Orion Motor Tech Truck Hub Seal Installer Kit — Class 7-8, Aluminum Drivers (5 Sizes)

If you service heavy-duty trucks, the right seal installer saves time and protects expensive bearings and seals. This kit from Orion Motor Tech includes multiple driver sizes, extension handles, and a blow-molded case to help technicians and fleet mechanics fit hub seals accurately, reduce misalignment, and avoid repeat disassembly. The tools are forged from corrosion-resistant aluminum for durable, non-marring contact with seals and races.

How does this kit speed up hub seal installation?

The kit is designed so you can press seals and races straight into position from outside the hub, often eliminating the need to remove brake drums. Multiple driver diameters and two extension handles let you reach deep-set seals and maintain even force distribution, reducing hammering and rework.

• Five driver sizes to match common seal/race diameters on Class 7–8 hubs
• Two extension handles for extra reach and leverage
• Aluminum drivers that minimize marring and bounce
• Blow-molded case keeps parts organized for quick job starts

Will this kit fit my truck model and bearings?

The OMT installer kit covers a wide range of heavy-duty trucks, including most over-the-road Class 7 and Class 8 models, trailers, and some medium-duty vehicles. It’s intended for typical hub seal and bearing race sizes used on those axles, but verifying your hub dimensions before purchase ensures the best match.

• Compatible with popular Class 7 & 8 hub sizes
• Works on many trailer and medium-duty applications
• Check hub inner diameter against driver sizes for fit confirmation
• Useful for fleet maintenance and roadside service calls

What materials and construction features matter for longevity?

These installers are machined from high-quality aluminum to resist corrosion and reduce weight without sacrificing strength. Aluminum drivers transfer impact force evenly and are less likely than steel to damage sealing surfaces; the included case protects tools from the shop environment and simplifies transport.

• Durable aluminum drivers for corrosion resistance
• Non-marring contact reduces risk to seals and races
• Blow-molded plastic case for organized storage and protection
• Compact, lightweight set for mobile mechanics and shops

How do I use the kit safely and effectively?

Match the driver diameter to the seal or race surface, assemble an extension if needed, and apply steady, controlled impacts with a dead-blow or soft-faced hammer to seat the component. Avoid angled strikes; keeping the driver square to the hub ensures correct seating and prevents distortion.

• Select driver matching the outer lip or race surface
• Use extension handles for deeper hubs or extra reach
• Tap evenly with a soft-faced hammer to prevent damage
• Confirm proper seating by visual and tactile inspection

Who is this for: The OMT Truck Hub Seal Installer Kit is aimed at heavy-duty truck technicians, fleet maintenance crews, mobile mechanics, and anyone who regularly services Class 7 and Class 8 axles. It’s particularly useful where speed, repeatable results, and protecting bearings and seals matter—such as fleet garages, service vans, and roadside repair teams.
