The Twin Disc MG5114 and MG5114SC Gasket and Seal Kit is a complete sealing solution specifically designed for shallow-case MG5114 marine transmissions with gear ratios ranging from .93:1 to 3:1. This kit restores full sealing integrity across all major interfaces of the gearbox, preventing oil leaks, maintaining hydraulic pressure, and ensuring optimal clutch performance. Whether you operate a commercial vessel, fishing boat, or recreational craft, maintaining tight seals within your MG5114 transmission is essential for reliable propulsion and long-term performance.
Twin Disc Gasket and Seal Kit for Marine Gear MG5114 & MG5114SC
This precision-engineered kit includes:
-
All main housing and inspection cover gaskets
-
Front and rear shaft oil seals for input and output housings
-
O-rings and sealing washers for hydraulic passages and control ports
-
Drain plug and filler cap seals for complete containment protection
Each component is built from marine-grade materials that resist heat, oil breakdown, and saltwater corrosion. When installed during routine service or rebuild, this kit prevents fluid seepage, protects against pressure loss, and supports consistent clutch engagement across all gear ratios.
Signs You May Need This Kit
-
Visible oil seepage near clutch housings, flanges, or drain plugs
-
Drops in hydraulic oil pressure or delayed clutch engagement
-
Residue or leakage around inspection covers or oil lines
-
Reduced transmission performance or shifting irregularities
Replacing worn seals and gaskets as part of your scheduled maintenance prevents larger issues such as clutch slippage, overheating, or gear damage—especially under heavy marine load conditions.
Why Install a New Gasket and Seal Kit
The MG5114’s shallow case design requires tight sealing to maintain oil pressure balance. Even minor leaks can lead to clutch fade or inconsistent torque transfer. Installing a fresh gasket and seal kit ensures that all internal oil passages remain sealed, helping your gearbox maintain steady hydraulic pressure and protecting against contamination.
