Engine/Transmission Weight?

Post by GeorgeP1111 » Mon Sep 06, 2010 3:33 pm

I'm thinking about dropping the motor out of my '68 CA77 Dream this winter and was trying to find out just how much the engine/transmission package weighs.

I did do a search and found some comments about it being heavy but I have not found anyone that listed a actual weight. The Owners Manual lists 373lbs for the dry weight of the whole bike so I would expect the engine/transmission to be at least 150lbs.

Anyone know?

tnx
George

Hi,

Engine weights around 58 Kg (CB72).
Crank, rotor, head and starter are the main weight.

Don't try to lift it alone, or if you have to, get rid of the starter, oil, rotor and stator.

A CB450 engine is even worse,

Great, thanks for the weight. 58kg = about 128lbs. That should be close to what my CA77 should weigh. Yup.... I won't be lifting it alone :-)

tnx

haha !

And now you tell me !

I lifted it of a stair's !
2 steps down, I thought.. this isn't going to work, I lost my control of my right leg, the other leg is reinforced with a piece of steel attatched to the bone, with happend 8 months before.
So with all my strengt I went the stair's up again, then, I putted the engine on the groud, And putted it in a wooden box, and with box and all, draging over the stair's, I went down.

Don't ask me how much I was sweating.. With my freshed-up motor, wich took me a long time.. and all my effort...

haha, I still gotta laugh and still get the nerve's when I think of that moment...

In my vision I see a beatiful CB77 engine rolling of the stairs o_O

CB72, without starter motor, is fairly easy to lift and carry. Just be very careful with your back and no oily floors or kids running around. It's easier if you have an engine stand to grab and steady it by.

I just lifted a GT750 motor and that baby was HEAVY. I think that GT barrels weigh about as much as a complete CB motor.....

Yeah, I can empathize with all the grunting going on here. Last winter I brought an S90 back to life and was it an absolute joy to work on. I actually took everything off the chassis including the engine, and then carried the chassis and engine into the basement to work on it over the winter months. I assembled the motor back into the frame in the basement and brought it back up those stairs as an assembly, grinning from ear to ear all the while.

I've done the same with a HD Superglide engine and frame only they were assebled together for both the down and back up trips. Only difference is I slid it down a board laid over the stairs. If you have to go up or down with a heavy load, I would suggest using a board because it provides sufficient friction to hold the load while you rest a bit and gives you more control. Even if you have to let it go, it will more than likely slide slowly down the board to where you want it with little consequenc.

I would also suggest you go out to buy a hand truck for moving heavy stuff, including moving stuff up and down stairs . I would not be without one. I think if Isaac Newton had lived a little longer, his famous quote might have been, "Give me a hand truck and I'll move the Earth." I put 140 feet of dock in by myself every summer with one and moved a 10 foot wood picnic table by myself with one. One of the handiest tools you can have around the shop/house.

You can buy a decent one for about $30.
regards,
Rob

Ok, now I can add to my own posting.

My '68 (aka '67) CA77 305 engine with L & R Case Covers, Kick Starter, Electric Starter, and Gear Shift Lever installed (no oil), weighs in at 122.3 lbs as measured on my old style medical (balance sliding weight) scale.

Too heavy for me to manage by myself but easy with another. Once on the bench it's easy to move.

I'll be starting the engine/transmission rebuild this winter so Stay Tuned for a load of questions :-)

George
