Assembly
Once assembled, clamp the ‘A’ and ‘B’ bolts tight. Set the 360° fit by inserting a ø8 mm bar (e.g. Y bar) into the bearing assembly. Tighten/slacken the two lower adjuster bolts (‘C’) until smooth running is achieved. Ensure all bearings rotate when the bar is slid up and down.
Y bearing 180
Two pairs needed, one with a ‘left’ outer and the other with a ‘right’ outer.

Assembly
5 washer stack either side of bearing. Once assembled, insert a ø 8 mm bar in between the bearings and clamp the slotted bolt to achieve a smooth run. Ensure all bearings rotate when the bar is slid up and down.

Assembly
Ensure all bolt heads sit on the underside of the chassis and bolt shanks point up. This guarantees that the chassis assembly will not collide with any of the frame structure it moves in. Bed will be attached later.
