Twin Disc MG5091 Marine Transmission – Gasket and Seal Kit
The Gasket and Seal Kit for the Twin Disc MG5091 marine transmission provides everything needed to restore full sealing integrity and prevent oil leaks in the shallow case version of this gear. Each kit includes all major gaskets, O-rings, and sealing components used throughout the unit—from clutch housings to input and output covers. When servicing an MG5091, replacing these seals ensures that hydraulic pressure remains consistent and internal lubrication is properly contained, reducing the risk of clutch slippage, fluid loss, or overheating.
Typical signs that your MG5091 may require a reseal include oil drips beneath the transmission, slow clutch engagement, or visible gasket deterioration during inspection. Because the MG5091 operates in continuous-duty marine environments, seals can harden and lose elasticity over time. Installing a complete gasket and seal kit restores original performance, prevents costly fluid leaks, and helps extend the life of your transmission. All components are designed to meet or exceed OEM sealing standards for fit and durability.
All MG5091 gasket and seal kits are in stock and ready to ship directly from Diesel Pro Power, trusted by over 40,000 satisfied customers worldwide for genuine parts, fast delivery, and unmatched support for Twin Disc marine gears.
Twin Disc MG5091 Marine Transmission – Rubber Blocks (26 Required)
The rubber blocks used on the Twin Disc MG5091 marine transmission are essential vibration-dampening components that help stabilize the gear assembly and reduce stress on the housing and mounts. The MG5091 requires 26 individual rubber blocks, each serving as a flexible cushion between the clutch plates and drive components. These blocks absorb the torsional vibration created during gear shifts and torque transfer, ensuring smoother operation and protecting against premature wear in both the clutch pack and transmission casing.
Over time, these rubber blocks can harden, crack, or compress unevenly due to heat and constant load cycles. Replacing all 26 blocks during overhaul or service keeps clutch engagement consistent and helps prevent mechanical chatter or noise under heavy load. Properly maintained rubber blocks also reduce transmission vibration transmitted through the hull, improving overall vessel comfort and mechanical stability.
All MG5091 rubber blocks are stocked and available for immediate shipment from Diesel Pro Power, ensuring technicians and operators can complete maintenance without delay and keep their marine gears performing smoothly and reliably.
