It's what I followed the first time I took my Thundercat engine out.
I've lost your number by the way because I'm a tool so drop me a text and we'll sort something out if you want some help, it's not the weight of the engine it's the shape that's the killer, I got mine in and out of the boot of a Yaris on my own but to drop it out and put it back in the frame I'd say you want two or three people. You really want someone on the jack, someone taking the weight of the engine and another watching so they can spot if you've forgotten to undo anything and to tell the Jack person to stop.
Oh, I have a rattle gun too that will probably come in handy
; ) Especially on the nut holding the rotor on
