TECHNICAL INFORMATION BULLETIN November 21, 2001
Generator Set PM3516 (BPD)
Component Code(s) 7060SUBJECT: XQ 2000 Power Module Slide Rail on 3500B Diesel Generator Sets
PROBLEM:
The 141-6413 Rail Group - Slide was used to facilitate the correct positioning and installation of the 3516B Generator Set into a Power Module. In some power modules, there was a possibility that the Generator Set base rail could come in contact with the slide rail which is installed on the container floor. This contact was possible due to "tolerance stack" on the components. This was a random occurrence that caused no detrimental effects to the switchgear or any other Power Module component. No failures were caused by this situation.
SOLUTION:
With the current assembly equipment in Caterpillar's Griffin Georgia facility, the need for the guide rails no longer exists. The Generator Set Assembly is pushed inside the Power Module container utilizing a hydraulic ram device. This hydraulic ram device correctly positions the Generator set without relying on the guide rails. The use of the 141-6413 Rail Group - Slide for the 3516B Generator Set installation has therefore been eliminated in 3516B Power Module product built after August 10, 2001.
