Thanks "Veebyes"
"do recall something about beating the you know what out of it before discovering a circlip that has to be removed & the spring pin through the bevel gear."
I have removed one "C" clip. It released the gear box (reduction gear) which separated from the gear tubes. I now have an inner and outer tube with the bevel gear/screw inside. The schematic shows the pin I think you are speaking of, but its under the gear head and I can not access it.
Where is the pin you are speaking of in the bevel gear and how did you get to it.?
The leg is straight.

Bill
