Separate pulling engine motor from tranny transmission -any ideas?

(long title for future search purposes)

I sold my 3.0 engine and spent all day today helping the guy that bought it disconnect everything to pull it out. We disconnected all the wiring, hoses, cables, starter, A/C, P/S, exhaust, etc.
ALL the bolts connecting the 5 speed tranny to the engine were taken out.

Well finally about 11:30pm we hooked the motor to the engine hoist and it won't budge. No matter what we did, it just wont separate. We even jacked the tranny up and then tried...still nothing. We used pry bars between the two, nothing. It natually separates a good 1-2 inches but it will not separate completely. We spent almost 2 hours trying everything untill he finally called it quits. I even had two other guys pulling back on the hoist, motor, shaking it, etc. but no matter what we tried, it wont bust loose. The transmission has been in 1st gear and neutral but that don't seem to make a difference. I can raise the engine a good 6-8 inches but the tranny comes up with it. I can't go any further because things start to crush the firewall.

My knuckles are bloody, hands are greasy, got elbow rash, dirty clothes, but i'm still determined to get-r-done. Is there something i could be missing thats internal or just don't know about? Is there a "trick" to it?

if you are gonna pull the engine but not the trans you have to make sure there is no bending force between them so having the engine hoisted way up over its normal operating height isnt helping you. Any bending binds up the input shaft splines with the clutch pack. Keep it as low as possible even if it means you have to pull out the radiator to keep from bashing it. Once you get the input shaft out of the clutch pack THEN you can start lifting it up.

sounds to me like you missed a bolt.... when we did my 5speed on the truck the 2 came apart with little to no effort.

I suppose you could have had the pilot bearing sease up on the input shaft which might cause some problems.

its not that big of a deal to just pull both at the same time then wrestle it apart on the garage floor.

I'm voting for the input shaft being seized to the pilot too. It isn't common, but that seems to be the popular problem if I'm having trouble separating an engine and trans. You should have 6x 17mm headed bolts and 4x 14mm headed bolts, BTW.

what would that have to do with it? Torque converter just slips onto the input shaft of the A340 just like the clutch does on the R150.....

he listed starter as something he disconnected. READ before you answer. He clearly states that it is a 5 speed. People are thowing out random stuff that doesnt pertain to this. BTW i have no clue wut it might be.

one could easly read the above as disconnecting the WIRING for the starter... but not taking the starter out!

prob missed bolt, thats what I missed, everyone was yelling and pissed cause there was no budge. I then checked the bolts my buddies took out, one missing.... that was the problem

If yo ustill cant get it, put like a rope in the 2 inch slot and have it come out both sides, and have 2 buddies pull each side whille pulling the jack stand, I duno thoug it should come out though,, good luck

Make sure you have ALL of the bolts. There is one on the VERY top of the bellhousing that is almost impossible to see/get to. If you sit in the driver-side fenderwell and look at the top of the bellhousing you can see it. To get to it, you have to sit in the fenderwell and reach in with a ratchet which isnt easy. Once you have all of the bolts, it is still a pain in the ass to get it apart, but just keep wrestling it and prying with pry bars... It will come apart. It took me one night of wrestling it, then a good 3 hours the following day.

Here is a pic of the bellhousing to show you the orientation of the bolts:

This makes it easier yes, but you still have to reach up between the engine and the firewall which is a tight fit. Also remember that the exhaust crossover runs back there as well, and drops down on the driver-side.

Well thanks for all the replies. It turned out to be the input shaft/pilot bearing was hung up. We finally got it separated with the help of daylight and a pry bar being better placed. It then came right apart. I still can't believe how stubborn it was last night...EVERYTHING was disconnected or removed that needed to be including the starter.

FYI: Since the 4runner is totaled, i kinda cheated by cutting (sawzall) a section out of the inner fender wall to get to one of the top bolts on the tranny. Having a 1" BL helped a lot too. Thanks again.

It's alot easier if you place a scissor jack or hydraulic jack and woodblock under the bottom of the bellhousing and take the weight of the transmission off of the engine. Without doing this, most of the weight of the transmission and transfer is supported by the input shaft which in turn is supported by the clutch disc. Trying to pull the motor without supporting the transmission would definately be a wrestling match

Good advice but... we did exactly that to no avail.
We spent a good an hour and a half doing everything you could possibly imagine. We rocked, pulled, tugged, shook, raised, lifted, supported, pried, kicked, and cursed the motor, tranny, and the hoist in so many different variations that anything more would of been pointless.
Like i said, the next day (even though we had 3 lights) it simply decided to come apart with nothing more than the help of daylight and a prybar.

I still find it puzzling at how stubborn it was in the beginning...it had a 1-2" of seperaration during the whole ordeal but it just wouldn't come apart. The next day, it did.

I just wanted to point that out for anyone that experiences the same.
