This has been a big week for disassembly of the Worthington pumps! After long-term treatment in electrolytic reduction and removal of chlorides from the outer surfaces of the pumps, it’s time to remove as many of the internal moving parts as possible to make sure all surfaces are conserved. This week Eric and Gary removed the port pump damping piston from its steam chest, and also separated both port and starboard pump damping pistons from their valve rods.

This was accomplished by supporting the parts in a vertical hydraulic press and carefully applying pressure to the target areas with the help of tools and support plates made by Gary.

The valve rods, which were originally made with a precision machined tapered fit into the pistons, were successfully removed without damage, allowing for thorough treatment of all surfaces.

Stay tuned for Part 2!
