I'd forgotten the bialbero motor has holes in the rotor - it's a long time since I've seen one. I can't remember how I held the rotor on the GFR when I had to have the stator rewound, but I managed it.

I fabricated a holding tool for my Morini from a piece of dural bar about 3 inches wide and half an inch thick with a piece cut out at one side to clear the rotor nut. Two holes drilled and tapped at the correct centres to take a couple of sawn off bolts for the pegs. I used it just last year (when I found it again!).

Blocking the rear wheel with a length of timber between a spoke and the swing arm was standard practice for me - don't try it on an RC600 ;)

Hi Twisty,
Like 72degrees I made a tool with 3 pegs fitting the rotor for my Morini, my Gilera puller has spanner flats and I just fit it finger tight and then use a socket on the extractor bolt and a spanner on the body of the puller, as Joachim suggested a hot air gun used for paint stripping could help, pneumatic impact wrenches are not usually found in the home :dry: When the extractor bolt is tight give it a good whack and tighten a little more before giving another whack
Good luck
John

I think he has not a problem with the puller. This one could be hold with a spanner.
He is locked one station before.
The bolt which holds the flywheel in place will not went out.
At least this was what i was understanding.
In that case a t-style tool will be a big help.
Sorry i have forgotten to have a look in my tool box. Send me a reminder if you need the measurements ;)

ciao Joachim

Hi guys - success!

Thanks for all of the good advice. I thought of using the heat/freeze option, but realised that my understanding wife might not be quite so understanding if things went awry...

In the end, a wooden table-leg through the spokes locked the engine nicely, and after that the bolt came undone. The rotor came off quite nicely - with a lot of leverage, a little swearing, and a judicious tap with a hammer. :)

Now - time to remove the belt, and there's a little phrase that has me scratching my head: "loosen the idle-roller nut and position the idle-roller in such a way as to enable the belt to come off the pulleys".

I've loosened it, but the roller doesn't seem to move much - a couple of millimetres perhaps. Certainly not enough to slacken the belt sufficiently to get it off easily.

Do I need to undo the nut completely, and remove the roller? There's a spring that keeps the idle-roller under tension - should that be removed as well?

Sorry about the never-ending questions...

A.

You should move the idle roller to the side while loosening the nut.
Pull it as wide as you can d oto the right side. Then fasten the nut by hand so the roller keeps in its place.
This should be ok to remove the belt.
If not, you can also remove the roller.
Be carefull that you do not mix up the washers on the front and rearside of the roller.
Refer to the workshop manual or parts list to do this right.
I have seen Nordie engines with both washers on the rear and both on the front side of the roller. That's not good for the belt i think.

ciao Joachim

PS also check the water pump roller. Should turn easy but not with slack. Cross my fingers, waterpumps are hard to get and cause serious damage when they felt
