Abstract :
The undercarriage is the lower part of a crawler tracktor that functions to support the load, direct, and support the unit. Undercarriage has a very important role in excavators where all excavator operations require an undercarriage as a unit stabilizer. Another function of the undercarriage is to support and transmit the load of the excavator unit to the ground, as an excavator propulsion component and to support the unit. The damage that occurs to the Undercarriage on the XCMG XG822EL Excavator unit is the Track adjuster component where the piston rod cylinder is rusted and the seal is brittle resulting in fluid leakage. This is known when an inspection is carried out after the disassembly of the Track adjuster is carried out. Damage that occurs to the piston rod cylinder and seal interferes with the work of the Track adjuster due to lack of lubrication.
Repairs made to the piston rod cylinder were to clean the rust using sandpaper until it was clean again, while the brittle track adjuster seal could not be repaired so it had to be replaced with a new seal kit.
