The Multiquip 303010270 Main Spring A B is a genuine OEM component designed for the MTR55 trench rammer. Sourced directly from Multiquip, this spring meets the exact specifications required for proper operation of the MTR55 ramming mechanism. If you're servicing or rebuilding your trench rammer, using the correct OEM spring ensures the machine performs as intended from the moment it's put back to work.
Key Features
- Genuine OEM Spring Steel Grade — Manufactured to Multiquip's original material and tension specifications, ensuring the spring delivers the correct force output for the MTR55 ramming cycle.
- Direct Drop-In Replacement — Engineered to seat and connect exactly as the original, with no fitting adjustments or modifications needed during installation.
- Built for MTR55 Trench Rammers — Confirmed fitment for the MTR55, Multiquip's dedicated trench rammer platform designed for work in confined trenching applications.
- Maintains Consistent Impact Energy — A correctly tensioned main spring sustains the rhythmic impact stroke that gives the rammer its compaction power; a worn or broken spring leads to weak, inconsistent blows or complete loss of ramming action.
- Authorized Multiquip OEM Part — Sold by DHS Equipment as an authorized Multiquip parts distributor, so you receive the exact part intended for this machine.
The main spring is the core energy-storage component in a trench rammer's reciprocating drive system. As the engine drives the mechanism, the spring compresses and releases in rapid succession, generating the downward impact force that compacts soil in trenches and tight spaces. When the main spring weakens, cracks, or breaks entirely, the rammer loses striking force, produces uneven compaction, or stops cycling altogether — making timely replacement critical to keeping compaction work on schedule.
