Problem:
Several changes are needed for the nitrogen and oil charging procedures that are used on the front and the rear suspension cylinders.
Solution:
The following updates have been made to the specified core documents to reflect the changes in the nitrogen and oil charging procedures:
The Charging Tools section of RENR2615; Testing and Adjusting/797 Off-Highway Truck Suspension Cylinder/Testing and Adjusting Section contains the following changes:
Table 3 should be changed to include the following information:
The Suspension Cylinder (Front) - Purge and Charge section of RENR2615; Testing and Adjusting/797 Off-Highway Truck Suspension Cylinder/Testing and Adjusting Section contains the following changes:
Setting Up For Measurement
The dimension for the nitrogen charging procedure should be changed to the following:
- 265.0 mm (10.43 in) + 58.2 mm (2.25 in) = 323.2 mm (12.68 in)
Nitrogen Charging Procedure
The regulated pressure that is referenced in Step 7 should be changed to 2791 kPa (405.1 psi).
The Suspension Cylinder (Rear) - Purge and Charge section of RENR2615; Testing and Adjusting/797 Off-Highway Truck Suspension Cylinder/Testing and Adjusting Section contains the following change:
Setting Up For Measurement
Table 5 should be changed to the following:
In Step 5, the corrected guidelines for the nitrogen charging procedure should be changed to the following:
- 120.7 mm (4.75 in) + 23 mm (0.9 in) = 143 mm (5.61 in)
- 133.4 mm (5.25 in) + 23 mm (0.9 in) = 155 mm (6.11 in)
The Worksheets section of RENR2615; Testing and Adjusting/797 Off-Highway Truck Suspension Cylinder/Testing and Adjusting Section contains the following change:
