What does the 400 engine weigh without head & block ?
Nurse Julie:
Great work Ted. On the subject of lifting engines, you would never see anything as funny as Trig and myself lifting fully assembled CB750/4 engines. I really do use every scrap of strength I can muster to help take the weight but my goodness, they are heavy. Trig always has a little energy left though to shout at me telling me I'm not holding it right and I'm going to drop it 🙄🙄🙄

Did they? There's not enough room with the sump on and breather cover, oil filter fitted.

On the 750's I've built, I've managed to lift the engine off the bench on to progressiveiey lower (by a foot lower at a time) until lower frame level onto a blocked wooded platform, put plastic plumbing pipe (cut in half) taped to frame rails to protect the paint, shimmy engine partly into frame, then leaned over frame (resting chest on upper frame) and lift and manoeuvre engine into position - my assistant (Mrs Ward) then pokes the bolts into engine.
Taking the engine out the same but used a tolley jack to do the lifting as high as possible (non back breaking height wereby I can use leg strength) to then manually lift to the bench.
Heavy but managable. 40 years of daily press ups/chin ups/running has probably helped!

Here's how I put it back into the frame Ted. Engine on the floor and lifted the frame over it. I put a couple of engine bolts in and put the sump on followed by the wheels and just lifted it up, nice and easy.
Bryanj:
I had a "factory" picture years ago but lost it in one of my moves, sure it showed the engine as a lump but i an old now and Guinness doesnt do the brain cells at lot of good!!@
