Multiquip 355447270 Spring Main MT-75H - OEM Replacement Part for Tamping Rammers

The main spring is a critical component in Multiquip tamping rammers that converts the circular motion from the engine into the powerful vertical impact force needed for soil compaction. This spring operates within the spring cylinder assembly and works in conjunction with the oil bath lubrication system to deliver consistent, high-force impacts to the rammer foot during operation.

In the MT series rammers, the main spring is part of the gearbox and spring cylinder assembly that enables the unit to apply tremendous consecutive impacts to soil surfaces. The spring system is essential for leveling and uniformly compacting voids between soil particles to increase dry density in applications including road construction, embankments, reservoir work, and backfilling for gas pipelines, water pipelines, and cable installation projects. Regular inspection of the spring cylinder assembly should be performed when checking the oil level through the oil level sight glass at the rear of the tamper foot.

This main spring is compatible with the following Multiquip tamping rammer models:

• MT-74F
• MT-74FA
• MT-75H
• MT-84F
• MT-84FA
• MT74FAF
• MT75HS
