I need to dismantle an LBSC style lubricator - this is the ratchet and pawl type sold by Blackgates and other model engineering supplies.
In order to get the pump assembly out of the tank, it would appear I need to remove either the ratchet wheel or the crank wheel which operates the pump piston, but which? And do they unscrew or are they force fit?
Any assistance would be appreciated.
