A replacement stub shaft for mounting a motor encoder pulley to the shaft of a motor on the X5 simulator.
Remove the prior motor shaft with a Slide Hammer Pulley.

- Lock out/tagout the equipment
- Tag and remove all wires and cables
- Remove the motor fan shroud using a Philips #2 screwdriver to remove the three screws
- Remove the existing stub-shaft from the motor with Slide Hammer
- Clean any epoxy debris, or burrs from the motor shaft using a fine grit sandpaper or a small file
- Prepare the new supplied Stub shaft for heating by setting it to where the large end (bell end) will be aligned perpendicularly to the flame.
- Make sure you have a pliers and a steady hand for gripping the stub shaft and rotating during the heating process and also for installing onto the motor shaft.
- Heat the bell end of the stub shaft by aligning the torch and rotating as it heats and turns colors.
- Once heated to a purple/grey hue, place the stub shaft over the motor shaft and tap it gently onto the motor shaft until it bottoms out onto the plastic fan. (DO NOT pound the shaft through the plastic fan, or into the fan forcefully; this needs to be done with a gentle touch!)
- Once cool to the touch inspect the stub shaft for bruises or scars and repair them with a small file.
- Reinstall the plastic fan cover.
- Install the timing gear on to the new stub shaft with the screw side against the plastic fan guard using two set screws and mid strength thread locker.
- Re-Install the encoder bracket assembly and belt
- Tighten all adjustment hardware.
- Reinstall cables
- Reenergize the machine.
- Run a test cycle while observing the new hardware.
- Check for belt tension; a loose belt will cause the attraction to shutter/vibrate abnormally.
- Check and ensure that stub shaft was installed correctly. If this was not done correctly the shaft will have runout and cause the gear to wobble excessively
- Check alignment. If the gears are misaligned the belt will want to walk from one side to the other when the motor changes direction. A slight bit of misalignment is acceptable, but the closer the alignment the longer the belts will last.
