Solo Engine Removal
« on: August 26, 2011, 12:49:52 PM »
I've seen a method on these forums and elsewhere, where you lay the bike on its side, and lift the frame to separate the engine. Can someone please breakdown the steps necessary to remove the engine this way?

I'd like to know which side to put the frame on, which components to be removed first, and in what order mounting bolts need to be removed(if it matters). Also, any other things to look out for would be very helpful.

Thanks in advance!

Just did this last night... Wicked fun bub..

remove all pertinent stuff,  i took off the chain cover on my 550, sprocket, chain, pegs, carbs, brake lever, disconnect electrical connectors at the starter solonoid, stator connectors.  Then remove motor mount bolts on the right side.  leave the 2 long bolts towards the back of the motor.  then do this...



Notice the tire cradling the motor at the head and base of the motor.  Then with some finagling and lifting you have this...

I usually set the engine on a milk crate next to the bike, then pick it up by the kickstart lever and whatever I can grab on the other side of the engine.  It is surprisingly easy to do (350/400/500).

I have also used two pieces of rebar through the engine mount holes along with an assistant to do the same thing.  I start with the engine on a milk crate next to the bike again.  The rebar allows full 3D controlled movement of the engine so you don't nick or even bump anything on the way in and out, and even a relatively weak person can be a helpful lifting partner in this manner.

I've done the whole thing with 3 straps from above... always hanging on with 2 straps moving them as needed.  Works well when alone.

500/550 are easy,the 750 is far heavier,i just remove or dont fit depending if its going in or out the alternator/rotor and starter,the oil filter housing,the pan and breather cover,then from the brake side i simply lift it in,or out,some 750 guys lay the frame over the engine etc,i dont think this is done with 500/550 unless you like to do it that way?

One end is secured in a tube welded to my workbench.  The other end has the straps as shown.  A wood extension is used to get my bike lift high enough.  This works for removal and installation with no drama.  More pictures and how to at KingCustomCycles.com

Alright so I tried lying the frame and engine down on the right side, removed the last two mount bolts the rear of the engine, and attempted to get the motor out.

This was such a PITA, and I didn't even get the engine out. Two items I didnt have were the tire to cradle, and I didn't remove the sprocket cover. Did these details contribute to my dificulty? The engine just kept getting Hung up, and I didn't have much room to wiggle the engine out of the frame.

Is there anything I can do to make this happen smoother?

It's a 73 cb750. Man this thing had me grunting, sweating, and cursing. I put it back up and on its side so many times its not even funny. Doesn't feel light at all, and it just kept getting hung up.

Try the trick I mentioned above using two pieces of rebar (or other suitable steel bars) and an assistant.  It is so easy to move the engine this way.  I really don't understand why people even bother laying the engine on its side and laying the frame over it.  The rebar trick gives total control so you really shouldn't contact the frame much at all (and definitely shouldn't nick the paint).  Plus, your grandmother could probably help you do it... if she is alive... if not, then God rest her soul.  ;-)
