 |
|
I'm trying to figure out the best approach to removing my engine by myself. I am planning on using a block and tackle to lower the engine onto a dolly. The cloudy part is whether to remove the AT tranny with the engine or to separate the two in place and then drop the engine.
I am planning on leaving everything on the engine, including the exhaust system - it will need to be cut off. Not sure if that helps push the decision one way or the other.

Whatever method you use remember to unbolt the converter from the flexplate before separating the engine from the trans.

Yeah, I resemble that mistake...10,000 or so miles later, I feel like I can say bullet dodged, but don't do that.

dabaron- also, if you only drop the engine, remember to support the trans well, definitely don't want it hanging from CV's or moving around too much, makes it harder to line everything back up.
That said, next time I have to take the engine out, I'll also be dropping the auto and taking it to a local shop that still rebuilds them, has great rep, etc. Wish I'd done that the first time just so that it was done.

Problem arises when you bend the tiny pump axle that runs down the drive line between the transaxle and the torque converter. It is hidden, and slides out a bit with the TC as you try to pull the engine away. So, while struggling to bring it all down just a little, there is a huge weight on that tiny shaft. Bends like butter. Also, I have done it successfully with leaving the transaxle in, but it was just plain unwise. I only got lucky, to have seen up close and personal what a bent pump shaft looks like, and the adventure of finding a replacement. This was my only savior when doing it myself. I am 100% sure I would have messed it up if having not seen it happen to my Pal.
The skinny here is that you take the bolts off the trans side of the axles, and then its like another bolt or two to pull, and the Auto will come down and slide out with the engine. If I ever run into this situation again, I will insist on dropping the whole thing together. I totally agree that getting it out without damage is only about 1/4 the difficulty in the whole R&R, as the put-back-in is about 400% harder with engine only method.

ok, so the tranny is coming out with the engine... thanks for steering me in the right direction.
i'm thinking this would be a good time to move from the factory AT cooler since it will be apart.

don't forget to undo thebottom 2 engine to trans nuts 1st
it's much easier then when the engine-trans is on a cart

Once I remove the 3 torque convertor bolts, I like to slide the torque convertor back slightly and verify it rotates back and forth independent of the flex plate. The nose of the torque convertor can stick and make a big mess if the torque convertor does not remain in the automatic when you separate. A long tie rap or piece of coat hanger through the cooling vane and secured to the bellhousing through one of the cast vent holes will ensure the torque convertor stays put till you are ready to remove it.

having a hard time following, looking for some pictures to help me understand. i find plenty of the TC, but how and what it is attached to eludes me. i see the 3 bolts on the TC, but not where they go.
EDIT: this thread helps me understand a bit better

i found no recommendation for removing the transmission with the engine, regardless of type.

Yep. Bentley does not cover that. It assumes you have all the tools and lifts necessary to do it either way.
It does not know what a floor jack or ATV jack is.....
That is where forums like this are invaluable. Folks here can help tell how to do repairs with regular garage tools.
