Neptun Trailer maintenance

From new (2015), the left side wheel of the trailer when hitched, sitting in the car, had a bit of play. A friend had a hub fail when towing last November, which pushed me into a rush inspection today.

A castellated nut and 3.6 x 36mm cotter pin fit on a taper bearing.  The cover tapped off quite easily and snapped back with a tap. The nut was loose, so for completeness I removed the taper bearing and hub. No marks. Plenty of clean grease. Nut went back on with the original pin at 12 o/c. No play, and the nut wasn't loose enough to turn with fingers before being pinned.
Leaving the wheel on the hub was probably a mistake as it made the assembly heavy when re-assembling. Best to do the job on the ground.

Taper bearing and washer removed and put back in axle
