Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Caterpillar Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Caterpillar products. Dispose of all fluids according to local regulations and mandates. |

- Inspect suction screen (3) and magnetic filter (4) for large particles of debris. An excessive amount of debris may be an indication of possible failure. Discolored oil or oil with an odor requires a careful analysis of SOS results. If large particles are found, consult your Caterpillar dealer for further analysis and additional guidance.
Note: Additional oil may drain from the oil pan when the cover is removed. Ensure that a suitable container is in place in order to capture any oil that may drain from the torque converter housing.
- Wash the suction screen and the magnetic filter in clean, nonflammable solvent. Clean the magnets with a cloth or a stiff bristle brush.
| NOTICE |

Do not drop or rap the magnets against any hard objects. The magnets are very brittle. Replace broken magnets or damaged screens. |
- Install the magnetic filter, the screen and the access plate. Tighten the access plate to 28 ± 7 N·m (21 ± 5 lb ft).
- Fill the transmission to the full mark on the dip stick at filler tube (5) with the recommended oil viscosity and volumes. Refer to Operation and Maintenance Manual, "Capacities (Refill)" for the appropriate oil volumes.
