Removing Flywheel??

I have a 1994 F-250 and I am taking out the transmission. I have everything done except I am having problems getting the nuts off of the flywheel. I removed the starter and am trying, but can get the nuts to budge and its hard to get anything but a wrench in the work area. A socket does not have enough room to fit.

Does anyone have any tips or are there any special little tricks or tools I can use.

Thanks, Richard

The flywheel doesn't use nuts. It uses bolts, but you are saying you already have the starter off so I'm not sure you're talking about the flywheel either.

Can you explain what you're doing and how far you've gotten? Is this an automatic or a manual?

with the tranny out the flywheel is completely open? you should be able to sit straight up in there and hit em with an impact...i doubt you will get those off with a wrench they get pretty tight....what are you removing the flywheel for anyway? resurfacing it while its out? pilot bearing while its out, clutch ect.? there area ton of things you can do now while its all out and appart that will save you the huge headache of doing it again in a month

get that tranny all the way out sounds like its still hangin out in there...your gonna want to get an impact in there, to take em out and put em back in...

EDIT...the started is bolted to the tranny so it has to come out regardless...its not because of the flywheel

You have to remove the flywheel from the torque converter to drop the tranny. I am having a heck of a time removing the nuts off the bolts that come from the torque converter.

ohhhh automatic...wow we are one way different pages then

shouldnt the TQ be on the flywheel not the other way around? same place as a clutch right...and this is the first time ive ever heard of having to pul lthe TQ to get the tranny out? mind you i have never dealt much with automatics...manual FTW

do they appear to be a bit rusted in ? might want to try some good penetrating oil...not WD-40 that crap is only good for cleaning stuff

It's called a flexplate when you're talking about an automatic transmission.

I use a 6 point socket, about anything else i going to round off the nuts, then you will be a hell of a mess..

Find a GOOD 6 POINT socket, use a breaker bar, ratchet, with or without extensions to get to it.. Just be sure to get good and square to the nut...

There should be an inspection cover at the bottom, use this NOT the starter hole..

What could cause a fly wheel to break in these trucks, from what I've read its not uncommon, and mine is pretty beat up and not starting. Starter has already been tested good so threw inspection port was Abel to see flywheel is not sitting strait and grinding around teeth. So if I'm going be in there again after doing clutch 6 months ago what else could I replace to prevent it from happening again?

I've never heard of a flywheel breaking before. I would guess you didn't do something right when you replaced the clutch.

He has an auto trans, so it uses a flexplate (who the f'k came up with that name!?) which is thinner than a regular flywheel because the torque converter is so dang heavy it basically IS the flywheel. I've heard of them cracking before, but not sure why.

Normally when you pull an auto trans you take the nuts off the converter first and then slide the trans and converter out together. Reason being is that if you don't pull the trans STRAIGHT off the converter hub you can damage the pump seal in the trans.

I'd just get in there with a good box wrench and break 'em loose. Don't be afraid to put the torch to it if you have one... everything in that area is steel so you won't hurt a thing.

Did you have the flywheel off when you did the clutch work? If you did it probably didn't get bolted on square. When you install the next flywheel take care to snug all the bolts down even.

b_rasta brought up an old thread with a problem related to his truck. You're confusing it with the rest of this unrelated thread.

And this is why we start new threads instead of resurrecting years-old threads.
