I'm about to do a 4.0 long block swap. Are there any good threads out there on removing the engine from the transmission? Or any on reinstall?

Thanks

 

It's pretty straight forward, I just did the a Long Block swap, I'd pull the engine and tranny together it just makes getting to the bolts easier, I have some striped bolts on the top of the bell housing, Just unhook everything and take out all the bolts. then do the process in reverse

 

+ 1 just did one...those tranny bolts are a MFer....take both out

 

Absolutely not necessary to remove the whole thing. One of the easiest engines to pull I've ever done.
Remove the radiator is all you need to do up front. When unbolting the trans from the engine, remove, or at least loosen, the upper two bolts FIRST. They are E-12 heads. Support the front of the trans with a ratchet strap or floorjack.

 

Any special way to put the Cam Position Sensor into the new block?

 

When I did mine I pulled the intake and header before the motor. I found out that with those out I could reach the E 12 bolts from the top with an off set box end wrench. Was an easy swap.

 

I always pull the manifolds first when removing the engine and install them before putting it back in.

 

How did you get the bell housing bolts back in with the manifolds on?? That seems impossible unless you dropped the tranny a bit and got it from the back... hmmmmm

 

I had the frame side motor mount towers out already so when we dropped the motor in I got the lower bell housing bolts in then lowered the motor tipping it forward away from the firewall.
This was my first Cherokee swap, so not sure if that was easier than dropping the tranny some, but it worked. Had the manifolds on when we dropped it in.

 

Well I'll give it a shot with the manifolds on because those are a b**** to torque correctly when the motor is in the truck.

 

Assuming you have a 00/01.

When I rebuilt the 4.0 in my TJ, I set cylinder 1 to TDC on the power stroke and pulled the cam sensor. I marked the cam sensors gear position and set it aside. The fresh block came back from machine shop and I simply did the same thing for installation. #1 TDC on the power stroke and installed the cam sensor. It started and ran fine, but I did take it to the dealer to get it set/calibrated.

 

i think my 4.0 is starting to knock. (yes i have oil in it) i dont really have the place to swap in a new one myself. i was wondering if any of yall had a garage do a swap and how much it cost.

 

It was in my case, they were already stripped from the guy before me. Only way to get them off was to cut.

 

Those Torx bolts were a PITA! Swaps done. Buttoning her up today.
