Twin Disc MG5111A Marine Transmission Parts – Gasket and Seal Kit Section

The Twin Disc MG5111A Gasket and Seal Kit (Angled Drive) is a precision-engineered reseal package designed specifically for the angled-drive configuration of the MG5111A marine transmission. Built to withstand demanding marine environments, this kit restores complete sealing integrity throughout the transmission’s hydraulic and mechanical systems. Over time, seals, gaskets, and O-rings within the MG5111A harden and compress under constant heat, pressure, and oil exposure. This kit replaces every critical sealing component, helping eliminate leaks, maintain hydraulic pressure, and extend the life of your marine gear.

Twin Disc Gasket and Seal Kit for Marine Gear MG5111A – Angled Drive

This comprehensive kit includes:

• Gaskets for all major housing and cover interfaces specific to the angled-drive version
  
  

• Input and output shaft oil seals engineered for marine-grade resistance
  
  

• O-rings and compression washers for control housings and internal channels
  
  

• Drain plug and filler seals for complete containment protection
  
  

Each piece is manufactured to exact OEM-grade tolerances, ensuring a tight fit and long-lasting reliability. The kit supports the unique geometry and lubrication pathways of the angled MG5111A drive assembly, ensuring complete sealing even under heavy propulsion load.

Signs You May Need This Kit

• Transmission oil leaks around the drive angle housing or shaft seals
  
  

• Hydraulic pressure loss resulting in delayed or inconsistent clutch engagement
  
  

• Oil residue around inspection covers, filter housings, or gear joints

Replacing the gasket and seal kit during overhaul or scheduled service prevents performance loss, protects internal components, and restores smooth, efficient power transfer between the engine and propeller shaft.
