The Multiquip 374469820 Main Spring is a genuine OEM Main Spring designed for MT Series rammers. As a direct OEM replacement sourced through Multiquip's authorized parts program, this spring is built to the same specification as the original component that left the factory. Confirmed fitment for MT Series tampers makes part selection straightforward — match your model, order with confidence, and get your machine back to work.
Key Features
- Genuine OEM Spring Steel Construction — Manufactured to the same material and tension specification as the original, ensuring consistent stroke energy output on every cycle.
- Direct Drop-In Replacement — Engineered to seat and retain exactly as the factory spring does, with no modification to the rammer's lower mass or guide housing needed.
- MT Series Fitment Confirmed — Verified compatibility with Multiquip MT Series rammers, so you can order knowing this is the correct part for your machine.
- Sustained Impact Performance — A properly tensioned main spring delivers the consistent compaction force that keeps the rammer's jumping action effective in cohesive soils and trench work.
- Prevents Erratic Stroke Behavior — A fatigued or broken main spring causes weak, irregular strikes and can lead to secondary damage in the lower assembly; replacing it promptly restores full compaction output.
The main spring is the core energy-storage component in a rammer's compaction system. As the engine drives the piston upward, the spring compresses and then releases that stored energy downward through the lower mass, delivering the percussive force that compacts soil. When the main spring fatigues, loses tension, or breaks, the rammer loses striking power, develops an uneven jumping rhythm, and can place excess stress on surrounding lower-assembly components — making timely replacement essential to both performance and machine longevity.
