Posted by SelkirkTMO on Sun Sep 2 23:23:11 2007, in response to Re: Brake Valve pr0n Re: LIRR MP-54 #1149 and its ME-23 brake valve, posted by randyo on Sun Sep 2 23:04:47 2007. First time I operated 1689 at Branford, the absence of the familiar detents was the very first thing I noticed. Had that happen to me now and then in meatball land so I knew about that disk and the spring pin having a tendency to eventually eat through that machined disk so that there was a rut down there instead of the detent holes. Both ends of 1689 seemed to have that problem, plus the rotor being a few degrees off from where it should have been which caused me to bring the handle parallel to the rails on the first try but no puffy of air. Had to move it almost over to the dump position to get an application.But that ME-23 arrangement showed up on a lot of commuter cars, but apparently the subway orders were customized a bit. When you raised the issue of the missing contact, went and consulted my copy of pamphlet T-5051-13 ("AMUE Brake Equipment for New York City Eighth Avenue Subway") published by Westinghouse Traction Brake Company (October, 1932) and then pulled out an hour and change length video that Heypaul made for me of ALL the internals of everything opened up and photographed to almost microscopic detail of every nut, bolt, contact and lockwasher. He even opened up the electric brake plug socket so that I could see the wiring inside the bakelite contact assembly there as well as tracking out EVERY pipe. :) Apparently there were quite a few variations on that stand, based upon who wanted one.
