R&G Heated grip puller

I used this to pull R&G 1" heated grips off.

Puller requires 8mm threaded rod and an M8 nut. Screw the nut onto the thread rod, heat it up (e.g. on gas hob!) and then push into the hex hole.

Use 2 more M8 nuts on the opposite end of the threaded rod tightened together to allow the rod to be rotated with a spanner.

* Unscrew the chrome end cap from the heated grip.
* Place a 1p into the pusher.
* Insert the pusher into the heated grip.
* Screw the puller onto the heated grip.
* Use a spanner to tighten the threaded rod.
* Go slowly. Wait some time between tightening quarter turns until it starts to move.
* May help to switch the heated grips on (but not too much otherwise the PLA can soften.
