20 minutes / wheel
no. 2.5 hex-head key (metric)
no. 3 hex-head key (metric; provided)
Loctite glue (anaerobic, low-strength)
1x DC motor
1x wheel tube
4x 2.5x9.5 self tapping screw (bigger one)
Put the motor inside the tube.
Rotate the motor so its holes match the ones of the tube.
Screw one of the screws. Don't tighten it.
Screw the rest of self-tapping screws. Tighten them together with the first one.
Step 1 assembly
2x ball bearings
1x waseline grease
Grease the tube surfaces that will match the bearings,
Put the rear bearing on the tube. It may be tight - just slide it gently and even on the pre-greased tube.
Put the front bearing on the tube.
Step 2 assembly
Lower wheel mounting
Upper wheel mounting
4x m4x12 screw
no. 3 hex-head key
Put the lower and upper wheel mounting together.
Put 4x m4x12 screws in the holes provided. Don't tighten them, just turn to keep them in place.
Put the assembly on the wheel tube. Make sure the brass inserts are located outwards. Rotate the wheel holder the way the brass inserts are aligned with motor cables (as in the photo)
Push the assembly all the way to touch the bearing.
Tighten the mounting screws.
1x Step 3 assembly
1x Wheel rim
1x m3x12 screw
1x m3 square nut
1x fi3 washer
no. 2,5 hex-head key
Push the tube assembly in the wheel rim.
Push all the way to meet the front bearing. There should be no gap between the bearing and the rim front lip.
Step 3 assembly
1x rubber simmering (sealing ring)
Grease the inner front part of the wheel tube.
Put the simmering in the tube.
Push the simmering with your fingers until it stays even in its position.
1x wheel hub
1x m5 torque screw
no. 2.5 hex-head key
anaerobic glue for threads
Put a drop of anaerobic glue on the screw.
Put the screw in a corresponding hole in the wheel hub. Don't tighten.
Open your lithium grease.
Put grease everywhere between the wheel tube and simmering. It will act both as greasing agent and as a sealant.
Put the wheel hub on the motor shaft.
Leave ca. 1 mm gap between the wheel tube and wheel hub.
Tighten the torque screw.
Step 5 assembly
1x torque plate
5x m4x8 round head screw
no. 2,5 hex-head key
Put a torque plate on the wheel hub. It may be tight, don't worry about pushing it all the way as the screws will do the job for you.
Tighten 3x m4x8 round head screws on the torque plate. Tighten them as shown in the photo.
Tighten the rest of round head screws.
1x wheel cap
1x rubber o-ring
3x rubber square inserts
Grease the square inserts.
Put the inserts in corresponding slots in the wheel cap.
Put the o-ring in a corresponding groove in the wheel cap.
Grease the o-ring.
Step 7 assembly
Step 8 assembly
Grease the motor cables all the way.
Put each cable in a corresponding rubber bushing hole. Maintain the encoder cable order.
Slide the wheel cap on the cables.
Push the wheel cap into the wheel tube.
