Inspection of guards
1. Switch off and isolate Generator set.

2. Locate fan guard as per image 1.1.1.

Image1.1.1

3. Area of inspection is to be around the bend of the guard and along the entire circumference of the circular guard assembly, on the last 5 Rods, as per image 1.2.1.

Image1.2.1

4. Inspect weld quality using the following examples of criteria required in images 1.3.1, 1.3.2, 1.3.3, 1.3.4, 1.3.5 and 1.3.6.

Image1.3.1

Image1.3.2

Image1.3.3

Image1.3.4

Image1.3.5

Image1.3.6

5. If a poor weld is found in a quadrant or there is any doubt, that quadrant should be removed and replaced with a new guard. For obtaining a replacement guard, have the Dealer Technical Communicator (TC) submit a request for the parts to CPI number 401233 through CPI Feedback within the Service Information Management System (SIMSi).

6. Guard should be lined up with fixing holes in shroud, while loosely fixing bolts into position. Fixing bolts should only be torqued up to 55Nm +/- 10 when all bolts have been lined up with fixing holes. No bolts should be forced into position during this assembly, as this would pre-stress the guard.

7. Each claim story must include 2 photographs. The first showing a close up of the failure and the second showing the position of the failure on the guard assembly i.e. where on the 1 o' clock to 12 o' clock position. Use image 1.4.1 to aid describing all failure locations.
