Technical flywheel teeth missing what now

[RobTi]

Hi daughter has a 1.2 16v auto '02 plate and it was having trouble starting so got a reconditioned starter and asked me to fit it.

Well discovered that around 6 teeth on the flywheel are broken.

So is it worth fixing 11 months mot left full service and 60000 miles,and all in all good condition

Thanks

Robert

you will need a new ring gear

or a complete 2nd hand flywheel - as your going to need to drop the box out and remove and refit the flywheel

Alot of work - if your able good for you - but if you aren't it could get expensive....

The only bit requiring a degree of skill is putting a ring gear back on. (you need a lot of heat to expand the gear to get it on/off the flywheel -- but anyone with an oxy/acetylene torch will be able to do it - in the olden days it was a common problem and some folk managed to do it with a gas ring ). The rest is just the simple, but labour intensive, job of removing the gearbox and flywheel.

At that kind of mileage, it's well worth doing.

You should be able to pick up a flywheel (my guess is that a manual car will use the same gear ring -- check with ePer) for very little off a scrappy.

thanks for the replies it's an auto would that make a difference, also does it have to be a specific ring gear\ flywheel for that model

My guess is not. Check with ePer for parts numbers -- if you can't find one for the ring gear, the same number for the starter motor will confirm. All manual FIRE boxes (except, maybe, the TJets) use the same ring gear, although the flywheels are different from model to model.

of course if teeth not totally shot you could either put the ring on again 190 degrees from where it is now or put it on backwards so the starter hits it from the other side

its what we did during the war

surely if I rotate the ring then it would work back round to the broken teeth over time

i dont think anyone replying to this thread has even seen a punto auto fly wheel, ring gear for these is just spot welded on.

your best bet is to just get a used one from a breaker or friendly forum member
removal and refitting the auto box its twice as easy on an auto to manual

engines always stop at a certain point on the compression when turned off this is why most wear is always at one part on the ring gear

no never seen one
doesnt sound an ideal way to keep things true either

the auto fly wheel is about as thick as a pizza box,

wait there..

don't forget a heavy torque converter bolts to that ( must be unbolted before removing gearbox)
