Its almost time to wrestle the rebuilt hornet engine back where it belongs! Any advice on the best way to approach it? I have a strong assistant but no hoist. We'll be working at ground level. Ive left barrels and clutch off to save weight. Would it be wise to fit oil union before or after installation? Any thoughts gratefully recieved. Thanks Dave.
normally bottom oil pipe connector fitted pre install., Ive read on here some try fitting the engine with the frame on its side, personally, Ive got pipe insulation for the bottom rails and front down tubes to prevent scratching new paint , maybe thin plywood on the bottom rails to help slide in, but would be in the wayof lower parts that drop below frame.
Im still a glutton for punishment, barrels and head on, maybe why my back is so bad..
Hi,
If you search the Forum you will find some previous threads on this topic. For me it is to have as little as possible on the cases to keep the weight down and follow the instructions in the workshop manual. Page B17 if I remember correctly.
The manual refers to a complete engine but unless you have a very secure engine stand getting the crank and clutch nuts torqued up is easier in the frame. You only need to concentrate on getting things tight rather trying to hold an engine still at the same time.
It is easier to have the oil union fitted unless you have the proper bolt with the thin head as this will just go in with the engine in the frame.
Like Chaz, I have used pipe insulation on the frame tubes but rags wrapped around will do the job.

If you are able, put the frame over the engine..
Lay the engine on the clutch side and prop it in position, then carefully lower the frame over.

If its already a rolling frame then this is most likely not possible.

+1 for installing the engine with as little as possible attached ie just the cases with the crank fitted. Still a bit of weight in that alone. You can then build up the engine and if you have a bike lift it makes it so much more comfortable to rebuild the engine. ( I think the whole engine weighs around 72 kg).
I believe in the factory the engine was installed complete by tying a rope around the barrels and lifting and swinging it into position.
Up to you regarding the oil feed pipes. They are a lot easier to install with the engine out of the bike especially if you have an early feed which requires the gasket to be fitted as well. The later "O" ring pipes are a bit easier to fit especially in the frame. If you do fit out of the frame, just be careful you dont knock them or damage them when refitting the engine. The correct thin headed bolt allows the pipes to be fitted in the frame.
Good luck!
Thanks all. Your the best! Dave
