Multiquip 2742350107 Piston Ring Set EH09 - OEM Replacement Part for Tamping Rammers

This piston ring set maintains compression and engine performance in the Robin EH09 86cc air-cooled gasoline engine that powers Multiquip tamping rammers. The EH09 engine delivers 2.4 hp at 3,600 rpm and is designed to operate at 4,000 rpm for optimal performance, generating 690 impacts per minute with 2,250 lbs. of impact force per blow. Worn piston rings result in reduced compression, loss of power, increased oil consumption, and difficulty maintaining the factory-set operating speed required for proper clutch engagement and foot operation.

The Robin EH09 uses a fuel-lubrication oil spraying system and requires regular maintenance to sustain peak performance in demanding soil compaction applications. This genuine OEM piston ring set restores proper cylinder sealing and ensures the engine maintains sufficient power for the automatic centrifugal clutch system. Operating the rammer below full throttle due to compromised engine performance can damage clutch springs and the rammer foot.

Compatible with the following Multiquip tamping rammer models:

• MT54F
• MT55F
• MTR40F
