:confused: Can it be done? 79 K5, 350/350/NP203. I am working on it today. I would appreciate any advise I can get. I dont want to drop the drivetrain if I dont have to. The old flywheel has a worn spot so flat I cant get one clean revolution to start it up anymore. It's been a long time coming. :o
 
I have been out there removing the flywheel bolts. I can barely get the wrench in to them. Is it possible to drop the transfer case cross member and back out the tranny bolts a bit? Would this be a waiste of time? Thanks.
 
I don't understand what you are trying to say.

Now that I think about it, I bet you have an auto and are calling your flexplate a flywheel.

I am unsure about flexplates (my truck's a 4 speed) but I think you can remove them without dropping the tranny/t-case.
 
Yes, I have an automatic TH350 transmission. I did not know the differance between a flexplate and a flywheel. Now I do, thank you. Flywheel=Standard Flexplate=Automatic...got it.
Now, does anyone know if it can be done?
 
Run some 4" long bolts into the back of the motor through the bellhousing, then you can shimmy it back on the long bolts and hopefully get enough room to pull the flex plate...providing the bell doesn't hit the firewall first. You could also drop the tranny crossmember and lower the rear of the tranny for a bit more firewall clearance.

Personally i'd just drop the whole thing though.

The tranny will have to move backwards enough for you to unbolt the flexplate and remove it then to re-install the new one. You don't have to take the tranny out but just unbolt it and slide it backwards.
 
Okay, thanks. Im halfway there. I have two more bolts in the tranny, then I'll drop the crossmember to allow it to slide back. I hope I don't have to do this again for a while! Thank you for your help.
 
Okay, here is a stupid question. I cant find a picture or an answer in my aftermarket repair manual. Which direction does the flexplate bolt on? The one I took off had the deeper "dish" toward the engine. Just looking at it, it seems like it should go the other way. There is a slight flare to the center opening. Which way does the flare face?The guy who put the thing on originally didnt know what he was doing, so I have to question the way its installed and dont dare take for granted that its correct.
 
Mine has bumps where the torque conver bolts to, so the bumps go towards the trans.
 
Rene,
Your method worked beautifuly. I finished up last night. I couldnt really drop the tranny because of where the truck was. Thanks for your help!
 
did you have space to get a torque wrench up in there? seems like it would be tight even with the extended bolts.

No, I torqued them to 3-4 grunt pounds each. Only enough room for a couple fingers or a open end wrench.

I've done this a couple of times. :D
I also had to take off a torque convertor off a seized engine, now that was a bitch :o
