🚤 Trailer Compatibility & Application

• Not a universal plate for AL-KO, Fulton or generic top-wind jockey wheels
• Check the shaft, gears, roll pins and housing before deciding to replace the plate alone

🔌 Function

Retains the internal bevel gears in their correct operating position so handle rotation is transferred smoothly to the lifting screw.

⚠️ Common Signs of Failure

• Metal fragments or excessive play are present inside the top housing
• Retaining plate no longer seats firmly in the gearbox

🛠️ Installation & Safety

• Unload and safely support the trailer before dismantling the jockey wheel
• Record gear and washer orientation during disassembly
• Clean and inspect the screw, shaft and gear teeth before reassembly
• Lubricate the internal gearing with a suitable water-resistant grease
• Replace damaged gears and retaining pins rather than fitting the plate to a worn assembly
