Twin Disc MG514C Marine Transmission Parts – Oil Pump & Filter Section

The Twin Disc MG514C oil and hydraulic system is a vital part of the transmission’s performance, ensuring steady pressure, clean lubrication, and consistent clutch operation under heavy marine loads. Over time, oil pumps, filters, gaskets, and breathers are subject to wear, heat stress, and contamination that can lead to leaks, reduced oil flow, or pressure loss. This section provides all the essential components for restoring the MG514C’s hydraulic and lubrication system to peak condition—helping prevent clutch slippage, overheating, and costly downtime.

Twin Disc Hydraulic Pump for MG514C Marine Transmission

The hydraulic pump is the heart of the MG514C’s oil system. It generates the pressure needed for clutch actuation and internal lubrication, circulating fluid through the system to maintain consistent operation across a wide range of engine speeds. This new, OEM-grade pump is built to factory specifications for precise flow and long-term durability in saltwater environments.

Key Features:

• Precision-machined housing for efficient oil flow and quiet operation
  
  

• Designed for high-pressure marine transmission systems
  
  

• Corrosion-resistant materials for extended life in harsh conditions
  
  

• Direct bolt-on replacement for the MG514C transmission—no modification required
  
  

When to Replace the Hydraulic Pump:

• Loss of oil pressure or erratic gauge readings
  
  

• Slipping clutches or slow engagement under load
  
  

• Audible whine or vibration from the pump housing
  
  

• Evidence of metal shavings or debris in transmission oil
  
  

Replacing the hydraulic pump restores consistent oil pressure and proper clutch response—critical for smooth propulsion performance.

Twin Disc Oil Pump Gasket for MG514C

The oil pump gasket forms a tight seal between the pump and the transmission casing. It prevents oil leaks and ensures that full system pressure is maintained throughout the lubrication circuit. Over time, gaskets can compress, harden, or crack due to heat cycling and constant exposure to oil.

Key Features:

• Oil- and heat-resistant composite material for reliable long-term sealing
  
  

• Maintains proper hydraulic pressure within the MG514C housing
  
  

• Prevents external leakage and internal pressure loss
  
  

• Simple, precise fit for quick replacement during service
  
  

Always replace the gasket when installing a new pump or servicing the oil system to prevent pressure loss and maintain maximum efficiency.

Twin Disc Oil Filter Gasket for MG514C

The oil filter gasket ensures a secure seal between the filter assembly and the transmission housing, preventing leaks during operation. A worn gasket can cause oil seepage, leading to reduced pressure and contamination of internal components.

Benefits:

• Provides a tight, oil-proof seal at the filter base
  
  

• Made from durable material designed for high-pressure systems
  
  

• Easy to replace during routine oil filter maintenance
  
  

A clean filter and fresh gasket help maintain stable oil pressure and protect the MG514C’s clutch components and gears from debris and abrasion.

Breather for Twin Disc MG514C Marine Transmission

The breather plays an important role in managing pressure changes within the transmission housing. As oil heats and cools, air expansion and contraction occur—this breather allows controlled ventilation, preventing pressure buildup while keeping out dirt and moisture.

Key Benefits:

• Regulates internal air pressure for consistent system balance
  
  

• Prevents seal damage caused by overpressure
  
  

• Keeps contaminants such as dust, salt, and water from entering the gearbox
  
  

• Made from corrosion-resistant materials suitable for marine use
  
  

If you notice oil residue near the breather or signs of pressure imbalance, replacement is recommended to protect the seals and internal gaskets.

Twin Disc Oil Filter Strainer for MG514C

The oil filter strainer is the primary filtration component, responsible for trapping contaminants before they circulate through the clutch and bearing assemblies. Clean oil ensures consistent clutch engagement, smooth operation, and reduced wear.

Features:

• Fine-mesh screen captures metal particles and sludge
  
  

• Durable marine-grade construction
  
  

• Maintains steady oil flow and hydraulic pressure
  
  

• Easy to remove and clean during routine servicing
  
  

When to Replace or Clean the Strainer:

• Drop in oil pressure or temperature rise in the transmission
  
  

• Dirty or discolored transmission oil
  
  

• Slow clutch engagement or increased vibration during operation
  
  

Keeping the strainer clean and functional ensures reliable lubrication across all internal components.

Twin Disc Secondary Oil Filter Strainer for MG514C

The secondary oil strainer provides an additional level of filtration within the MG514C system. This filter captures residual particles that may bypass the main filter during high-flow conditions, adding another layer of protection for the hydraulic pump and clutch assemblies.

Benefits:

• Enhances oil cleanliness and prevents circulation of contaminants
  
  

• Prolongs the life of pumps, seals, and internal moving parts
  
  

• Easy installation with direct-fit design for the MG514C
  
  

• Recommended for use during full transmission overhauls or fluid changes
  
  

Importance of Regular Oil System Maintenance

In the MG514C, clean and properly pressurized oil is essential for consistent clutch engagement and long service life. A failing pump, clogged filter, or damaged gasket can lead to pressure loss, clutch overheating, and mechanical wear. Routine maintenance—replacing pumps, filters, and gaskets—protects your investment and keeps the transmission operating smoothly under the toughest marine conditions.
