Title: My 164tooth 5.0 flywheel T5 solution on the cheap.
Post by: CougarSE on January 02, 2007, 10:08:53 PM
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.

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.
