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 offThe 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 (Attachment Link)
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!
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.
Here's how I put it back into the frame Ted. Engine on the floor and lifted the frame over it. I put a couple of engine bolts in and put the sump on followed by the wheels and just lifted it up, nice and easy.
