G'day there
I have just started off on a restoration of a 1961 VBB Vespa, and have dropped the engine out and removed top end (cylinder up) and all is going well.
I am now rather red facedly (yes made up word) asking for advice about removing my flywheel. Yes I know what you are thinking (get a flywheel puller), and I have ordered now 2 pullers (both don't fit). The engine is a 3 port (so not original VBB 2 port 150 engine)... That was my fist unexpected surprise oh well will keep it VBB themed even if the engine is a 3 porter. Both (supposedly were Vespa pullers but my flywheel doesn't have any threads.. only the inner bolt thread where the flywheel nut was screwed on to. So the 2 Vespa pullers I got off ebay from scooter shops comes with out side threads on the puller.
So here is my newbie (oh look my face is bright red now) ask, any one have an idea as to what Vespa puller I need ? the nut came off easily and was a 14mm socket that got it off... the was a small washer under the nut but looking inside there are no threads on the fly wheel only on the bolt that holds the thread on.
Waiting patiently for one to respond....
and thanks in advance.

there should be a circlip inside flywheel an the nut should be shouldered ,as ya wind nut off it catches on circlip n draws fly off the taper , well thats the idea ,often circlip pings out , if theres a groove clean it out an either get a circlip n fit it or if its a thrust/circlip make sure chamfered edge faces in an 90degree edge out , it helps to put some tension on circlip with nut an then a sharp rap with hammer on end shocks fly off , ive had 1 that just wouldnt come, ended up suspending it a inch off my bench by rope passed behind fly ,touch of heat n sharp tap n engine dropped to bench , a riskier solution is to put a crowbar behind it down the part where airs forced by fan, not over the rim , an tap end of bar ,turning fly between taps ,eventually after loads of taps it will shift , heat helps here aswell ,but to much heat will fry ya stater windings , H ya avatar piccy, is that 1 of "learner legals" of pompeys scoots , i got my super from him , H

Thanks Henri
Will try the rope trick.... as there is no circlip or circlip grove that I can see

No I sourced the Vespa here in Brimingham (UK) it is an Italian import ... Obviously in need of a bit of attention... haha

have a good prod/scrape ,the grooves get filled with crap an even painted over ,if theres no thread there should be a circlip groove , if all else fails a 2/3/4 leg puller might do the job ,but at risk of damaging the flywheel edges , but if theres no groove/thread would you really want to re-fit that fly .

G'day Henri.... yes I agree the flywheel has previous owner(s) edge damage..... got chatting to a local Scooter repair / reseller shop and he suggested a 3 leg puller (which he had at home) so kindly offered if I could drop the engine into him he would pull it off for me.... Yep a new flywheel was always in the restoration project plan... I will reuse what I can but if in doubt will source some new bits....
Not sure I can shout out here (or if it is appropriate) but I would recommend Fargo scooter shop in Coventry.... helpful lads... (sorry in advance if this violates forum T's & C's - but I didn't put in their website so readers will have to do additional searching if they so desired).

P.S. With the engine issue I have at least I had a nice sunny day on Sunday to start stripping the rest of the bike, fun getting all the cables out of the headset, but front end all off now and apart and scoot getting lighter to lad (aka man)handle now...

That flywheel will have the groove in it, never seen one which has no thread and no groove, worth trying the circlip removal method for the sake of a 50p circlip, the puller will muller the flywheel and that's a cost you should be able to avoid..
unless you are going electronic anyway of course and need a new flywheel for that

as bryno says ,he's "never seen a fly without either a thread or groove ", neither have i ,an ive seen/owned/worked on loads of indian imports aswell as italians ,so its not some weird indian difference , but if flys already got edge damage n this guy reckons he's a puller for the job n wont charge the earth ,might be quicker than waiting on postie bringin the right shouldered nut n circlip to do it the proper way .

well hear you "dog(s)!!!!" but it doesn't have a thread... trust me I am an Aussie..... (haha).
Yep I have gone down the road of buying 2 "Vespa" pullers (good for getting off my new flywheel which will be threaded - trust me !!) ... And Bryno I am going to pull the whole motor in bits and the flywheel is cracked and chipped so wont be putting it back anyway...
Cheers for your advice lads... and I am sure I will be counting on you both in the near future with more annoying questions for you to laugh at- erm - mean answer !!....
