Overhaul Plate Kit for Twin Disc MG-514C

What this part is
A complete clutch pack refresh engineered for the Twin Disc MG-514C. The kit restores smooth, predictable engagement and consistent torque transfer by renewing the friction interface and stack geometry inside the MG-514C clutch assemblies.

What it includes

• Friction plates engineered to the MG-514C’s operating pressures and thermal loads.

• Assembly aids (where applicable) to stage, align, and index the stack during install.
  
  

What it fixes

• Slipping under load when engaging ahead/astern.
  
  

• Slow, harsh, or double-bump engagement due to worn friction surfaces or warped steels.
  
  

• Burnt-odor fluid, dark debris in oil, or glazing traces in the clutch carrier.
  
  

• Unpredictable boat handling during docking caused by inconsistent bite.
  
  

MG-514C fitment notes

• Specified for the MG-514C clutch design, control pressures, and case geometry.

MG-514C Troubleshooting by Symptom (Quick Catalog Guide)

Slipping on engagement — Start with Overhaul Plate Kit, then inspect Oil Filter Strainer, confirm control pressure and oil spec.
Repeat oil film or misting — Install Gasket & Seal Kit, verify case vents and surface finish.
Chatter or torsional vibration — Inspect Ring Drive, confirm bellhousing runout, review Rubber Blocks and alignment.
Low or erratic pressure — Service Oil Filter Strainer, verify pickup and screen, then reseal with Gasket & Seal Kit if needed.
Alignment won’t hold — Replace Rubber Blocks, realign, then re-evaluate coupling face/bore readings.

MG-514C Service Workflow (Best-Practice Sequence)

Baseline: Record oil level/condition, control pressure, case temperature, engagement feel, and noise/vibration notes.
Teardown plan: If clutch service is planned, pre-order the Overhaul Plate Kit, Gasket & Seal Kit, and Oil Filter Strainer to complete the job in one window.
Execution:

• Reseal disturbed covers/bores with the Gasket & Seal Kit.
  
  

• Install the Overhaul Plate Kit following stack order and pack height specs.
  
  

• Clean/replace the Oil Filter Strainer; refill with approved oil.
  
  

• Inspect Ring Drive and Rubber Blocks; correct any alignment contributors.
  Commissioning: Warm idle, neutral checks, light engagements both directions, then controlled harbor trial with post-run inspections.
  Documentation: Save clearances, torques, and pressure readings for future reference.
  
  

MG-514C Selection & Ordering Checklist

Identify the gear: Confirm MG-514C on the data plate (model and ratio).
Match symptoms to parts:

• Slipping/heat → Overhaul Plate Kit + strainer service.
  
  

• Weeping/aeration → Gasket & Seal Kit.
  
  

• Chatter/vibration → Ring Drive + Rubber Blocks + alignment check.
  
  

• Pressure alarms/debris → Oil Filter Strainer replacement/cleaning.
  Plan the window: Order all interdependent items together to minimize downtime.
  Aftercare: Early oil and strainer service after the first hours of operation.
