Twin Disc MG521 Marine Transmission Parts – Rubber Block Section

The Twin Disc MG521 rubber block is an essential vibration-dampening component designed to protect your marine transmission and driveline system. Each MG521 transmission requires 26 rubber blocks for proper installation and balanced performance. These blocks work together to absorb vibration, cushion torque transfer, and prevent shock loads from reaching critical internal components such as bearings, clutches, and seals.

Engineered specifically for the MG521 marine transmission, these rubber blocks are made from high-strength, oil- and heat-resistant marine-grade rubber. They provide consistent flexibility and durability under the demanding conditions of continuous-duty marine operation. By isolating engine vibration, they reduce structural stress, minimize noise, and enhance comfort on board—important benefits for both commercial and private vessels.

Over time, rubber components naturally wear, harden, or lose elasticity due to exposure to oil, heat, and constant torque loading. Replacing all 26 rubber blocks during scheduled service or when performing transmission maintenance ensures even support and proper alignment. This helps maintain smooth operation, prolong the lifespan of your MG521 transmission, and prevent costly mechanical failures caused by vibration or misalignment.
