Topic: Engine removal?

[rachsrib]

I think I need a top end rebuild on my cb750 and I think the engine needs to come out to do that but, I dont have one of those fancy engine winches to lift it out.  What are some other safe options for removing the engine if I cant get a hold of one.  A friend told me it would be too heavy just to hand lift it out.
Thanks

You can lay the bike onto its right side and pull the frame up and away from the engine. Most people remove and install it in this fashion. I did just this fall/spring.

One of the posters here had an engine hoist with a chain and a beam. One end of the beam attaches to the motor, the other end has weights to match the motor. The chain goes in the middle

Here's a visual from an earlier thread.

remove all bolts.

tilt to one side.

shake firmly and vigourously until engine falls out.

(it is a little simplified but you get the idea).

If  you have a couple of friends you do not need to tear the bike down to the bare frame. You will need to remove the fuel tank, the side covers, and anything else that might shake loose (pun intended).

1. Remove tank and seat.
2. Remove carbs,exhaust and oil lines.
3. Unplug all electrical connections
4. Remove all engine mounting hardware
5. Place stout milk crate next to bike, on right side.
6. Lay on top of frame
7. Lift and rock motor out of frame, towards the right side, onto milk crate.
8. Installation reverse of removal.

Thanks I like the idea of laying down and shaking think I can manage that.

Dont forget to remove the breather cover on top of the valve cover. The engine will come out a lot easier.

Just did it last weekend.  Not that bad.

Do not remove all the bolts, you gotta leave the two rear ones in and pull them once you tip the bike.

Make sure you got something on the ground to catch the oil that will come out.

And with two people you can leave a lot on the frame. 

Use Jack stands and a jack to help raise the frame while your jiggling the engine around.  Especially if you don't do a full tear down to the frame.  You'll need to take a brake from lifting and we used the jacks stands to avoiding losing the progress we made.

Here's what you hope to have when your done...

Can you do the 'lay it over' method with the pegs/handlebars still on the bike?

btw... any appx. idea of the engine weight with the top end removed? (mines a 550 though)

boxnife, look at my pics above.  The handlebars are still on.  I removed the pegs though.
