Topic: help for buying flywheel

[Trinita]

   
Hello everyone,

Any new on this forum:) my car is a 1967 fastback

Today I had assembled my new transmission and my new converter but my converter is not compatible with my old flywheel.
Transmission: http://www.summitracing.com/parts/TCI-511238/
Le converters: http://www.summitracing.com/parts/TCI-450738/
   
I'm going to buy a new one but I need some help finding the right one.

So the one I currently have 164 teeth but I have a new converter bolt pattern of 10,500 and with the bolt patern there is no flywheel with 164 teeth. only 157 teeth were available.

Is it important? Is what I must also change the pinion of the starter?

Otherwise here 3 compatible with bolt patern of my converter (10,500 and then 157 teeth). Only I must know Engine Balance.  3 différents :
External, 28 oz. imbalance : http://www.summitracing.com/parts/TCI-529618/?image=large
External, 50 oz. imbalance : http://www.summitracing.com/parts/TCI-529610/?image=large
Internal : http://www.summitracing.com/parts/TCI-529615/?image=large

   
Here is a picture of one I currently

The 64 tooth, 50 oz, flywheels didn't come out until like 1981. So shop for that date and up to find one.

Thank you for your reply.

why have you changed your initial answer?

Do I have to change the pinion of the starter of the engine? or will it be compatible?

So if your thinking I'm currently not good flywheel that is on my car??

Hi Trinita,
I replied to your question in the French forum but we need to know what engine is in your car. You either have to replace the flywheel + the bellhousing or buy the right torque converter. I think the second option would be cheaper.

The 64 tooth, 50 oz, flywheels didn't come out until like 1986. So shop for that date and up to find one.   

Yes but on the engine in the picture, it's an internal balanced flywheel.

[Soaring]

All I can see is a red X.  No picture of an engine.  That is a typical 57 tooth  28 oz flywheel in the link.

I changed my initial answer because I misread your post. I thought you were looking for a flywheel that was compatible with a '60-80's Ford engine.  Like Thierry said.  You really need to be more specific about what engine you have. 

[Thierry]

We figured it out. The car has a 289 and the 164 touth flywheel has a 11.5 inch bolt pattern so we found at what torque converter he needs.

Good.  The 289-C4 or 4-3 speed manual will not accept the 164 tooth flywheel.   The 157 is the only flywheel it will take.  The imbalance will be off and he will have a bad vibration even if he can get that big flywheel to fit, which he can't.    Now, if he has a different and more modern transmission, then maybe it will work with the right torque converter, which I see you have been able to find to fit this application.  Am I missing something here?  Maybe I should learn to speak French.   

[Thierry]

It seems that some 289 did come with the 164 flywheel:

Ford     289-351C-351M-400M    0 oz.    11.5" bolt pattern, 164 tooth

http://www.tciauto.com/Products/Flywheels/

I didn't count the teeth on the photo Trinita posted but if he says his original flywheel has 164 teeth, I believe him.

[Soaring]

A "0" ounce flywheel has been modified by drilling holes.  The original 289 had a 28 oz flywheel. 

"Due to the flat design as opposed to the dished construction of stock Ford flywheels, these flywheels will not work with stock replacement torque converters. "

So, if you were able to get a converter that will
work, good for you.  But a 164 tooth flywheel will not fit into the bellhousing of a C4 or a 3-4 speed tranny.  It appears he has put in an aftermarket tranny, and that the 64 tooth fits.  I guess there is more than one way to skin a cat. 

[Thierry]

I think I am going to have a headache. 

Here is a 64 tooth one with 0 oz, just like the one the OP posted and they say it works with 289 engines : Link

Flexplate features a 11.5-inch bolt Pattern & 164-tooth ring gear.

I recommended him to order one of the following converters with 11.5 inch bolt patterns :

I may be wrong but it seems like the right setup for him. What do you think?

[Thierry]

It seems you were right Soaring. The engine block in the car is not a 289 but a 1985 5.0L.

Seeing the picture again, it seems that the flywheel had weights at one time so do you have any idea why they would have removed them?

[Soaring]

1981 is about the year that Ford started using 164 tooth 50 oz. flywheels so  they didn't have to add so much counterweight to the rods/crank as the earlier 28 oz flywheel did,  so now I believe him too.  I guess the PO was trying to make a 0 oz. flywheel, but that would necessitate balancing the engine internally.  The only way to know that would be to tear into the engine, and see if it has been internally balanced.  It's possible that it has.    You say you saw that from the picture, but still there is only a red X and no picture of the engine, and you can't tell if it is internally balanced from the outside. 

[Thierry]

What I am saying is that it looks like the flywheel was balanced with weights welded to it like this one.
[attachthumb=1]

If the engine isn't internally balanced, would vibrations in the car be felt with a 0 oz flywheel?

[Soaring]

Absolutely.  If the engine was not internally balanced, and the previous owner shaved off the balance weights on the old flywheel, he will absolutely get a vibration from the engine.  If he is experiencing vibrations now, then he needs to get a 50 oz. 64 tooth flywheel. 

[Thierry]

No, he says he didn't notice any vibration so he should be fine with what he has. Thanks.

[Soaring]

Yeah, his converter must match his current flywheel.  I guess that was the original question in the first place.  It is difficult to diagnose problems on the internet without having the car in the shop and hear first hand what the problem must be.  If there are no vibrations, and the car runs great, then why the question that has wasted yours and my time?   

[Thierry]

Because with the help of my question and your reply I now know that he shouldn't worry about replacing his flywheel. I don't like to waste my time either and I wouldn't ask a question if I am not looking for an answer.
