Tech: How to pull a motor (short version).

I helped a friend pull the motor out of his 1971 Chevy Camaro today. He had never done it before, and I have lost count of how many I have done, so I was official advisor. I let him do all the work so he'd have the pride of accomplishment. This is a very simplified version of what to do. It's actually not too difficult. My friend already had the motor ready to come out. Disconnect all the accessories, exhaust, intake, fuel line, radiator, belts, wiring (labelling all the wires), hood off, etc. Take out the front motor mount through bolts. It is not necessary to remove the intake manifold, as he has done here, but he will be swapping it to the new motor later anyway. If you're going to use a chain across the top, like we are, remove the valve covers. Drain as much coolant as you can.

Other side, you can see the exhaust headers are off and out of the car. Roomy in there now.

Get underneath, and disconnect the torque converter to flexplate bolts. There are three of them. This is kind of a tough part. It goes way easier if you remove the spark plugs and have the nice flexplate turning tool, which I gladly lent. Push the converter back into the transmission as far as it will go; about 3/8".
Support the transmission from underneath with a floor jack and a block of wood, like so. Nothing fancy here; block of wood.

Attach a hydraulic hoist, and begin lifting the motor up. You can see how we used a chain across the top of the motor. The motor will tilt up about 2" in the front, then pull it forward about 1" and it will pull free from the transmission. Boop!

I'd rather see this than a dead deer on a hook any day. The hot-rodder and his daughter pose with the removed motor. It is, in a sense, that easy.
Perhaps I'll do a follow up on the reinstallation, highlighting one or two things to watch out for. It's only marginally more difficult to put a motor back in.
Thanks for tuning in.

Pretty cool. Nice rebel flag.
