Short Description: Ensure the longevity and smooth rotation of your wheels with this high-quality Hub Bearing Bushing and Dust Seal. This essential component protects your hub from road grime and contaminants, preventing premature bearing failure and restoring the ride quality of your Dnepr MT-11.

Technical Specifications:

• Compatibility: Dnepr MT-11 (and compatible models)
• Manufacturer Code / SKU: 7204142, 7205246-a
• Part Type: Running Gear / Wheel Assembly

Purpose and Role in the Motorcycle (based on the original manual):
The wheel hubs of the Dnepr MT-11 utilize adjustable tapered roller bearings (type 6-7204A) to handle the significant loads of a heavy-duty motorcycle and sidecar combination. This bushing and dust seal assembly acts as the "labyrinth packing" described in the technical manual, situated at the critical joint between the wheel and the brake drum. Its primary role is to create a physical barrier that prevents the direct ingress of dust, water, and road debris into the bearing races. Without a functional seal, contaminants mix with the hub lubricant, leading to abrasive wear, audible grinding noises, and eventual bearing seizure. A need for replacement is typically indicated during the scheduled 20,000–40,000 km maintenance interval, or if you notice excessive heat emanating from the wheel hub after a short ride.

Benefits of Buying:

• Exact Technical Fit: Engineered to match the original factory specifications of the MT-11 hub, ensuring a seamless install without modifications.
• Enhanced Component Lifespan: By effectively sealing out contaminants, this part significantly extends the service life of your expensive tapered roller bearings.
• Improved Safety and Stability: Eliminates the risk of bearing play and overheating, ensuring the motorcycle maintains a steady trajectory and reliable wheel rotation under maximum load.
