The Multiquip 71477222720 Piston with Rings is a genuine OEM component designed for MT-86D rammers. Sourced directly from Multiquip, this part meets the exact engineering specifications of the original, ensuring a correct fit within the engine cylinder bore. If you are servicing an MT-86D rammer and need to restore compression and power delivery to spec, this is the correct OEM replacement to reach for.
Key Features
- OEM-Grade Compression Integrity — Manufactured to the original bore diameter and ring gap tolerances, maintaining the compression ratio the MT-86D engine was engineered to produce.
- Direct Engine Swap Fit — Designed to drop into the existing cylinder bore of the MT-86D rammer with rings pre-installed, simplifying the rebuild process.
- MT-86D Rammer Compatibility — Verified fitment for Multiquip MT-86D tamper/rammer equipment; always cross-reference part number 71477222720 before ordering.
- Restored Stroke Power — A worn piston or failed rings causes loss of compression, weak impact force, and hard starting; this assembly brings stroke performance back to original output levels.
- Fuel System Protection — Properly sealing rings prevent blow-by and oil contamination of the combustion chamber, protecting fuel economy and reducing carbon buildup over time.
The piston and ring assembly sits at the heart of the rammer's two-stroke or four-stroke engine, converting combustion pressure into the reciprocating force that drives the foot plate into the ground. The rings seal combustion gases above the piston while controlling oil film on the cylinder wall below — when they wear, compression drops, impact energy falls off, and the machine becomes difficult to start or run consistently. Replacing the piston with rings as a complete unit restores the tight cylinder seal needed for full compaction performance on granular soils, backfill, and trench work.
