Transmission Won't Slide On

[whitemike]

Lol i had a recent thread about that...

The bolt just keeps tightening, and tightening. Not like a stripped thread where it gets
tight then loose tight then loose... But it just keeps getting tighter, i've had it tq'd well over the TSRM spec
and i dont wanna go any further, last thing i wanna do is heli coil my damn crank.

Is your motor seized? I think something may be wrong if that much torque isn't turning your crank..

If thats the case the clutch install is the last thing you need to worry about my friend. CHeck out whats going on withthe crank AND bolt, take it out and inspect the threatds. It might be something as just replace the bolt and DONT TORUE IT "WELL OVER TSRM".

Well see this is the funny thing, i wasnt able to turn the crank by the front big bolt but as i aformentioned when
i had the motor hoisted up and i was installing my flywheel and tightening all my arp flywheel bolts the crank turned rather
easy?

I know, makes no sense to me either.

I had my motor filled up with oil and then i drained it all.

Could that be the culprit? No oil? i mean there should still be enough oil between
all the bearings to do just 1 full rotation....

 

[SupraRon]

My engine currently doesn't have oil and hasn't for 8 months almost and turns rather easily. There's gotta be more to it.

Hold on...

You just rebuilt the motor and are now NOT able to turn the motor over by hand?
You need to quit worrying about installing the trans, and take the pan back off.
You have got a MAJOR issue, dont even think about installing this motor.

Wasn't like a full rebuild, just new clevite 77 rod bearings, main bearings, thrust washers, and rings.(Bottem end anyways)

When and before i put that oilpan on i was able to grab my crank and turn it.
I just dont understand, if i have to pull that motor again and do something to those
bearings then im out of the supra game for good.

This is just rediculous and i have no clue what i have fucking did wrong.

I am almost positive there is nothing specific to a supra motor that would require you to do anything special to avoid the problem you're having.

you really can't turn it? There should be plenty of lubrication if you put oil or assembly lube on the bearings at install. That lube doesn't easily disappear on an installed crank.

With the head on, there is quite a bit of resistance because you're compressing the air in the cylinders as well as fighting the inherent friction in the bearings. Unless you installed something horribly wrong or left a tool in the oil pan or something I don't see how the crank could seize...

Are you sure about this?
After the bottom end was done you could spin it freely? Then you put on the pan on and now it wont turn? The pan would have to be horribly mangled to contact the crank.

if i have to pull that motor again and do something to those bearings then im out of the supra game for good.

At this point the bottom end is still savable. But yes, if the motor is in, it has to come out, and the pan has to come off.

Just to clarify. You are putting a big ratchet, on the crank pulley bolt, and it wont turn?
Is the flywheel contacting anything?
Does it turn with the accessory belts removed?
How about with the timing belt removed?

Dont let a simple mistake kill the project. Sit backs, gather yourself and fix it. When you find the problem, you'll be glad you didn't scrap it.

Yes i do not understand why the motor is seized either, maybe ill try to remove the sparkplugs...

Yes im using a big breaker bar,
No the flywheel isn't hitting anything and its not even connected to the clutch. (Inspection plates are off so i can see)
I dont have any belts on except for the first one that goes around the timing gears.

Its hard not too, && Just for clarification guys when i was doing all my bearing clearences i posted them on here and IJ helped
me out and said they were fine and even a bit larger gap side.

So i know it has nothing to do with my clearences. The only thing I DIDNT check clearence wise was those thrust washers,
After i put those on my crank got much harder to turn but i was still able to turn my crank rather easy with just my hands.

And as i aforementioned RIGHT before i installed that oil pan i turned my crank over 1 more time just to make sure it was good.

I appreciate everyone replying, giving me a little more hope...

 

[mkiiichip]

Take the flywheel off and see what happens.

 

[I6Boost]

Ok i've gotten a little further on the Siezed engine problem....

Pulled the motor, took the oil pan off and oil pump...

Crank still wont turn.

I take 1 main cap off, then try to turn it over,
nothing happens so i go 1 by 1 till i got all 7 off.

All main caps are off and crank is still locked up...

So i think my rod caps.

Take all them off, Crank is STILL locked lol...

I put all the caps back on and tighten them to tq spec.

Unloosen the balancer bolt and bam, crank turns like a free bird...

So i start inspecting my balancer but i see nothing wrong, its not touching anything but the crank, the inside
belt isnt pinched or anything, idk.

When i tighten that bolt to tq spec the crank is locked. i unloosen that bolt and crank turns super easy....

Took 4th cap off(middle one) and i take a look at the thrust washers, found my problem! i think,
i take a flat head dull screw screw drive and poke at the thrust washers to make sure they move, right one
moves super easy, left one is locked in place and wont move(Even with the balancer bolt unloosened)

So im almost %100 sure that my crank is getting pulled somehow.... I've talked to various guys and were all stumped.

If anyone can help i would appreciate it a ton!

 

[IJ.]

Bent crank?

 

[I6Boost]

Bent crank?

DONT say that lol! My heart just dropped...

Im almost positive my crank isn't bent...

It sits down in the saddels perfect, main caps go in perfect etc...

If it spins perfect without that front balancer tightened on then its not bent...

 

[IJ.]

Cam belt pulley the right way around?

 

[I6Boost]

I'm almost positive it is, will it go on the wrong way?

Ill take off the front timing cover and re-check everything...

But i dont see how the balancer has anything to do with that belt?

 

[IJ.]

Yes it can go on backwards, the Balancer bottoms on that pully which bottoms on the crank when tightened.

 

[I6Boost]

IJ YOUR THE sd;kfjNBSLFKlsfm!(Me excited)

Yep the stupid gear on the crank was backwards...

Turned it around, put everything back together, tq'd the crank
and bam she spun purrrfect..

hahaha im excited

Thanks a ton man! You saved me alot of time and sweat(102 Degrees in my garage atm lol)

Woo!

Again thanks man.

&& Yes you could see on the gear where the Oil driveshaft gear imprinted on it.

 

[IJ.]

Very welcome

i love IJ i always will...if i ever took a trip to aussie world..he would get a gigantic man hug from me.
