SHAFT PISTON GASKET REPLACEMENT
The u-cup shaft piston gasket, over time can lose its efficiency and cause some small leaking, especially in the initial phase of heating
I used, to solve the inconvenience, a rubber washer in silicone, but to avoid damaging it while inserting the shaft piston, I propose a different way of replacement.
disassemble the shaft from the piston
put the new gasket
put the ring nut
put a little bit of lube and insert the shaft
screw the ring nut
put the spring
put the piston body
screw the piston body
