Twin Disc MG5114A Marine Transmission Parts – Gasket and Seal Kit Section

The Twin Disc MG5114A Gasket and Seal Kit (Angled Drive) is the complete sealing package designed specifically for the angled-drive configuration of the MG5114A marine transmission. This model is commonly found in vessels where space and alignment require the propeller shaft to be offset at an angle from the engine. The angled drive design introduces additional stress points and temperature variations that can accelerate gasket and seal wear. This precision-engineered kit restores full sealing integrity throughout the transmission, preventing fluid leaks, maintaining hydraulic pressure, and protecting internal clutch and gear components from contamination.

Twin Disc Gasket and Seal Kit for Marine Gear MG5114A – Angled Drive

This high-quality kit includes:

• Gaskets for all major case joints, inspection covers, and end housings
  
  

• Oil seals for both input and output shafts designed to maintain pressure at angled interfaces
  
  

• O-rings, compression washers, and sealing rings for hydraulic passages
  
  

• Drain plug and filler cap seals for complete leak prevention
  
  

Each gasket and seal is manufactured from marine-grade materials that resist degradation from heat, oil, and saltwater exposure. These components are precision-matched for the MG5114A’s unique angled-drive geometry, ensuring a perfect fit and long-lasting sealing performance even under heavy propulsion loads.

Signs You May Need This Kit

• Oil leaks appearing around the angled housing or output shaft area
  
  

• Fluctuating oil pressure or delayed clutch response
  
  

• Visible residue or film near gaskets or inspection covers
  
  

• Increased operating noise or slipping under load due to hydraulic pressure loss
  
  

Replacing the gasket and seal kit restores complete containment, eliminates leaks, and protects against costly damage caused by oil starvation or contamination. It is one of the most effective ways to extend the operational life of the MG5114A marine gear.
