Whole engine into frame? #781973 08/19/19 9:15 pm

I hope this is a simple question with a simple answer! Will a T150V engine complete with head & rockerboxes go into the frame without too much hassle? Or is it necessary (or just prudent) to do this with the head off?

I've never installed a complete engine. But once Conard Schultz and I were able to take one out of the frame.
Still, it would be much easier to do with the head off.

Do you turn green and your shirt rips off [aka the incredible Hulk]…..cos triple motors are bloody heavy buggers. I've done barrels on, but never rockers or head....only due to the weight and the ability to control that weight sufficiently enough to get it in without jamming a finger or gouging an engine case.

I did it years ago when I was a lot stronger. It fits, but my recollection is that it doesn't just drop into place. Be easier with either a hoist or a friend. Watch where the oil lines come out, and be prepared with some levers and alignment punches. If the frame has fresh paint on it, it more than likely will get scratched and need a touch up.

I just build the engine from the inside of a frame, but think it will be much easier to place an engine on it's side and put a frame on it.
Install a bottom bolt and a front one and turn it into standing position.
A frame, even with front end attached is much lighter than engine which weights a ton.

I am certainly planning to be using a friend to help with this! There won't be any gearbox or primary drive etc, so not maximum weight. It was bloody heavy getting it out with the head off, so maybe worth trying the engine on its side and fitting the frame over it technique? I was really wondering whether - ignoring the weight - there's sufficient space to fit the engine with the complete top end. It looks like there is, so maybe that's what I'll do (or maybe not!)

I have removed a complete engine in the past. I would not attempt it again. As I recall, it was difficult due to the weight and limited space.The last installation I did, the engine was installed with crankcases assembled and cylinder barrel installed. Without the gearbox, clutch, and primary drive, the weight was easily handled. I installed the cylinder block because that is much easier to do on the workbench.

Yes, this does seem like the most sensible method. My situation is that the engine is a long way from the rest of the bike and quite easy to completely assemble it out of the frame - which is tempting, as it's nice to see your engine sitting there complete!

But patience is a virtue, so I;m told, and I reckon I'll wait until I can put the bottom half & barrels in the frame before going further.

Thanks to all for your advice on this.
