PROBLEM
The stator leads needs to be inspected on certain C27 Engine Generator Sets equipped with 1200 Frame (SR5)generators.

This failure, in conjunction with other factors, may result in a risk of personal injury or death.

ACTION REQUIRED
Inspection Procedure
1. Isolate the engine generator set before commencing any work on the unit. Lock open the generator breaker, activate the Emergency Stop, disconnect the battery cables, and either disconnect or open the control circuit breaker for the AC power supply to the battery charger. Ensure all health and safety requirements are adhered to at all times. Also, ensure proper Lock Out-Tag Out procedures are followed at all times while work is being performed on the unit. Lock out engine generator set operation and disconnect and lockout all power sources before commencing any work.
2. Locate and remove cover shown on Image 1.
3. Measure the clearance between the stator leads and the sharp edge of the generator control cabinet, i.e. check all direction. The clearance should be at least 3/4" (19mm). For reference see Image 2.
4. Measure the clearance between the stator leads and the threaded inserts (rivet nuts) inside the panel. The clearance should be at least 3/8" (10mm). Please note:
