The Multiquip 01265201 is a genuine OEM Piston Assembly 100+1.0 designed for MVH502DSB, MVH502DSB2, MQ41TDH, and MDR-9D equipment. As a direct OEM component, it is manufactured to the same specifications as the original part it replaces, ensuring correct fitment and consistent performance across compatible machines. Sourced directly through Multiquip's authorized parts network, this assembly is the correct choice when restoring engine integrity to your equipment.
Key Features
- Genuine OEM Construction — Manufactured to original equipment specification, with correct bore sizing and ring land geometry for the engines found in MVH502DSB and MQ41TDH applications.
- Oversized 1.0mm Bore Designation — The 100+1.0 specification identifies this as a first oversize piston, intended for use after cylinder bore has been machined 1.0mm over standard — install only when matched to the correct overbore.
- Cross-Equipment Fitment — Confirmed for MVH502DSB and MVH502DSB2 reversible plate compactors, MQ41TDH trash pump, and MDR-9D power trowel where applicable engine configurations match.
- Restores Compression and Power Output — A worn or damaged piston causes loss of compression, excessive oil consumption, and rough engine operation; replacing with this part restores proper cylinder sealing and engine output.
- Complete Assembly — Supplied as a full piston assembly, reducing the number of individual components to source and simplifying the rebuild process.
The piston is the reciprocating component at the heart of a four-stroke engine, converting combustion pressure into the mechanical force that drives the machine. It moves up and down within the cylinder bore, compressing the air-fuel mixture on the compression stroke and transmitting the force of ignition to the crankshaft via the connecting rod. When a piston wears, cracks, or scores, compression drops, oil enters the combustion chamber, and engine performance deteriorates rapidly. An oversized piston like the 01265201 — designated 100+1.0 — is fitted after the cylinder bore has been professionally honed or bored oversize, restoring the correct piston-to-wall clearance and bringing the engine back to full working condition.
