i'm sorry for being slow on the drawings and measurements. but im having some trouble with the engine.
while dismantling the cam holders, the treads came out with one of the bolts. PO must have tightened them down too much.
Also, I never thought it would be THIS hard to get a helicoil kit in a reasonably developed country as Norway. the city closest to me has almost 100k inhabitants. But not a single hardware store had any in stock. the closest i got to a kit was a special order for a full kit, which would have set me back 650$.
anyway, here are some more pictures and some quick measurements. I didnt have a angle measurement tool at hand for the bends. When i made it i just bent them at apropriate places.
Measurement C = 11cm / 4,33 inches, and the upper eye nut is 8cm/3,14inches from the end of the bend
Measurement B = 14cm / 5,51 inches
measurement A = 11cm / 4,33 inches, and the lower eye nut is placed at 9,5cm/3,7 inches from the end of the bend.
in this picture the engine is actually hanging about 25cm (10 inches for you americans) above the floor, and the engine is quite stable
the design of this "jig" isnt that important. you just have to find something that you can bend into a C shape. that will hold about 100kg. just make sure it will get around the frame over the engine.
