I think that Jared is onto the problem. I'm not entirely certain, but there is a part, between the crank and the flexplate, (flywheel,) like a pilot bushing that the front of the torque converter slips into. Maybe someone here knows ~ Bill perhaps? ~ if that part is different for the Ranger and the Explorer. If so, that would be a likely cause.
It is ahead of the flexplate and my just look like part of the crank if you don't know it's there.
I just looked at the Motorcraft site...it lists the same engine for both Ranger/Explorer. Unless = the vehicle was sold new in CA.
Some flexplates require a re-inforcement plate (Ford basic p/n 6A366).
It's usually 4-6" in diameter depending upon the application.
I STILL believe the two dowels (6A008) went missing when the engine was re-installed. No dowels = engine alignment problem...center of flexplate tears out.

thanks guys!
my truck is gettin fixed as we speak!.. im gonna mention the damaged /bent bellhousing? and i told him about the dowel pins he's checking it out. as soon as i get it fixed im gonna upgrade to a 2oo5 ford escape, because im goin off to college & need something reliable..its still a ford [=... thanks again.. for all your helP! >!EriN!<
Good plan. If your college is anything like mine, you'll be happy to have something short wheelbase you can cram in all kinds of small parking spots and parallel spaces.
hey girl,
too much end play in the crank shaft in the engine.that is what cracks flex plates!
it will move foreward and backwards. depending on the miles on said ranger! and how much the motor is worn as well. they pull against each other. under acceleration the crank will move forward, and at the same time the torque converter is pulling the opposite direction. due to front pump suction. hense broken flex plates. and ruined starters.
His truck is not so old. This trouble is tipical for 600-800K engines. My old 3.0 with 700 k on clock has 0.7mm play. It is not normal but not enought to damage flightwheel.
that will work with me if you can figure out if the starters are the same.. ive heard different .. it is the same it isnt the same.. so i was just gonna see!.. thanks for your help! and the dowel pins are still there.

Well, from the beggining. I tried to read all the suggestions from the beggining and I cann not understand what destroys all. I wanna see pics. I may help us to understand what a hell is going on....
Go back to this plate that Bill mentioned:
Some flexplates require a re-inforcement plate (Ford basic p/n 6A366).
If that is absent, or on the wrong side of the flexplate, when the bolts are tightened then the flexplate is stressed right where you breaking has occurred.
isn't there a spacer between the crankshaft and flexplate?
ford ranger
Yes, it also acts as a pilot bushing for the front of the converter.
That part, spacer, whatchacallit is what I was asking about earlier, is it the same part for Ranger and for Explorer?
But the main point is, when the assembly is bolted together, is the flexplate stressed in any way?
Kevin:
Sounds like you described my problem. 1986 Ranger, 2.9L with Auto. Starter has been making terrible noise for a couple of weeks. Thought it was the starter drive, so replaced it, but no change. While starter was off, I checked all the ring gear teeth, and they looked OK (for a truck with 190K on it). But I figure the noise was the flex plate wobbling cause last night, stopped pulling, like a bad trans, but starter spins but does not rotate engine. 2-3 hours huh? I think your record is safe! Thanks for the info, looks like a fun weekend ahead for me.
