Otto. If its anything like a small journal to fit, it will be like a metal puzzle from a Christmas Cracker. It will only go on one way, and then only when either pressed on or heated to expand and probably also need a bit of a smack to line things up.
Recent ebay purchase was a SJ crank with the flywheel held on with 8mm soft nuts and bolts. Never having disturbed a flywheel before this was too good to miss and once unbolted began the Houdini trick. It was not easy, there is a definite knack with the positioning of the flywheel to pass over the big end and crank web. This crank needs grinding, and although it can be ground with the flywheel in place, I'll reassemble after machining. A nice protective tape wrap on the big end journals will be a must. For your crank I reckon a bit of practice cold should lead the way, then another big heat up and fingers crossed it fits.
Any thoughts on new fixings for my crank. Originals were BSF? but High Tensile UNF are more readily available and are a finer thread. Downside is they come in packs of 10! Also used the oven trick today to ensure less violent removal of big end bolts from an A7 rod. Er, well, they did need just a little extra smack with a wooden block......
