ADAPTER (LH) 5332638 - Caterpillar

Refer to Table 3. Perform the following action if the values from the wear element analysis of your oil sample equal the values in the table. Make sure that the oil is drained and that the final drive compartment is flushed at the earliest convenience. The sample should be given a Yellow Alert status. Evaluate another oil sample after 125 service hours. Continue operation if the oil sample that was obtained at 125 service hours is normal. Continue with a normal sampling interval and a normal oil drain interval.

Refer to Table 4. Perform the following action if the values from the wear element analysis of your oil sample equal the values in the table. Drain the oil from the final drive compartment. Schedule service for the final drive within the next 50 hours. Flush the final drive compartment in order to remove the contamination and the wear metals. The sample should be given a Yellow Alert status. Evaluate another oil sample after 125 service hours. Continue operation with a normal sampling interval and a normal oil drain interval, if the oil sample from the 125 service hour interval is normal.

Refer to Table 5. Perform the following action if the values from the wear element analysis of your oil sample equal the values in the table. The oil should be drained immediately from the final drive compartment. Flush the final drive compartment in order to remove contamination and wear metals. The sample should be given a Red Alert status. Evaluate another oil sample within 50 service hours. If the final drive continues to produce levels of Cr that exceed 12 ppm, inspect the final drive for abnormal gear and bearing wear. Make the necessary repairs.

Refer to Table 6. Perform the following action if the values from the wear element analysis of your oil sample equal the values in the table. This applies to either the Fe value or the Cr value. Make sure that the final drive is immediately inspected. The sample should be given a Red Alert status. Relatively low levels of Si indicate that the entry of dirt is not causing the abnormal wear. A component failure could be occurring.
