Compression Recovery: — A correctly sized oversize piston restores lost compression caused by cylinder wear, bringing engine power and fuel efficiency back to proper operating levels.
- Genuine Multiquip OEM Part: — Sourced directly through the Multiquip OEM supply chain, ensuring material grade, ring groove dimensions, and pin bore sizing meet original design requirements.
A piston is the reciprocating component inside the engine cylinder that transfers combustion force to the crankshaft via the connecting rod. The piston rings seal combustion gases above the piston and control oil below it — when rings or the piston skirt wear, compression drops, oil consumption increases, and the engine loses power or becomes difficult to start. An oversize piston like this one is used when the cylinder bore has been machined slightly larger to remove wear scoring; the .25 oversize designation indicates the piston diameter is 0.25 mm larger than the standard bore dimension, filling the gap left by the rebore and restoring the tight seal necessary for efficient combustion.
