Multiquip 352437330 Piston End MT-85 - OEM Replacement Part

The piston end assembly is a critical engine component that converts combustion energy into the reciprocating motion required to drive the MT-85 series rammer's compaction system. This OEM replacement part maintains the precise tolerances and performance specifications needed for the Robin EC12-G air-cooled 2-stroke gasoline engine, which produces 4.0 hp at 4,000 rpm and delivers 6.96 cubic inches (114cc) of piston displacement. The MT-85 rammer operates at 670 blows per minute with 4,410 lbs of impact force per blow, making reliable piston operation essential for maintaining optimal compaction performance.

During routine maintenance, inspect the piston end for scoring, excessive wear, or carbon buildup that can result from the high-speed operation inherent to two-stroke engines. The MT-85H is designed to run at 4,000 rpm continuously, and any piston wear will directly impact the tamping action and engine performance. Failed or worn piston ends typically present symptoms including loss of compression, reduced power output, difficulty starting, or irregular tamping rhythm.

This piston end is compatible with the following Multiquip rammer models:

• MT-85H
• MT85HS
