My dear friends, after successive episodes of the difficulty solving the problem of frozen shaft, with injection of WD-40, 2-stroke
oil,
diesel, rust remover, the best solution was with the use of a torch at the base shaft.
Problem:
Salt and maybe rust.
Solution: Orings still in good condition, after
heating, grease and more grease where pushed all the
salt out.
At this time the shaft is more like butter. Just one finger to turn the
wheel.
My thanks to everyone who helped me, thank you very much.
