We have a 2004 Kimberley Kamper

Hello, both my wheels have holes thru the handle where a pin goes and fixes it to
the threaded rod, maybe you've lost the pin. Or the handle may have a grub screw missing.

Jockey wheels are cheap.

I had the same thing happen on my 2003 Kimberley kamper. If you have the same jockey wheel as mine had, the handle is held on by a grub screw with an allen key head.

If you look at the internal rod it will have a recess that the grub screw goes into. The handle should have a hole that the screw goes in.

Thanks for that info. Sounds like it could be. Will have a further look tomorrow.

Jockey wheels seem to be consumables theses days.

As stated the handle is usually held in place by either a grub screw or a hardened steel 'spring pin' called a Roll Pin. Both items would cost about one dollar. If yours uses a roll pin, and it has snapped (broken), it is likely, due to the interference fit of these pins, that the pin (now in three pieces) is still in the handle and the threaded spindle of the jockey wheel. If this is the case, it may be hard to see the roll pin as they are a tight fit and with some dirt and paint are even harder to see. If you do find a roll pin has been used you just need a hardened steel pin punch of the correct diameter to punch the broken pieces out. To fit a new pin you just align the holes in the handle and spindle and lightly tap the new roll pin in place. As someone else said, his Kimberley camper uses a grub screw so in all likelihood yours will be the same and you may just need a new grub screw (not to be confused with something you have at meal time) If it is just a replacement of the grub screw that is required, make sure you align the end of the grub screw with the recessed section in the spindle prior to tightening the screw. Whatever method is used to secure the handle it is a good idea to keep the threaded section of the spindle lubricated so it operates freely thus reducing the load on the handle (and the effort required to turn it)
As others have said, jockey wheels are cheap but I would rather spend $1 than $50 to fix the problem.

Thanks everyone for your help. The grub screw was very very loose. All better

Thank you Whirlwinder for that info. I went out today and bought a tube of Threadlocker Low strength. Will fix up that little grub screw tomorrow. Thanks for your hint. Linda
