Overhaul Plate Kit for Twin Disc MG-516
What this part is
A complete clutch-pack refresh engineered specifically for the Twin Disc MG-516. It restores clean, predictable engagement and dependable torque transfer by renewing the friction interface and steel mating surfaces inside the MG-516 clutch assemblies.
What it includes
-
Friction plates matched to MG-516 control pressures and thermal loads.
-
Steel separator plates precision-ground for flatness and parallelism to prevent hot spots.
-
Setup guidance to achieve the correct clutch pack height and stack order.
-
Assembly aids (where applicable) to streamline staging, indexing, and pre-lube.
What it fixes
-
Slipping under load when shifting ahead or astern.
-
Harsh, delayed, or double-bump engagement from worn or glazed plates.
-
Burnt odor or dark debris in oil indicating overheated clutches.
-
Inconsistent maneuvering control in docking or tight quarters.
Signs you likely need this kit
-
RPM flares without proportional vessel movement on engagement.
-
Shudder on pickup or “grab–release–grab” at low throttle.
-
Elevated gearbox temperature after frequent maneuvering.
-
Metallic or fibrous residue caught in the strainer soon after service.
Installation highlights
-
Measure as-found pack height before teardown; document counts and clearances.
-
Dry-stage the stack to verify order and quantity; then pre-lube all plates.
-
Check steels for warp or bluing; replace as needed.
-
Torque carrier hardware to spec in a cross pattern; verify runout.
-
Warm no-load run-in, followed by progressive load checks; recheck oil and for leaks.
Why buy this MG-516 overhaul kit from Diesel Pro Power
-
MG-516–specific curation ensures plate materials and steel thicknesses align with MG-516 control pressures and target pack height.
-
Technician-first documentation helps your crew hit stack height quickly and consistently.
-
System thinking: paired guidance with seals, filtration, and mounts to prevent rework.
Gasket & Seal Kit for Twin Disc MG-516
What this part is
A complete reseal solution tailored to the MG-516 case, covers, shafts, and service ports. It eliminates weeping, stabilizes hydraulic pressure, and protects fresh clutch work from contamination.
What it includes
-
Form-fit case and cover gaskets for MG-516 inspection and service plates.
-
Lip seals and O-rings for input/output shafts and control interfaces.
-
Crush washers (where applicable) for ports and plugs to ensure proper seating.
What it fixes
-
Chronic oil film or misting around covers and perimeters.
-
Aeration/foaming due to air ingress at tired seals.
-
Control pressure instability from internal leakage paths.
-
Messy bilge and contamination risks that shorten clutch life.
Signs you likely need this kit
-
Repeat top-offs with no obvious drips, suggesting seepage.
-
Dampness at selector cover, inspection plates, or shaft exits.
-
Fresh oil smears returning shortly after sea trials.
Installation highlights
-
Thoroughly clean mating faces; avoid gouging aluminum surfaces.
-
Lightly oil seal lips and use guide sleeves over splines to prevent nicks.
-
Seat and torque port fittings on clean, burr-free faces; confirm crush washer conformity.
-
Run test and reinspect perimeters and rotating shafts for early leak detection.
Why buy this MG-516 gasket & seal kit from Diesel Pro Power
-
Exact MG-516 profiles and diameters reduce fitment guesswork.
-
Marine-ready elastomers chosen for MG-516 temperature and oil chemistry.
-
One-and-done reseal bundles help you finish in a single maintenance window.
Rubber Block (Mount Isolator) for Twin Disc MG-516 Installations
What this part is
A vibration-damping isolator that supports and stabilizes the MG-516 and adjacent drivetrain components. Correct isolation reduces shock transfer to the hull, protects seals and bearings, and helps alignment hold over time.
What it includes
-
Marine-grade elastomer element designed for combined compression and shear loads.
-
Bonded/captured interfaces (design varies) for secure mounting and repeatable preload.
What it fixes
-
Persistent vibration at cruise or certain RPM bands.
-
Alignment drift that returns after seemingly perfect shaft alignment.
-
Premature wear on couplings, seals, and bearings from rigid mounting.
-
Structure-borne noise traveling through stringers or hull frames.
Signs you likely need this part
-
Compression set, cracks, or delamination visible on existing mounts.
-
Noticeable bump/knock when shifting from neutral into gear.
-
Vibration worsens under load but eases off-throttle.
Installation highlights
-
Replace in matched sets to maintain equal support height and stiffness.
-
Re-align engine and gear after mount work; verify coupling face and bore readings.
-
Re-torque after initial operating hours as the elastomer settles.
Why buy these MG-516 mounts from Diesel Pro Power
-
Load-rated options selected for MG-516 support geometry and thrust reactions.
-
Alignment-centered guidance helps protect new seals and clutches from vibration-related damage.
-
Convenient pairing with overhaul and reseal items to minimize downtime.
MG-516 Symptom-to-Parts Quick Guide
Slipping or delayed engagement — Start with the Overhaul Plate Kit, then service the oil strainer and verify control pressure.
Recurring oil film or misting — Install the Gasket & Seal Kit; check vents and mating surfaces.
Chatter or driveline vibration — Replace Rubber Blocks, confirm alignment; inspect coupling condition.
Low/erratic pressure alarms — Clean/replace the oil strainer (and reseal if needed) to stabilize flow.
Alignment won’t hold — New Rubber Blocks, re-shim, and re-verify coupling face/bore readings.
MG-516 Selection & Ordering Checklist
Confirm the gear: Verify MG-516 on the data plate (model and ratio).
Match symptoms to parts:
-
Slipping/heat → Overhaul Plate Kit + strainer service.
-
Weeping/aeration → Gasket & Seal Kit.
-
Vibration/chatter → Rubber Blocks + alignment check.
-
Pressure alarms/debris → Oil strainer cleaning or replacement.
Stage everything together: Order interdependent items as a bundle to minimize repeat haul-outs.
Aftercare: Early oil and strainer service after initial operating hours post-repair.
