Varitronic flywheel

[Speed Demon]

The stator is the same (albeit on a different back-plate), and while I haven't tried it I'd be extremely surprised if it didn't work.

mine went the same way,,, take out the boss and replace with a indian one that suits your crank from scooter restorations,, buy the kit,, boss nuts bolts washers the lot,, it fits perfectly in the hole left by the original peice of cheese but the holes dont all line up for the bolts but a bit of a fettle and all will be fine.

When you say all of the holes don't line up, do enough of them line up to get the boss central or did you have to do a lot of jiggling around to get it correct?

Also I presume you needed to locktite the nuts but did you weld them as well.

Basically what I'm asking is was yours on a tuned motor and how is it holding up with the way you fixed the nuts and bolts.

Sorry for all the daft questions.

Cheers.




Actually just thought of a not so daft question.

What do you do to hold the flywheel if you have taken away the varitronic boss with the large nut shape on it.

There are no holes to put a normal holder in once the sil boss is on there, or have you got away with holding the flywheel with a screwdriver to screw the puller in (being careful not to break the plastic fins) then using two spanners on the puller?

Cheers

angle grinder disc changing tools on some have a large centre hole so if you drill matching holes in the boss u could use that

Where would these holes be drilled, I would have thought the 8 bolts use up all the space on the boss, and I wouldn't want to make it weaker by drilling more holes.

Hello, I think this might be the safer option. Does it use the same nut as a standard flywheel and the same puller?

Also have you any idea ref the spacing between the holes for the flywheel holder, as I do have an angle grinder tool which might fit the spacing.

Cheers.

or in reverse
leave 2 bolts longer ,double nut them and drill 2 holes in the disc tool

Seems fair enough, this is the cheaper option, but I do like the idea of the one piece flywheel i.e. the Casa Casatronic Parmakit one or whatever it is called !!!

if the boss taper is not damaged and the magnets are not damaged,then your in luck just bolt it back on with some high shear strength allen cap dome heads and nylock nuts (ring cam lam for the correct place to bolt it up though,or a mates) get it back together for the price of 6 bolts!

when you take off the cheese boss the big hole it leaves is a perfect fit for the new boss,its spot on in the middle,, its just the smaller holes that dont all line up,, as i remember a few are dead in line, but the rest are a bit out and a dremel sorted them,,

Basically what I'm asking is was yours on a tuned motor and how is it holding up with the way you fixed the nuts and bolts.

its on the sprinter,, done a ton many times over a standing quarter,, nyloc nuts and thread lock

What do you do to hold the flywheel if you have taken away the varitronic boss with the large nut shape on it.

i got a large pair of stilsons that bite on the nuts around the boss,, works a treat

youve not answered my question about the taper and magnets,please inspect i may buy flywheel if there is no damage to the magnets!!!

Sorry didn't realise it was a question, it looks like a statement to me.

Anyway there is nothing wrong with the flywheel itself.

The taper is fine as are the magnets, the centre boss stripped when trying to remove it.

In fact it still works fine but I need to adjust the timing as it is a bit advanced.

So I have ordered a sil boss and am going to attempt to repair it.

Cheers.
