My Ongoing Clutch Problem

[Brentwood Bob]

Not necessary to get ring gear red hot to install. Flywheel cold (use dry ice). Ring gear under 1000 degrees F. (No color). I noticed that the broken ring gear is raised up off the seat.

Put the ring gear in the oven,throw in some potatoes, if your significant other complains just say you saw it on the ford barn,put the flywheel in the freezer.

Flywheel off, ring gear came off easily with a couple of soft taps, waiting for the new ring gear and then find someone to fit it, meanwhile here are some pics fresh off the press.................

It still looks like a normal weld to fasten the ends together. Is it a crack, or just looks like a crack?

Is the first picture after you tapped it off, then you just layed it on top for the picture?
They should take a lot of hard hits to remove them.

I just lay the gear on top, then go around with a torch to expand it until I can tap it into place. Work fast because it will cool quickly when it's in contact with the flywheel. I like to use a brass bar and heavy hammer to drive it home.

Did you mark the crank and flywheel, so they go back exactly in the same orientation?
If not, then look for witness marks to locate the flywheel. Usually you can see rust spots, or oil stains.

The first pic is how it was when the flywheel came off

Same here with a brass bunch and a strong flame

3rd and 4th pics show both sides, sure looks like it`s cracked, only a couple of taps with a soft faced mallet and it was off.

 

[Tom Wesenberg]

Hold the ring by a string, then tap it with a small hammer. If it has a nice ring to it, then it isn't cracked. However, since it slipped off so easily, it still needs to be replaced.

That first picture shows the ring gear only halfway on.When these guys are telling you there should be no gap between the ring gear and flywheel,they mean between that rear flange and flywheel,not in line with the crankshaft.If you were to reach in BEHIND the ring gear with a feeler guage you should not be able to slide it between the gear and flange.I had one like that for years,every couple of years I would have to reach in the starter hole and drive the gear back until it seated again.

 

[DennisR]

You`re right Tom, it`s not cracked, just did what you suggested, made a lovely ringing sound and as I removed the string you could still feel it vibrating after the ringing had stopped, also had a much closer look with a magnifying glass, not cracked................is it common for them to loosen.............SIZE]

I've heard some repro gears were made a bit loose. The last one I installed was so tight I had to use extreme heat from an ox/acc torch, then still beat it into place.

I agree with Tom some of the early ones were to loose. I had to pin the one on my Coupe a few years back.

I'll bet you can use a center punch on the flywheel in several places, then use some Loctite to hold that original ring gear in place.
