Multiquip 305446420 Spring Main MTR-35W - OEM Replacement Part

The main spring is a critical component in Multiquip truss-style rammers, providing the essential rebound force that enables the machine's high-frequency compaction action. This spring works in conjunction with the ramming mechanism to deliver the MTR-35W's rated 1,210 lbs. of impact force per blow at 720-750 blows per minute. Spring failure or fatigue will result in reduced compaction efficiency, abnormal vibration, or complete loss of ramming action.

A worn or broken main spring compromises the rammer's ability to maintain its specified impact force and operating frequency, directly affecting compaction quality and productivity. Regular inspection of the main spring for cracks, deformation, or loss of tension is essential during routine maintenance intervals. This genuine OEM spring is manufactured to Multiquip's exact specifications to ensure proper fit, durability, and performance restoration.

Compatible with the following Multiquip rammer models:

• MTR-35HS
• MTR-35W
• MTR-40HS
• MTR40F
• MTR40HF
