PARTS DISPOSITION

Handle the parts in accordance with your Warranty Bulletin on warranty parts handling.

Rework Procedure

1. Refer to Disassembly and Assembly KENR6052 - "Engine Oil Pan-Remove" for specific instructions to remove the front section of the oil pan.

2. Starting with bolt 1 (Image 1.2.1), remove the existing bolt. Ensure that the threads in the block are clean and free of oil or debris prior to installing the new fastener. Ensure any previously applied Loctite is removed from the threads.

Image1.2.1

3. Apply Loctite 243 along thread engagement length (20mm from bolt end), as shown in Image 1.3.1. Torque fastener to 40 N-m and then turn an additional 60 degrees. Torque process should be completed within 10 minutes of applying Loctite. Temperature above 15 C. Care must be taken to prevent the Loctite from contacting the bolt underhead, as this can cause increased assembly friction resulting in reduced clamp load of the fastener.

Image1.3.1

4. Repeat step 2 and 3 for bolt 2 (Image 1.2.1).

5. Starting with bolt 3 (Image 1.2.1), remove the existing bolt. Ensure that the threads in the block are clean and free of oil or debris prior to installing the new fastener. Ensure any previously applied Loctite is removed from the threads.

6. Apply Loctite 243 along thread engagement length (20mm from bolt end), as shown in Image 1.3.1. Torque fastener to 40 N-m and then turn an additional 90 degrees. Torque process should be completed within 10 minutes of applying Loctite. Temperature above 15 C. Care must be taken to prevent the Loctite from contacting the bolt underhead, as this can cause increased assembly friction resulting in reduced clamp load of the fastener.

7. Repeat step 5 and 6 for bolt 4 (Image 1.2.1).

8. Following completion of the scavenge pump bolt replacement, refer to Disassembly and Assembly KENR6052 - "Engine Oil Pan - Install - C175-20"
