Steel Knob - Manutec

Steel Knob Jockey Wheel Handle with Roll Pin from Manutec

The steel knob roll pin model fits worm drives with a smaller hole. Push out the old roll pin with a punch or a nail with the point ground to a flat.

AL-KO models have a larger diameter roll pin than the comparable le Manutec model.

Nut and bolt Handle is used on jockey wheels with holes in the worn drive.

The grub screw handle is another option but the worm drive has no hole through it. Instead, the top drive has been counter-sunk to accept the head of a grub screw.

AL-KO and Manutec grub screw models are interchangeable.
