Make sure your unloading auger is in the manual position, sometimes the limit switch will not work when the auger is folded back in the auto position and the pump will stay under a load all the time and burn up.

by 'blowing up' do you mean as in a terrorist action, or did the shaft twist IJ Actually 3400 hours on those pumps is about the life of them unless super clean oil was kept in as in changed ofter, no pressure_heat issues as Kevin mentions, and filters were replenished over regularly. There is a flow divider in the end of the pump for the power steering - a flake of aluminium can either stick it and cause a pressure spike as the ps relief can really seat itself after this many hours, or the flake can wedge in the gears and cause a lock up. I would not be afraid of a used pump if it was at a low price. 71348232 pumps are not cheap - maybe someone has an alternate sourceIJ If the first case mentioned happened - write the Speaker of the House until the Pres gets back.
