How to move an engine?

What I need to do: Move the engine 1/2 an inch

Why: After replacing the motor mounts, I lowered the engine down onto the new mounts, only to find that the holes for the center bolts that hold the mounts to the engine no longer line up. They are about 1/4 to 1/2 an inch off.

What I have tried: Jacking up the engine in different places, trying by hand to push the engine (then with a friend) and then with a friend with the engine jacked up. Did it move? not really I just don't want to try something "drastic" and end up breaking something. Any ideas on how to do this safely?

And if it matters, my car is an 84 300d

Thanks!

I guess tenacity is key. Just wondering, why is jacking up from the oil pan a bad idea? seems every thread on changing the motor mounts says to do exactly that.

put a block of wood under the jack to not put a hole in the pan.

Yep.

I just lowered my engine and trans back in this evening and it lined up with one motor mount bolt hole....so I put in that bolt. Then I lifted the engine enough to be able to slide it on the other mount until it lined up, then I put in that bolt.

Engine cranes rock! (I bought a harbor freight one a couple weeks ago for my recent project....can never have too many tools.)

You don't have an adequate collection of tools until you have a lady foot bar and a few various line up tools and pry bars.

I think it was Galileo that said "show me where to put my lever and I will lift the world." In the case of working on machinery, there are MANY places to put the pry bar that will move whatever you want to move. The key is placing it where it will get the job done AND not do any damage.

I use various chunks and lengths of wood as pry bars, they work quite well!

Yes, there is a lot to be said for using a 2X4 for certain things. Things that otherwise might be damaged by an iron bar will be saved thanks to the sacrifice of the pliable wood.

After several hours, and several bloody knuckles, I have finally moved it. I used a board while under the vehicle, and finally moved it the 1/2" I needed. Thanks for helping me all.

I never would have guessed that I could move the engine so relatively easily with a two foot board. It just took some time.

Allowing some latitude for translation, that quote was attributed to Archimedes, who died around 1800 years before Galileo was born.

Tangofox says "Do only one motor mount at a time and you won't need to move the world."

Well it's been about that many years since I had my World History. Along about 1961 to be exact. At my age I'm pretty proud that I could at least paraphrase the quote, never mind that I missed the name of the person that said it.

Acouple years ago JIMMYJO came over with his 78 300CD we replaced the mounts, and only one lined up. put the bolt in loose, raised the engine a little and used some prying, and that thing would not line up.

so I tightened the one bolt down, and told him to run it down the hill and back. I live on a bumpy hilly, curvy county road. when he got back, it was lined up.

very nice job Larry,
for those anal types with the need for the exact quote...
“Give me a lever long enough and a fulcrum on which to place it, and I shall move the world.”
and yes, it was Archimedes
