MG 507 Twin Disc Marine Transmission Parts for Canada - Oil Pump Section

Twin Disc MG507 Marine Transmission Parts – Oil Pump Section

The Twin Disc MG507 oil pump assembly plays a central role in maintaining hydraulic pressure and proper lubrication inside the transmission. Designed specifically for the MG507, MG507-1, and MG507A marine gears, this heavy-duty oil pump ensures smooth clutch operation, even oil flow to all internal components, and reliable performance under continuous load. Because the MG507 operates in demanding marine environments, with constant temperature fluctuations and high torque transfer, keeping the oil pump in optimal condition is essential to avoid clutch slippage, overheating, or gear wear.

Twin Disc Oil Pump for Marine Gear MG507, MG507-1 & MG507A

The Twin Disc oil pump is a precision-engineered, gear-driven unit that delivers consistent oil pressure to lubricate bearings, clutch plates, and valve assemblies while circulating transmission fluid through the system. Without a properly functioning pump, the MG507 cannot maintain the hydraulic force required for proper clutch engagement.

Key Features:

• High-flow gear design optimized for MG507-series transmissions
  
  

• Built from corrosion-resistant marine-grade metals to withstand saltwater environments
  
  

• Delivers consistent oil pressure across all speed and load conditions
  
  

• Restores factory hydraulic performance and lubrication balance
  
  

• Direct replacement—no modifications or adjustments needed
  
  

When to Replace the Oil Pump:

• Transmission oil pressure is low or fluctuating
  
  

• Clutch engagement becomes delayed or inconsistent
  
  

• Transmission oil appears dark, aerated, or contains metal particles
  
  

• Unusual whining or grinding noise from the pump area
  
  

Replacing the oil pump ensures the MG507 operates with full hydraulic pressure, preventing clutch slip, heat buildup, and internal wear—common issues in older or high-hour transmissions.

Twin Disc Oil Pump Gasket for MG507

The oil pump gasket provides the critical seal between the pump body and transmission housing. Even a small oil leak at this joint can reduce system pressure and cause loss of hydraulic control, leading to shifting problems or overheating.

Key Features:

• Constructed from oil- and heat-resistant composite material
  
  

• Designed to maintain proper compression and sealing under constant vibration
  
  

• Prevents external leaks and internal pressure loss
  
  

• Compatible with MG502, MG506, and MG507 (new-style configurations)
  
  

When to Replace the Oil Pump Gasket:

• Any time the pump is serviced or replaced
  
  

• Signs of oil seepage or residue near the pump flange
  
  

• Old gasket has hardened, cracked, or flattened from years of use
  
  

Replacing the gasket during oil pump installation ensures the entire hydraulic circuit remains sealed, maintaining clean and efficient fluid circulation within the MG507.

Importance of Proper Lubrication in the MG507

The MG507’s clutch packs, bearings, and planetary gears rely on consistent oil flow to stay cool and prevent premature wear. When the oil pump or gasket fails, hydraulic pressure drops and oil circulation slows, allowing heat to build up and friction materials to deteriorate. Regular inspection and timely replacement of the pump and sealing components are critical steps in preventing costly transmission failure.
