Using my home made tool to remove solenoids. I drilled the nut and use two drill bits for removal.
Solenoid Block with Coils Removed
Solenoid Seat with #19 O-ring
Solenoid with Plunger
Solenoid with plunger removed
Block with part number
Plunger Dimensions. I think the red plunger tip gets dirty and leaks. It would be nice to find those tips. I cleaned the plungers.
Back together with new air fittings.
