Multiquip 1612340301 Piston Complete 0.50mm - OEM Replacement Part

This complete piston assembly is a critical engine component for Multiquip rammers equipped with the Robin EC12 two-stroke gasoline engine. The 0.50mm oversize specification provides proper cylinder bore clearance for engines requiring rebore service, restoring compression and power output to factory specifications. In the MT-75H and MT-85H rammer series, this piston assembly works within the 6.96 cubic inch (114cc) air-cooled engine that produces 4.5 hp at 4,000 rpm, delivering 690 blows per minute with 2,865 lbs of impact force per blow.

The complete piston assembly includes all necessary components for proper installation during engine rebuild procedures. The Robin EC12 engine's two-stroke design requires precise piston-to-cylinder clearances to maintain optimal performance. Signs that piston replacement may be needed include loss of compression, excessive blow-by, hard starting, reduced power output, or the rammer failing to achieve its rated 4,000 rpm operating speed. When rebuilding the engine, proper break-in procedures should be followed after installation.

Compatible with the following Multiquip rammer models:

• MT-75H
• MT-85H
• MT75HS
