Rejuvenating Silca track pump
My 40-year-old Silca track pump has been getting a bit dodgy - the leather washer was rather worn and leaking, ditto for the check valve, and as I don't put more than 60psi in any tyres these days, I was only ever operating in the bottom 25% of the 0-240psi gauge on the pump, with consequent inaccuracy of the readings. I unscrewed the old gauge, which required a fair bit of force as the threads were corroded, and found that it used a 1/8 NPT thread, so I ordered a compatible 50mm diameter Wika gauge with 0-600kPa range and a claimed 2.5% accuracy. The Wika dial has a secondary scale in psi (0-87psi) - I believe in the US you can order the same gauge with psi as the primary scale.
I also ordered a new check valve and washer, and the pump is now back in full working order, and considerably more useful for my purposes with the new gauge.
I probably could have bought a brand new floor pump for not much more than I spent on the replacement parts, but I prefer repairing what I have rather than replacing it with something else.
