What sort of extractor/puller fits for removing the front sprocket on my NC30. or hints in moving it

I think its the original sprocket and it wont bloody budge using the normal methods!

Any info

I did this yesterday! Original sprocket too and it was a bit rusty. I split one of my socket heads trying to take it off!
I used a breaker to take off the bolt. I sat on the bike whilst it was on the abba stand. Foot firmly on the back brake and push down hard on the breaker. The sprocket came straight off with lots of WD40 and a cloth wrapped around it. Lucky me.

Id imagine one of those with the 3 legs would do the trick. Have got a gas torch or something similar? bit of heat and a few light taps should free it

yeah, that was my next step, think i will wait till all the gunk and parafin has dried up before i put the blow torch on it!

i remember mine being a bastard toget off and in the process ended up with a big bump on the head as my foot slipped of the wratchet and the socket shot up and hit me, bit of a mr bean moment, got it off in the end by using a long metal bar over the wratchet as better leverage

Ive got the bolt off just cant get budge the sprocket and i havent got an extractor, will apply a bit of heat to it tomorrow and give it a smack!!

Got the front sprocket off from the project bike recently, very tight fit of the bolt so I applied some WD40 and half an hour later used some heat with a temperature adjustable heat gun (Steinel) at around 300 degr.celsius for max. 2 minutes, then with the correct socket and long torque wrench both the bolt and sprocket came off easily.
