My dear friends, after successive episodes of the difficulty solving the problem of frozen shaft, with injection of WD-40, 2-stroke oil
, rust remover, the best solution was with the use of a torch at the base shaft.
and maybe rust.
Solution: Orings still in good condition, after heating
, grease and more grease where pushed all the salt
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.
