Better to remove engine or eng/tranny?
I keep getting conflicting advice about whether it is better to remove just the engine or the engine/tranny together. Which do you think is better and why?

You can ask again and still get conflicting answers. For the first time, I'd recommend removing as a unit. Thereafter, you can decide your favorite procedure.

My first time I removed both the engine and trans as a unit. After countless searches this looked like the way to go for a rookie. Its really not a great deal of extra work.

I'd recommend as a unit- much more stable. Just double and triple check you've disconnected everything first! I was able to do it myself with very little assistance from my father-in-law.

I have pulled my engine and put it back in by myself twice, both times without the tranny. I am not saying it is better, it's just the way i do it.
Lining the two up during re-assembly can be a PITA but if you pull the starter completely out and look through the hole it makes it much easier to line up the throwout arm etc. |

Thats what I was thinking, that if the engine is removed by itself putting it back would be hard because of the difficulty in lining it up with the tranny.

When I did my rebuild I pulled the engine alone thinking it would be easier to handle by myself. Then I removed the transmission and reinstalled as a unit. Don't have the experience to say one is better but this worked for me. Used the ATV jack to remove the engine alone which was definantly a stable platform.

One benefit of removing them as a pair is so that the inner CV joints and bolts get looked at.
Two of my bolts were badly stretched and neede replacement. If I had dropped just the engine as I have done in the past, these bolts would have failed and left me on the side of the road. I found that when re-installing the pair, the front (trans) mounts were difficult to line up. If you just barely connect the rear (motor) mounts and then start the trans mounts bolts, it's much easier. Then make sure everything is tight. Make a check list if necessary. And....have fun....after all...you could be working on you uncles old tractor! ....LOL Bob

We pull the engine and trans together when the trans needs rtepair. If repairing the engine is the goal we pull the engine alone.

I generally work alone with one jack. I couldn't imagine installing the engine without the trans under those circumstances. droping, no sweat gravity is on your side and everything tends to want to fall apart, but going back in is another story.

Does anyone have a picture of the tranny mounts? I don't know where they are and how many there are.

I do it either way. Each has it's own PITA procedures...

What is PITA? Thanks for the diagram! Shoud the tranny be disconnected where the support meets the tranny or where the tranny meets the frame?

Pain In The Ass.
You remove the number 8 bolt in the diagram. I have only done one drop and I droped as a unit, it was pretty easy. I guess its a little more work removing the cv-joints but its not hard...

Do you disconnect the tranny mounts before the engine mounts?

If you take the trans out with the engine, disconnect the trans bolts first and the package will be supported by the nose cone of the trans. Then as you lower the engine pull back on the lump and the nose cone will clear the hole.
Balancing the lump will prove to be the greatest challenge.

PITA? Well maybe an exageration...
Disconnect them with the trans remaining in the car means a tougher time lining up the clutch fork. Disconnect together and you have to wrestle with a larger unit and disconnect all the CV bolts and risk tearing the CV-joint gaskets...

"sO WHAT DO YOU RECOMMEND?" Don, We could continue this conversation ad infinitum, but I doubt everyone will agree there's just one way to do it. That's because ..... there's more than one way to do it. You'll just have to decide to remove either one large hunk or one slightly smaller hunk. So get busy and let us know which way you prefer.
