Anybody got a puller for one of these?

[Ixion]

Looks pretty straight forward. Three legged puller through the rivet holes, or a two (or three ) leg gear puller. I've got pullers that should get it off.

[SHELRACING]

I just used a 2 legged puller on mine, wrrapped a couple of zip ties around the legs and it stops them slipping. easy as :whistle:

[Pumba]

God Garath has done a number on that.

Just a warning from a previois owner. When it was converted from points to CDI I sheared a brand new keyway on that flywheel, and ended my days racing. When it was put back on I suspect (cause I wasnt there at the time) some very high strengh lock tight was used to "fix" the problem and this is why Garath butchered it so bad trying to get it off.

Bugger might need to warm the flange with some gas as well then.

Proper puller, big hammer and heat gun.

That's what I did, and it just bent it. It's well and truly stuck on there.

Try the heat option Squiggles.

[Squiggles]

Yep, fully going at it with the heat then puller by the looks of it :D

So did you get it off??

Getting around to it :Punk:

I got a gas axe.

We shall be in touch :D

Yep, I've got two. But I'm in Welliwood.

Cost me about $30 for one from a local bike shop. Fucken marvellous they are. Much better the the legged pullers.

[Ixion]

What size is the internal thread. I got an RZ puller, which from memory is 27 x 1 left hand. Might be 1.5 . That internal thread looks a lot bigger than that.

Well said Skunk, Spend the cash and buy the right puller , they fit older suzukis and yamahas, the RD and RZ engines have a longer stud out from the crank(looks like RX is the same) and the shorter puller of the 2 wont fit (not deep enuf) i have got the short type, that does most of my bikes and made a long shaft one when i had a machine shop to play with, to bloody ages(crap lathe skills lol) if i knew they were $30 i would have just bought one,
A 3 legged puller just wreck things :2guns:

what broke your flywheel?

[CookMySock]

If its already fucked, then cut it off with a cutting disc.

A 3 legged puller is what bent it.

I'm not sure why it broke in the first place, but it managed to shear the 6 rivets holding the flywheel on to that plate.

The rivots may have been damaged from pulling on the outside of the flywheel at some stage , i had a DT do that and managed to get the hub off(with the correct puller) and tap threads it, fit cap screws with loctite and nylock nuts and put the flywheel back on the flywheel hub, Bit off mucking about but didnt have a spare. I was just lucky the magnets wernt broken. Thats the nasty cracking noise you here when they bend with a 3 leg puller lol

You're taking the piss right?

[CookMySock]

You're taking the piss right?No.

Any more yanking on that with the puller and you will fuck the whole shaft. Dont do it.

Get a little angle grinder and put a thin cutting disc in it. Put some earplugs in, safety glasses on, and get some gloves on, and get comfy in a chair, and sit there and little by little grind away at it under it drops off.

You will be surprised how easy it is, and you wont bend anything.

Serious. It sounds horrific but its actually quite delicate. JUST TAKE YOUR TIME.

Steve

[CookMySock]

Make three cuts. First the green and the red cuts, then make the blue cut, then go back and deepen the green and red cuts.

Use a thin cutting disc, not a grinding disc. Don't worry about heat build-up that will help you, not hinder you.

Hold the grinder firmly with both hands or the fucker will bite and leap at you. Wear some thick jacket or similar.

Don't cut deep into the shaft. If you nick the shaft don't panic - it wont hurt it greatly. Remove the stator coil, and anything else in the way.

Steve

[Skunk]

Just get the right tool for the job. :sigh:

[Ixion]

Either the threaded puller, or a three leg through the bolt holes (not behind the rim like pulling a gear) will get it off for sure.

You have to screw the puller up REAL tight, then dob it a crafty sharp wallop with the BLOODY BIG HAMMER. You must use a BIG hammer, one sharp hard blow dead central, not bash the bejasus out of it with a tack hammer.

Retighten if necessary, and belt it again. Rinse lather repeat.

[RDjase]

No.

Yeah right , buy the correct puller and you can use it again and again , a grinder only works once and you have much more chance of cutting into your crank and FUCKING IT

[Squiggles]

Make three cuts.

Theres no fooken way im cutting it.

I shall measure when next in the shed and report to mr ixion, or buy said puller and see him anyway for heat :Punk:

[Ixion]

Heats a good point. It may have been Loctited on.

[CookMySock]

If you pull on that really hard you will wreck the threaded part, if you haven't already.

Heat is fine, but you will likely zap something nearby if you are using oxy/acet. Make a mask out of a bit of tin, and slip it over the shaft.

The safest way by far is to carefully machine it off. It will be done in ten minutes. It doesnt matter if you nick the shaft, as long as you don't whack a deep gouge in it.
