Old pan rusted thru - new pan ordered.

I have read several post, is it possible to drop the pan, remove the oil tube and get the pan out without jacking the engine up?

NickBeek

I watched a dealer tech replace my oil pan gasket. He had to jack the engine up to clear the cross member that runs under the oil pan.

i would say that is mission impossible

take a look, the pan is almost touching the cross member.

Hope you don't mind me asking about this same thing in your posting.
I've been wanting to do the same thing, and don't think I've seen a post that said you could do it without lifting.
My question, I only have a floor jack and not sure if you can jack up on the crankshaft dampener (I've always called this a harmonic balancer?) I read on another posting about the dampener/balancer maybe part rubber and lifting by it might cause damage? Not sure if this was referencing another vehicle? Anyone know for certain it's okay to jack from below and what is the best way to go about it. Okay enough about my specific question.

All the instructions in the manual talk about disconnecting the transmission to change the pan. I am under the impression this could mean just loosening the transmission at its cross member not actually separating the engine from the transmission?
Also, anyone know of some specific instructions on what is exactly necessary to disconnect to allow the engine to be lifted some. Sorry OP, just very curious about changing my pan too, I'm sure you have the same questions.
Again sorry to jump in here like this, but was prompted to post since I haven't posted in a long time. Then again someone might come along and say we can do it without lifting and we're both golden. not holding my breath on that though. Thanks.

The instructions I read said to remove the starter, fan shroud and loosen the engine mounts. Not sure about the trans. The more information the better.

You will not get it off without lifting the engine, and there is another smaller crossmember (at least on an 06 there is) behind the pan. It has to come out down and back to come out. I was able to leave the tranny connected to the engine.

This is from ALLDATA for 4x4, 2005.

They show 4x4 and 4x2, some of the 4x4 install does not match up to the removal so please review and comment.

The 4x2 process looks like a lot more work, in additino it tells you to remove trans lines, propeller shaft, starter, torque converter bolts, exhaust hanger, gear shift cable, wire harness, trans mounts, bell housing, steering rack bolts.

Here is the 4x4 removal.
Disconnect Battery
Remove Air Intake Assy.
Remove Radiator Shroud Bolts.
Install Engine Support Fixture #8534B - Not sure what this is?
Raise and support vehicle.

Remove Dip Stick
Remove pan bolts and lower pan.
Remove suction tube and pan.
Remove the 2 bolts from the front of the engine block stiffener.

The Miller Engine Support Fixture #8534B is what the dealer techs use to keep the engine on several vehicle brands supported while they perform drive train related procedures. They are expensive braces.

The only way I have been able to get oil pan off was removing transmission. Remove the flexplate and extenion housing. You still need to loosen motor mount bolts and raise engine up some to get oil pickup off. There are four bolts on the pickup tube, then remove pickup with oil pan. Pickup tube gastket usually will stick to the block. Just don't forget to drain oil first.

rebal

you can get the pan off with out pulling the trans. I removed the fan ,took intake tube off loosened motor mounts then raised the frame up so the axle will drop to full extension then juck the engine up till its out of the mounts the pan will fall out with out removing the pick up tube . this is on an 2006 4x4 auto

Dynocon

How did you lift the engine?
On my 2005 the cross member is the obstruction so lowering the axle does not help, is the 2006 different

I used an engine hoist .but if yours is a 2wd your in for a lot more work


05 06 are the same 4x4 are easy to do just rase the truck up and unload the suspension then raise the engine up with a hoist /forklift /something , use the lifting eye at the tstat .raise it up till the heater hose tube almost touches the cab once you have the bolts loose it will fall out on the ground if you let it

Dynocon

I am still not sure how unloading the suspension helps, are you sliding the pan towards the back of the truck?

rebal

the pan drops out the back if you dont lift the truck the pan sump will hit the engine adapter and the axle not clearing the pick up tube it only needs a couple inches and it will slide in and out easly
