Here you have a couple of Rexroth A11VO pump parts, damaged by
extremely high temperature. It is not uncommon for heavy machinery to
catch fire, and so every once in a while fire-damaged hydraulics
appears in every workshop. In this particular case, the multi-ton
forklift had been topped up with fuel moments before the fire started...
To get an idea of how high the temperatures
around the hydraulic pump (the machine had two of these) went, have a
look at the high pressure hydraulic hose that was mounted at the pump's outlet. The steel wire mesh melted down!!!
There you have it - once again through simple observation IH
has discovered another uncommon and unique disassembly technique! If
you want to re-sleeve your barrel, and don't know how to dismount the
old brass sleeves - set your pump on fire - the sleeves will come out
by themselves and all this (!) without opening the pump!!!
