Need New Flexplate. Pull Motor Out? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Branman1971 · 10-21-2013, 10:17 AM

I need to swap my flexplate in my 350sb/TH350 combo. I am considering pulling the entire motor and tranny and going through them. Not rebuild, but clean them up real good and repaint the block, new motormounts, new valve cover gaskets, tranny pan gasket, seal up the leaks. Has anyone pulled the motor and tranny out of one of these out as One Unit? I have pulled them before out of Fords still bolted together. Where should I get the flexplate from? I know there are many ones to consider depending on hp and such.Thanks!

MARTYZ · 10-21-2013, 06:53 PM

If I was doing all that I would just remove the front clip, only
take you about an hour tops, dozen bolts, two rad hoses and unplug some wires and everything is wide open and easy to access. Just my thoughts. Flexplate can be purchased at any auto parts supplier and can be replaced by just sliding trans back

Branman1971 · 10-22-2013, 11:30 PM

Now look what you made me do!

ChevyTruckGuy · 10-22-2013, 11:40 PM

lol.....Cool. I like the idea, now you can change out as many parts as possible on the motor while its out or when it does get out. Clean & maybe paint engine compartment ect.......Looks like fun.

donthekawguy · 10-23-2013, 12:56 AM

Pull it all! Clean paint update!

WhippinSaw · 10-23-2013, 09:03 AM

I prefer to pull the motor and tranny as a unit instead of just pulling the motor and propping up the tranny. Just use a bucket to catch the trans fluid that will leak out the drive shaft spline on the trans when lifting and tilting. Should be really easy with the front clip apart but not necessary. Enjoy

I like the under hood check list.

cg285 · 10-23-2013, 12:27 PM

if you are just replacing the flexplate it's a 30min job and nothing gets pulled

Branman1971 · 10-23-2013, 12:28 PM

Thanks for the help guys. I guess I will be pulling this thing myself because I have no friends. Lol. As for my check list it serves me well as a reminder because I can't remember anything. I've even got a reminder in on the left-hand side of the hood to love on my wife so she doesn't feel neglected for all the attention that I'm giving to "damn truck". I think that's going to be the name of my truck as it was affectionately named by my wife.

Branman1971 · 10-23-2013, 02:18 PM

Yeah, I'm sure I will be doing more than just the flexplate. So far I have planned:

Flexplate
clean up engine bay
valve cover gaskets
cap/rotor
plugs/wires
Tranny pan gasket
Tail shaft seal
Paint block
new headlight adjusters
Tranny crossmembers
re-run the wiring

So yeah, I wanna pull it out and get a good look at everything. I wish I had a sandblaster!

1963c-10 · 10-23-2013, 02:47 PM

If your going to pull the motor...id consider the rear main seal and an oil pan gasket too.

Branman1971 · 10-23-2013, 02:49 PM

Good Eyed Deer!

Hey Branman...
'63c-10 is right....
While ya have it out...change every external seal on the tranny and anything else you can think of.
Bench work is always more fun than "under-the-truck" work.

BTW: I really like yer "Damn Truck"...

A.T. RockDriller · 10-23-2013, 04:16 PM

Just so you know what you're up against...
This is what happened to me when I decided to swap my motor mounts.

Copied from Build Thread:
--------------------------------------------------------------------------------

Hey...Grease
Good ta see ya.....

I'm gettin my a$$ kicked on this one....
I'm just closing in on the motor mount swap....

Anyway.....
I'm down to finishing up the column.....and the attached shift linkage an...an...an..........and maybe that's it. Other'n boltin it back together..

I Gotta think 'bout that....Either way....I am ok to start it after I wire the engine harness....Oh. After I finish plumbing the aux. fuel tank (so it will be the only tank) because I yarded the one out from behind the seat....Just have to bend the rest of the tubing....I'll take a pic later.

Anyway, here's a couple for ya...

1963c-10 · 10-23-2013, 04:46 PM

Nice work Les....your truck is coming along real nice.

Branman1971 · 10-23-2013, 05:33 PM

Yeah Les, she's a beauty! I have some floorboard spots that need some help too. How did you clean up your frame? Sandblast?

par4tom · 10-23-2013, 06:37 PM

Nice looking project. But beware...

These types of projects are addicting...start with just a flexplate change and the next thing you know you've got a new engine, new paint, new upholstery, new everything!!!

Ask me how I know...sigh!

Branman1971 · 10-24-2013, 10:09 PM

Ad here we go!

MARTYZ · 10-25-2013, 08:36 AM

Well that's the cheap part done now how much are you going to spend is the question or the challenge,

Nice work and good looking truck !!

Branman1971 · 11-10-2013, 10:46 PM

Getting there.

61_FL_Apache · 11-11-2013, 08:22 PM

See that was easy!!!

Branman1971 · 11-12-2013, 06:15 PM

Got these done. Now to clean up the engine bay and firewall. The firewall looks like Swiss cheese with all the mystery holes drilled into it. Thank god for welders.
