My '69 scrambler 350 has been sitting in the back behind british projects for over ten years and it is now on the table. I am pledging to make an effort to stay with it. (yeh, right). anyway I can't get the rotor to budge. Any tricks?

Tension on the puller and shock tap the flywheel “on” has worked for me.

Time, heat, patience, coupla sharp taps .. and repeat.

It's a taper. It will yield. Just needs to be persuaded ... nicely .

thats what I've been doiing except for the heat. wasn't sure whats under the rotor, or if the rotor could lose it's magnatism from the heat.

Think how hot that rotor and the stator behind it is getting when the engine is up to full working temperature, A bit of judicious heat won't do any harm, try tapping the outer edge of the rotor towards the centre of the engine with a copper hammer....this provides a tiny leverage effect against the taper and will aid in breaking it free (with heat and a well tightened up puller and a few sharp taps on the end of the puller centre bolt) "careful now".

And leave the puller bolted up overnight ... Often times, when you come back in the morning, the whole caboodle has come off overnight by its own accord.

Tap, tighten. Tap, tighten ... Cup of tea, bottle of beer ... Tap, tighten.

finally got it. It took all of the above plus a bit of side impact to loosen the grip on the taper.
