Tuesday, February 23. 2010GE Quality Builds Jobs, Burlington Northern 5383 5383 electrical cabinet "GE Quality Builds Jobs" is what was printed on a placard right above the work area on Burlington Northern 5383 this past Sunday, as the reverser was removed to be repaired. Early last year, the reverser failed during a load box test that we normally do after the locomotives inspection. The steel of the top rear of the electrical cabinet had deteriorated, with a change in rpm during the load box test, the intermittent vibration throughout the locomotive caused a large enough piece of rust to drop from the top of the cabinet into the reverser while it was under load.  5383 reverser The loco was making about 1,800HP at the time based on the calculation done from the meter plugged into the multiplier card. The rust just happened to fall into the reverser on the center two lugs which are the main positive and negative feeds from the diode banks of the alternator. All the diodes were tested and all are in good shape. The damage was on the back side of the reverser as it was mounted and it was quickly determined that a repair wasn't going to be easy and not going to be done in place.  Tagged and disconnected cables and bus bars On the 15th, Dan C came out to tag and label all of the cables and start unbolting all the connections and bus bars. On the 21st, Wes L and Jim W removed it from the 5383 and placed it on a bench in the shop. Some pictures have been uploaded to a photo gallery. The next steps are to start hunting down parts to replace the burned up insulators in the reverser. At the same time we'll need to take the torch to the fresh paint and start replacing the supports and top of the back half of the electrical cabinet. The estimated cost of the repairs at this point is about $1,500. |

I was not around at the time. General discussion suggests that it was "pretty marginal" in a number of areas. Nigel

No, it will not be necessary to hold any of the work waiting for the plow to be turned, end for end. Weather will be the major factor, but there will [...]

Ah yes, I have made such Jibs myself. If it were me, I would add in each corner an angled piece from the base to the Jib to act as sway bracing. [...]
