What are the possible causes of elevated oil temperature in the loader's transmission oil pan due to a large amount of aluminum shavings or metal shavings?

(1) A large amount of aluminum shavings in the oil pan indicates mutual wear between the torque converter's working wheels, resulting in reduced transmission efficiency and overheating of the working oil.
(2) A large amount of copper shavings in the oil pan indicates friction or slippage between the driving and driven friction plates. The transmission oil level and shift pressure should be checked. If normal, the problem is likely due to improper assembly or deformation of the driving and driven friction plates.

(3) Iron shavings in the oil pan indicate slippage of the overrunning clutch. When the loader transitions from high speed with light load to low speed with heavy load, there is a metallic friction sound in the transmission, and the machine lacks power.
(4) Bearing fragments in the oil pan generally indicate bearing damage in the dual-transmission assembly. The situation should be assessed, and the damaged parts should be disassembled, inspected, and replaced. If the above phenomena are found, a judgment should be made based on the specific situation. The torque converter or gearbox should be disassembled and the damaged parts replaced. Do not continue to use it.
