Torque convertor to flywheel bolts
 

I have recently swapped engines and just got the trans and the drive line back in. i am now trying to put the nuts on the torque converter bolts. got 3 of them in no problem, turning the crank with a socket and a breaker bar. the 4th is proving to be a problem. clockwise and counter clockwise i cant get the crank to turn far enough to reach the last bolt. pulled the spark plugs to release the pressure and still no help.

any ideas?

losen the three bolts it might be binding up it could be twisted

Did you feel the two click when sliding on the converter? It may not be in all the way and is binding up.

The engine should spin freely with no plugs in it, unless it has internal damage.

new developement... uninstalled trans and torque convertor, still same problem...tweaked camshaft? any new ideas?

thanks!

Spins a bit and stops or not at all?

7/8 of a full revolution. About 1 1/2 inches short of a full rev

Help me out here !

The engine will only turn over ⅞ th of a rev, it doesn’t rotate freely with the plugs out ?

I must be missing something, are we talking about the engine or trans ?

I have to think we are talking about a SOHC motor not an OHV. Sohc motors are interference fit motors and you are probably turning the motor against a valve indicating the timing has jumped and a valve may be bent. A SOHC motor relies on oil pressure to keep the upper timing chains tight with hydrolic pressure. Anytime you turn one of these motors without it running it can cause the chains to jump.
If it's an OHV motor you have something hitting somewhere such as a bent oil pan or ?

x2 on something is wrong… That is what I have been saying, WTF is up.
It is a ’94 so I am thinking 4.0 Std Engine but no info in the profile.

Chk it out before going any further !

sorry guys, first time using the forums, and this is the first time i've have complications i couldn't figure out myself.
the motor is an ohv.

my trouble shooting consists of uninstalling the trans. and pulling the spark plugs. then marking the flywheel and the engine with a sharpie and turning the crank as far as i can both clockwise and counterclockwise. the end result is the same, it is about 1 1/2 inches short of a full rotation, the flywheel, in either direction.

X3 X4… chk it out something is wrong !
The engine should rotate completely around any number of times… unless there is something in the way.
Could be a valve, could be a bolt went in through an open spark plug hole, other things too…
Pull the valve covers and see if there is anything broken under there or maybe some parts floating around like Vale Locks or a retainer, maybe a spring or two.

Luck to ya !

I would look in the cylinders to make sure there isn't anything floating around in there. Like a piece of a spark plug or something.

You may need special tool called a boroscope.

This is the cheapest I have found one of these, if you have a store near by you could "rent it" if your morals are up to it.
