What does the 400 engine weigh without head & block ?
« on: February 05, 2021, 11:40:51 AM »
My brother is visiting me in the morning to help me lift out the engine - it will be more a case of him lifting with me directing the process.

I am wondering does anyone know the approximate weight of the engine minus the sump, head & block ?

I don't know the precise weight Ted but if it helps, I can just about pick it up on my own but I wouldn't want to carry it too far 😁😁😁😁

A complete engine weighs just under 60 kilo's

I lifted the Kawasaki Z400 engine out on my own a couple of weeks ago. The head and barrels were removed along with the sump, starter motor and clutch. It was still heavy but manageable on my own just a bit awkward lifting it out. It's a lot easier lifting the engine out of a frame that's going to be repainted, it's something else putting it back into a newly painted frame on your own!

I weighed one without the top end recently to work out the carriage charge Ted. 😉

It was approximately 35kg, noticeably easier to lift than the whole lump.

I most certainly couldn't lift a complete engine on my own. But as I said previously, I can just about lift a bottom end so it sounds like 35kg is my absolute limit 😊😊😊

engine out on a NJ engine mount by Macabe Thiele, on Flickr


My brother (Paul) came over to visit this morning - we two handed the engine lift initially me on the left side he on the right.
Momentarily rested the engine on the frame when it was 90% out - this enabled Paul to move his grip for the lift out onto a slab of Kinspan.
I think I had overthought the weight & difficulty. I did casually mention that NJ could lift an engine out unaided so this spurned him on.lol

Can you refit the engine with the sump attached but without cylinder head?

No. Sump has to stay off.
The weight I quoted was without clutch, alternator and starter motor!! Well done getting it out. Onwards and upwards now, subject to 'the boss' of course. 👍

You can refit the engine complete, Honda did on the line, its just easier to fit only the bottom half as the top will build in the frame

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.
