So What Happens Now
Just started to strip my 1.6 pinto down and found this mess.
Question is whats the best way of tackling it. Can you still get ring gear ?
Is it possible to do it at home ?
Done it when I was a kid with my Dad but can't remember how we heated it up !
Any suggestions ?
Cheers
RD

Unless you have a oxy torch and the experience to get it off chuck it and buy a new one..
Burtons will help you..........

Give it a belt with a soft hammer and see if it will go back on.
If not give it a whack to get it off and see if its actually bent. If it is, find another flywheel, should be reasonably eas to get hold of. If it
isnt, heat the ring gear up in the oven @100deg then drop it on the flywheel (will still need some persuasion).

burton do ring gear, paid a local engine place 20 quid to fit (after i'd failed, he said he really struggled).

Burtons do new ones
It is possible to do it at home but you need to freeze the flywheel and heat the ring gear up with a gas torch.
We did it with a BBQ and left the flywheel outside over a cold weekend.
Big problem is if you get it wrong it is very hard work to put it right.
I would use a local engineering firm, probably won't cost more than £20.
To get the old ring gear off cut 2 slots either side as close to the flywheel but still safe then use a cold chisel.
If you take the flywheel to an engineers get them to turn off the weight at the back for a cheap lightened flywheel

A hole drilled into the side of the ring gear between two teeth and application of a cold chisel will split it and allow easy removal, but I have just
knocked one off by working my way around it with a punch and big hammer in the past.

Give it a belt as others have said. What have you got to lose you can't make it any worse can you really. If it works fine if not a new ring
gear or s/hand setup will still be an option.
If it looks wrong it probably is wrong.

I will try the "Big Bang Theory" and smack it with a lump hammer 
After cleaning it off of course.

cant you press it on using the vice?? this would allow incremental adjustments use an old socket etc placed onto the ring gear and tighten vice
Life is like a bowl of fruit, funny how all the weird looking ones are left alone

From past experience, removal is easy, but when re-fitting, heat to a dull red and drop on. do NOT be tempted to 'tap' it on as any impact
will effect the ring gear. The effect will be that it will eventually spin on the flywheel. Speaking from experience, it will do it at the most
inconvenient time.

I wonder if it would make any real difference to the starter motor operation at all?

soak it in WD40 before you start whacking it

2 things...
1. Did the engine start OK before hand? It may not even be an issue.
2. How much is another flywheel from the scrappy? It surely can't be worth the aggravation of messing about removing and replacing the ring
gear.
Just my 2p worth being one who likes the path of least resistance

Even if it didn't it would affect the balance of the flywheel.

Just try and get a second hand fly wheel if you can;t straighten it.
Or look at getting a Super Light weight Jobby as you now have an excuse....

will it? the mass is the same all the way round but it may wobble to and fro since it is not evenly distributed but I'd be surprised it that
would be noticeble, dunno for sure.
put the lot on BBQ, get nice and hot, then apply damp cloth to flywheel and tap down the ring.... ot just tap the ting down to striaghten it.
clean up the edge of the flywheel first as it looks a bit rusty.

Exactly...the same reason why you have weights inside and outside you wheels when they get balanced. Obviously it's nowhere near as wide as a
wheel and tyre, but it does rotate 3-4 times faster.

Under no circumstance heat until dull red !!
Ring gear will soften and wear out in no time IF it ever shrinks enough to fit the flywheel

The Oven / Freezer method never gave me enough clearance to 'drop' the ring gear onto the flywheel, but when an engineering firm in
Northcamp fitted it for me, that was their method. Fitted tight and lasted until I sold the car more than 30K miles later.

Taken from a Ford service bulletin , When fitting a new ring gear it must be heated evenly to a temperature NOT exceeding 600 degrees F (316degrees C)
otherwise the ring gears wear resistant properties will be destroyed. If the ring gearis to be heated on a naked flame place the ring gearon a bed of
fire bricks and then play a flame in a circular motion onto the bricks about a 1/4" to 1/2" from the inside of the gearuntil it reaches
the required temperature DO NOT PLAY THE FLAME DIRECTLY ONTO THE RING GEAR!. The correct temperature can be detected by using either a temperature
sensitive crayon or by polishing a section of the ring gear and heating until it becomes light blue .
Allow the ring gear to cool naturally DO NOT QUENCH.
Red hot is a damn sight hotter than 316 degrees C!!

OK, I give in - You win...
It was a long time ago on a trusty old Mk 1 Cortina - Ring gears got replaced a lot more often then than now with tho old interia starter gears.....
