Caster Wheels
Step 1: Build Caster Brackets
Parts Needed:
REV-41-1303 – Bracket, Motion (2 per side, 4 total)
REV-41-1361 – Nut, Locking, M3 (2 per bracket, 4 per side, 8 total)
REV-41-1359 – Screw, Hex Cap, M3, 8mm (2 per bracket, 4 per side, 8 total)
Hint
Screw the nuts onto the screws just until it’s difficult to turn them; just so that the nuts don’t fall off.
The screw heads will need to slide along the center of an extrusion in a later step.
Step 2: Add Caster Brackets to Chassis
Parts Needed:
Caster Bracket Assemblies
(4 – from the previous step)
Hint
Brackets must be installed 2 cm from the end of the extrusion, if used for competition, to fit within the sizing cube.
Ensure that the pair of brackets on the same extrusion are the same distance from the end of the extrusion or the wheels will not rotate properly.
Step 3: Add the Omni Wheels
Parts Needed:
REV-41-1327 – Shaft Collar (2 per side – 4 total)
REV-41-1326 – Bearing, Through Bore, Short (2 per side – 4 total)
REV-41-1323 – Spacer, 15mm (1 per side – 2 total)
REV-41-1324 – Spacer, 3mm (1 per side – 2 total)
REV-41-1347 – Shaft, 5mm Hex, 75mm (1 per side – 2 total)
REV-41-1190 – Wheel, Omni 90mm (1 per side – 2 total)

Hint
Order from the outside in: collar, omni wheel, 3mm spacer, bearing, bracket, 15mm spacer, bracket, bearing, collar.
Adjust axle length, so it is flush with the collar.
