Coil Slipping

[Phill]

Hi Guys


I'm running a Zenoah G290 and after every run the coil is rubbing on the flywheel


I adjust it and after the next run it's rubbing again


The bolts are tight and I don't want to use Loctite in case it slips and I can't get the bolts out


Any ideas?


Thanks


Phill

Thanks but I don't want to use Loctite in case it slips and I can't get the bolts out.

I've had probs getting Loctited bolts out before even with heat

Well. Your coil will continue to fall otherwise. ..

You may try ruffing up around the bolt holes on the coil to give the head of the bolt some seat grip

Found the problem

One bolt is broken leaving only about 3/8 inch of thread going into head

It's broken too far in to get hold of

Any suggestions?

easy out will work

 

[Phill]

That should have been 3/16

a flat washer might help

 

[Phill]

Thanks mate

I ended up using the broken bolt and gluing the coil to the head with red loctite

So far so good

drill it / ease out! , get a slightly shorter bolt , or trim one. it likely bottomed out and broke. if its bottomed out , something maybe missing...lock washer, flat washer[coil] plastic spacer. the spacers can be split look for that as well.

the red may hold for sometime

I used to watch F1 but it got boring

Being a rider (ZX 11) it's usually MotoGP , occaisionally Nascars and if I'm up early enough Monster Jam

Trouble is bolt was loctited in with red

I have a spare cylinder I'll use when needed then look at maybe drilling out and retapping.

While its going I'll leave it alone

i would do the same , run it . then tool it when its off.

fresh drill and it'll be over in a flash!
