Torque converter/flywheel question (engine install)

[Anonymous]

Getting ready to pull and install my 1st engine and have a question. I am looking at my new torque converter and flywheel. There are 4 threaded studs on the TC about a half inch long. How does this thing attach to my flywheel? Are there nuts and washers? Or are there some type of pins or something that attaches to them?

Thanks...

super glue...


Ok, really......there are four studs on the converter that go thru four holes in the flexplate. If there is a drain plug on the converter, make sure it also fits into a slot or hole for access. Then you tighten the four nuts to secure the converter. 20-24 ft/lbs will do it.

Ok so I can bolt on the flywheel, TC and bell when the engine is on the hoist? Then the TC just slips on the shaft coming out of the trans? I thought there was more to it and the TC was tricky to attach to the shaft on the trans.

Install the converter before hooking up the trans to the engine. The converter will slide far enough into the transmission to allow you to line it up after the engine is attached. Rotate it as you slide it into the pump and you will feel the input shaft and the pump engage. The converter will clunk into place. Just slide it forward into the flexplate after the trans is connected to the engine.

It will probably be easier to stab the TC in the trans first then put the trans on the back of the engine.

You should be careful to get the TC all the way in or it will crush the pump. When you put the trans (with the TC installed) on the back of the engine, the trans should completely meet up to the back of the engine without forcing it.

When you look at the input shaft on the trans you will see two sets of splines and there will be two flats on the TC snout that drive the pump. Make sure everything is seated and you will be OK.

For someone who's new to these things, I reckon preassembling the motor and box can help. Then you just hoy the car's front up and lower it over the driveline. Works well on an early Falcon.

Ok Addo that makes sense. So I just put the front wheels up on my ramps and then bolt on the flywheel, tc and bell and install everything on an angle like that. I know I will have to rotate the engine while I slip it onto the trans. How much willI be rotating (a quarter turn, eighth of a turn)? Clockwise or CC? Is there any way to mess this up? I mean as long as the TC attaches to the pump I should be ok, right?

HI
The bell housing and the tranny should be installed as one peace.
attach the flex plate (fly wheel) to the motor.
put the TC on the tranny rotateing and pushing it to make sure it is all the way onto the tranny shaft.
then install the tranny/bell housing onto the motor. As you tighten the bell housing bolts make sure the TC lines up with the right holes in the Flex plate as not to bind it up and the bell should pull right up to the block with out probs.
In respect the TC should be able to slide front and back with the bell up agianst the block not much but it should be free and not binding against the flex plate..

But if I do it that way how to I bolt the tc to the flywheel?

 

[mustang6]

The studs sticking out of the TC will need to be lined up so they slide through their corresponding holes in the flywheel as the transmission is mated to back of the engine. Then from the opening (covered by an inspection plate after you are finished) at the bottom rear of the engine you will install one of the nuts on the studs, rotate the engine until a new stud comes into view, install a nut, rotate the engine, etc, etc. I rotate the engine one revolution to get all the nuts on just snug, then do another couple rotations to torque all the nuts to spec in a criss-cross pattern. Install the inspection plate to get dirt out of the bellhousing area and you are done with this part of the installation.

HI

Like mustange6 stated.
There should be a removeable plate eather on the bottom of the bell or in front of the bell to alow access the TC bolts.

I have also found that cutting away a small portion of the bottom of the bellhousing (big enough to get some fingers in through) helps a LOT when you are trying to get the torque converter studs into the holes on the flexplate (I have a big bell 200 and the gear teeth on the flexplate make it near impossible to get access to the TC to move it)
