Twin Disc MG 516 Marine Transmission Parts for Australia - Gasket and Seal Kit Section

Twin Disc MG516 Marine Transmission Parts – Gasket and Seal Kit Section

The Twin Disc MG516 marine transmission is a heavy-duty workhorse found in commercial vessels, tugboats, ferries, and offshore service boats. Its dependability depends on precision sealing—keeping oil where it belongs and preventing air or water intrusion that can compromise hydraulic pressure and clutch engagement. Over time, seals can harden, gaskets can flatten, and minor leaks can develop into costly failures. The Twin Disc MG516 Gasket and Seal Kit is engineered to restore tight, factory-level sealing integrity throughout your gear assembly, ensuring smooth operation and long-term reliability.

Twin Disc Gasket and Seal Kit for MG516

This complete gasket and seal kit includes all the critical soft components used during an MG516 service or rebuild. The set covers all major sealing points within the clutch housing, hydraulic valve body, input and output shafts, inspection covers, and cooler line ports. Each gasket is made from premium-grade materials compatible with marine transmission oil, while the O-rings and seals are molded from heat- and pressure-resistant elastomers to handle continuous operation in demanding marine conditions.

You’ll want to replace these components if you notice oil leaks near the shaft seals, drips forming under the gear housing, or pressure loss on the hydraulic gauge. Other signs include soft or delayed engagement, foamy transmission oil, or visible cracks and brittleness in existing seals. Resealing your MG516 with this kit not only restores performance but also protects internal bearings, clutch packs, and hydraulic passages from contamination and fluid loss.

Designed for both straight and deep case configurations, this kit ensures perfect alignment and sealing without modification. It eliminates the need to track down individual gaskets or measure generic substitutes—everything needed for a professional reseal is included in one package, making it ideal for both shipyard maintenance teams and individual operators.

Rubber Block for Twin Disc Marine Gears

Also featured in this section is the rubber block, a vibration-absorbing isolator used across multiple Twin Disc marine gear models, including the MG516. This durable component cushions the transmission from engine torque fluctuations and propeller thrust loads. It helps maintain alignment and prevents harmful vibrations that can lead to fatigue cracks, seal distortion, or bearing wear.

Aging rubber blocks can harden, crack, or lose elasticity, increasing vibration and contributing to leaks. Replacing them during gasket and seal service ensures smoother operation and extends the lifespan of the transmission. Diesel Pro Power’s rubber blocks are made from premium marine-grade elastomers designed to resist oil, saltwater, and temperature extremes.
