⚙️ Key Features

• Spring-loaded bearing-protector design maintains positive grease pressure
• Helps reduce water entry through the hub seal during launching and retrieval
• Suitable for routine greasing without removing the hub cap
• Supplied as a matched pair for one axle
• Marine-trailer service component

📏 Specifications

• Fitment: Heavy-duty LandCruiser/50–65mm axle hub family; confirm press-fit diameter
• Press-fit diameter must match the hub bore exactly
• Grease type must be compatible with the existing hub grease
• Do not over-pressurise the hub or force grease past the rear seal

🔄 Cross Reference & Related Parts

• Dunbier cross reference: 1781
• Standard-size Bearing Buddy pair: Mackay A1304 / Dunbier 1780
• PVC protector covers: Mackay A1307-2 / Dunbier 1782 where size matches

🚤 Compatibility & Application

• Compatible trailer hubs with the exact protector press-fit diameter
• Measure the hub bore rather than relying only on axle size

• Inspect and service wheel bearings independently; a protector does not repair damaged bearings

🔌 Function

⚠️ Common Signs of Failure

• Protector is loose in the hub bore
• Spring piston is seized or will not accept grease
• Grease or water leaks around the protector
• Cover is missing and contamination builds around the piston
• Hub continues to take excessive grease because the rear seal has failed
