Twin Disc MG-514B Marine Transmission Parts — Overhaul Plate Kit Section

This catalog presents a streamlined list of MG-514B overhaul and service components so you can build an accurate parts order fast. It highlights the overhaul plate kit and the core supporting items—gasket & seal kit, oil filter, ring drive (SAE #1), and rubber block—with concise fitment notes, selection cues, and common use cases specific to the MG-514B.

Overhaul Plate Kit — MG-514B

Purpose: Complete friction/steel refresh for the MG-514B clutch pack.
Includes: Friction plates, steel separator plates, and select retainers/shims/snap rings (when packaged by kit).
Fitment: MG-514B only.
Results: Restores stack height, improves engagement consistency, reduces heat/glazing.
Notes: Verify nameplate, reduction ratio, and case style (shallow/deep) to confirm plate count and thickness.

Gasket & Seal Kit — MG-514B

Purpose: Reseal components disturbed during clutch service.
Includes: Case gaskets, inspection cover seals, input/output shaft seals, O-rings for hydraulic unions/strainers.
Fitment: MG-514B only.
Results: Shorter fill times, stable hold pressure, reduced seepage.

Oil Filter — MG-514B

Purpose: Protect valves, pistons, and clutch surfaces from wear debris.
Spec Highlights: MG-514B-specific media and bypass setting for consistent apply timing.
Use: Replace at commissioning after plate installation; follow with an early change to remove break-in fines.
Fitment: MG-514B only.

Ring Drive — SAE #1 (MG-514B)

Purpose: Maintains concentricity between engine flywheel housing and MG-514B input coupling.
Fitment: SAE #1 housing; MG-514B only.
Inspection Cues: Heat spotting, cracked lands, elongated bolt holes, coupling spline wear.
When to Add: High hours, vibration history, or heat-distressed plates.

Rubber Block — MG-514B

Purpose: Torsional isolation/shock damping during clutch apply.
Fitment: MG-514B only.
Replace If: Cracked, glazed, oil-soaked, compressed, or if direction changes produce a “thud.”
Benefit: Smoother take-up, reduced chatter, lower seal/bearing shock.

Quick Selection Guide (MG-514B)

• Clutch slipping / heat discoloration: Overhaul Plate Kit + Oil Filter
  
  

• Slippage + minor leaks/weeping: Overhaul Plate Kit + Gasket & Seal Kit + Oil Filter
  
  

• High hours + vibration complaints: Overhaul Plate Kit + Gasket & Seal Kit + Rubber Block; evaluate Ring Drive
  
  

• Post-service filtration plan: New Oil Filter at commissioning + early follow-up change
  
  

Fitment & Identification (MG-514B)

• Model: Confirm “MG-514B” on the gear nameplate.
  
  

• Ratio / Case Style: Record reduction ratio and shallow/deep case for correct plate count and gasket profiles.
  
  

• Environment: If prior overheating or coupling wear is present, add Ring Drive and Rubber Block to the parts list.
