Feasible to pull engine/trans/case as one unit?

[urbex]

Began the teardown of the '85 K20 as the motor is going into the K5. K20 has a 454/SM465/208 combo in it now, and I'm not looking forward to dropping that stupid heavy transmission out the bottom. I'm pulling the core support out, so that I'll have a a more or less straight pull path out.

I have a load leveler if needed, and I was planning on hooking up on the chain as far back as possible to try to balance the whole thing, as well as finding someone else to help guide this whole mess out, but wasn't sure if this was going to be too much weight on the bolts that connect to the motor, or some other issue that I'm not thinking of.

i have done 2 drive line installs in my shop with the cab off and used 2 engine hoists to do the whole setup . . . thats a LOT of weight for a hoist .

lots of guys hold the trans / tcase threw the shifter hole or removable floor hump and then lower it with the hoist and slide it out . then pull the motor .

i can say for sure a full dress 454 is HEAVY ..

Only time I've attempted doing it that way was at the junkyard,with the cab off the frame--used the forkloader to lift all 3 at once..

You still risk breaking the transmission case with the transfer case hanging off the back,even with a 208 thats not as heavy as the cast iron ones...

A fully dressed 454 weighs at least 700 lbs by itself--transmission about 200 or so,transfer case about 80-100 lbs..most engine hoists will be extremely stressed and tippy with that much weight,and the rear wheels on it will want to come off the ground..

(Edit--Automatic transmission !--SM465 may weigh more--and the weight I listed for the transfer case is for aluminum ones--cast iron ones are heavy ingots !)..

I'd say take off the transfer case,its not that many bolts and pulling the tranny & engine as a unit is much more feasable ..it would be a cumbersome struggle to wrestle all 3 out together in a truck with the cab & nose on it..if it was even possible..

I dropped the last 465 off the trans jack taking it out from the bottom, and broke it. That's why I didn't want to do it again...guess I just got too spoiled wrenching on the Samurai, lol.

And that does what my dedicated trans jack doesn't.....how?

 

[AJs72K5]

I've pulled my fully dressed big block out with the transmission several times. Hoist does fine. But, yeah, it's a lot of weight swinging around. I do, however, drop the transfer case separately.

In the last drive-train removal I did I used my trans jack to remove my 205 transfer case first, and then used my engine hoist to remove the engine and trans together. I also removed the radiator support as well, in order to make it easier for the engine hoist to pull the engine and trans straight out.

Just trying to help, don't get snarky

My sincerest apologies. I hadn't realized I had somehow wandered into Pirate4x4, where asking for clarification is a panty twisting faux pas. I'll refrain from asking further questions.

Meh...I suppose dropping the 208 first isn't that big of a deal. I just have limited movement in one arm, so the less I have to do on my back under the truck, the better, lol. It was..uhh...interesting getting the trans and case in and out of my Samurai, and those things are light enough I can move them one handed. I just forsee attempting to maneuver a 465 around under the truck a good way to ensure I'll never move that arm again.

your coment come off a bit stiff as you never said you had a trans jack . he didnt know this and thats why he replyed the way he did .

simple boo boo is all . no one hurt .

ck5 is a lot nicer friendly guys than the pirate . but pirate does have some crazy builds also . i wonder on there from time to time .

Pretty sure I did...right there in post 5...

I thought hey maybe there's something about the adapters I was unaware of...not the first time a dedicated tool wasn't necessarily the best tool for a job.

I’ve heard of people removing the trans tunnel and using a cherry picker to lower/raise it feom inside the cab ... I think sweetk30 already mentioned that though.

lots of guys only read the first post before they coment . maybe thats were he missed it .

no biggy .

i even have a trans jack to use with my 2 post lift . if i was to pull lots of specific trans and t-case units i would be making specific blot on adapters to keep from having them floppy and possible drop .

Rigging a whole drivetrain to come out gracefully with the body on is going to be more complicated than figuring out how to properly use a trans jack.

Did I miss the part where you say why pulling the motor requires pulling the trans?

I have hoisted through the floor, I've hoisted the engine/trans as a single unit, and I've used a tranny jack. Hoisting them together was clumsy but it worked. Lifting through the trans tunnel was a good compromise when I was working on a loose sand surface. But the easiest trans job was when I found a level spot, threw down a piece of plywood, and made proper use of the tranny jack.
