Helping a mate set his timing and the threads are knackered on the boss......any tips or alternatives for removing the flywheel ? Only option i think of is welding a nut on the boss and running a bolt through....

2 or 3 legged puller?

That got mentioned Joe but I wouldn't have thought you could get them in the windows with the stator being in the way.....unless there is a "Lambretta puller" out there ?

I'd try another puller first and make sure it's a good quality one

^+1 ^ ive had that as well

A friend of mine try the clutch tool in an unorthodox way: and it worked fine.....

there was comment on LCGB, I think, a few years ago, about a bloke with a similar problem.

He undid the flywheel nut and then started the engine and revs it up and down fairly brutally.

Anyway, to cut a long story short, the said flywheel did eventually part company with said taper........

However, in view of the "stored" energy in said flywheel, it took off across the floor of his garage; punched a hole in the wall; and ended up across the road in his neighbours garden, having first tore its way through the neighbours wooden fence........

Glad it wasn't leaving time at the local primary school!

Perhaps not the best way to seperate flywheel from taper

Back in 1971 my TV175 started misfiring so when I got home I took the side panel of and gave it a fistful. I didn't have and cowlings on or rear runners so when the flywheel shot of the crank and landed on my toe spinning at about 5,000 RPM I was a little surprised It then shot off down the drive, across the road and down the drive way of the house opposite finally smacking into the door of the garage a good 70 - 80 feet away. Felt a right tw@7 have to knock and ask if I could have my flywheel back Not the mention the great big hole that the fins 'milled' out of the top of my boot and bruising to my toe

BTW, welding the nut on gets my vote if a better puller doesn't work.

thats the story! when I first read it some years back I nearly shat meself with laughter!!

I saw Harry Barlow tack weld the puller into the flywheel boss and remove the flywheel in the normal manner. He then cut the tacks away and removed the puller. Because the puller was a long way into the boss there was still plenty of thread left on the puller so it could be used again. The boss was knackered so a replacement boss was going to be fitted. Scooter restorations sell replacement bosses.
