What does the 400 engine weigh without head & block ?

<< < (4/5) > >>

ka-ja:
Definately dropping the frame over the engine is the easy option, even easier without the forks fitted, but it really helps to fit the sump after fitting the engine.

McCabe-Thiele (Ted):
Yes I agree fitting the sump asap is a good idea to prevent possible damage & keep put contamination of any sort.

SeanFD:
To put my 400 engine back in, I put a couple of lengths of threaded rod through the mounting holes, and then myself and assistant simply picked it up and, with some bubble wrap around the frame, put it in. It was easy - sump and oil filter were off

The 750 was a different matter: involving some pulleys mounted on a home made “gantry”, a couple of webbing ties, and a different assistant. No pics sadly, but one of a later effort involving a 450K1 gives the general idea

That sounds nice & easy what size rod / thread did you use or was it garage left overs?
I threw all my steel offcut bits & bobs about 30 years ago!

K2-K6:
To protect frame finishes I've always used newspaper quite thick and wrapped round the tubes then secured with masking tape.  Very resistant to any contact, cheap and easy to slit the tape and pull out when installed.

For supporting an engine without work frame bolted to it, an old car tire is effective to sit it in any orientation.
