My 164tooth 5.0 flywheel T5 solution on the cheap.

I've told alot of people about this, and few believe it will work.  Just posting these pictures up to show the small differences between a flywheel that actualy belongs in the bellhousing i'm using and the flywheel i'm using instead.

Issue: I have a bellhousing for a sn95 length T5 that uses a 164tooth flywheel instead of the traditional 157tooth.

Solution: 5.0 truckflywheel is correct diameter and thickness and balance for my situation.

Bonus: 11" clutch instead of 10.5"

Con: Have to use 5.0 5 speed truck flywheel, oh well they come in mini starter too.

Don't: Tell me to buy another flywheel, my total investment is 20 bucks.  If I knew this wouldn't work I wouldn't have purchased said flywheel.

Here are the two flywheels:
These are both 164 tooth flywheels, the one on the left is a 5.0 truck flywheel and the one on the right is a supercoupe flywheel.



The only difference between the two.  Starter rings.  Why this is like this I don't know.  Truck starter fixes the issue.



Here is an 11" disc that fits perfect.



And here we have the pressure plate setting on the disk.  This is a supercoupe pressure plate and it fits the truck flywheel perfect.



Backside to show balance difference.

That's some top notch ingenuity.  At least get a new clutch?

Yeah those are just parts I have around..  I will probably mock it up with those parts to see if the engine infact runs right.  The clutch is a newer valeo.. its just rusty.

all sounds perfect and believe me,, ill need a final update so i can add it to the diy link,,,,,,,,,but..............

can i make a even more cheap suggestion?

oh,, nevermind. I see what you mean now.  the truck flywheel is sort of a reverse negative of the other one with respect to the ring gear.  I was gonna suggest you swap on the ring gear that complements your intended starter but the starter nose will be wayyyyyy toooo short.
gotcha.

so in a nutshell,, this would be a 5.0 10.5 to 11.0 cluch upgrade with boneyard parts and the specific truck starter/flywheel/clutch system.  correct?

i think you might be the one i should mention a situation to and get your thoughts or experiences about it if you dont mind.

Vehicle,,, 1990 full size bronco w 351 and E4OD tranny

swapped in a 1991 f150 5sp called a "MAZDA TK"
used all parts from the f150 and a ranger
new hyd slave/master, clutch,pres plate, throwout bearing and needle bearing, std drive starter ect.


this work was done in North Carolina. 

Anyways,, in a short time i rung out the starter bendix. I installed a new starter and less then a month later the starter and flywheel ring gear were shot.
Advance let me swap out both parts for new ones.  i used two long bolts in the top two holes in the bellhousing, removed the rest of the bolts, removed tranny mount and added a big block of wood there, dropped the driveshaft at the rear.
tied a wratchet strap to the tail shaft and the other end to the axle and slid the tranny backwards on the two long bolts in the bell.

i installed the new stuff,,,, and holly  all this stuff repeated itself.

Now its time to investigate. 

i found that the dumb asses had to make the standard drive starter head fit in the flex plate hole cause i could see where they ground down some metal in the flex plate hole.  Im pissed now.

I figured out after looking at approx 80 ford 302 flex plates,, only 3 of them allowed a standard drive starter head to fit.

I lay up my original flex plate to the standard drive flex plate and sure enough,, the starter hole is slighly offset by no more than 1/16'' perhaps a little more but still, not much difference.

i got to thinking,, yeah,, my starter is ringing out and the flywheel is ringing out,, maybe my bendix is too far away from the flywheel.

I install 1 of the new flex plates i found and problem solved.

ever had flex plate issues where the orientation of the starter hole is just a weeee bit off?
this may be common sense to some people but i guess its not.  I really wish those guys down in Morganton NC would have caught that during the job.
hell, they did not even know there was a difference in starters by comparrison of a auto to a standard drive.  I knew that much.
