I support all the recommendations to disassemble it first. By the way, when I disassembled it, this simple pump taught an history lesson. It is a British made Whale Gusher, a very good pump. My only problem was the nut, totally eaten out by corrosion. Simple, I'll find another nut. Well, the nut I purchased didn't fit. Might be a metric one. Nope. Doing some research, I found out that the nut coming from England was made using the Whitworth standard, not available in North America. I contacted the importer who wanted to sell me a kit for 70$. Are you nut? I won't purchase a 70$ kit to replace a simple nut. Ok, let's go on wiki, to find out that the Whitworth was the very first standard for nuts and bolt. "The Whitworth thread was the world's first national screw thread standard,[1] devised and specified by Joseph Whitworth in 1841. Until then, the only standardization was what little had been done by individual people and companies, with some companies' in-house standards spreading a bit within their industries. Whitworth's new standard specified a 55° thread angle and a thread depth of 0.640327p and a radius of 0.137329p, where p is the pitch. The thread pitch increases with diameter in steps specified on a chart. The Whitworth thread system was later to be adopted as a British Standard to become British Standard Whitworth. An example of the use of the Whitworth thread is the Royal Navy's Crimean War gunboats. These are the first instance of "mass-production" techniques being applied to marine engineering as the following quotation from the obituary from The Times of 24 January 1887 to Sir Joseph Whitworth (1803–1887) shows: The Crimean War began, and Sir Charles Napier demanded of the Admiralty 120 gunboats, each with engines of 60 horsepower, for the campaign of 1855 in the Baltic. There were just ninety days in which to meet this requisition, and, short as the time was, the building of the gunboats presented no difficulty. It was otherwise however with the engines, and the Admiralty were in despair. Suddenly, by a flash of the mechanical genius which was inherent in him, the late Mr John Penn solved the difficulty, and solved it quite easily. He had a pair of engines on hand of the exact size. He took them to pieces and he distributed the parts among the best machine shops in the country, telling each to make ninety sets exactly in all respects to the sample. The orders were executed with unfailing regularity, and he actually completed ninety sets of engines of 60 horsepower in ninety days – a feat which made the great Continental Powers stare with wonder, and which was possible only because the Whitworth standards of measurement and of accuracy and finish were by that time thoroughly recognised and established throughout the country.
An original example of the gunboat type engine was raised from the wreck of the SS Xantho by the Western Australian Museum. On disassembly, all its threads were shown to be of the Whitworth type.[2]" How did it ended up? I was traveling to England for vacation that summer. I found a shop in Portsmouth and had a great conversation with the shop owner who sold me a pair of half inch whitworth treaded nuts. I keep the second one preciously in my garage.
