Overview – Work Equipments SEAT;SPRING 163601 Series
The Hitachi SEAT;SPRING 163601 fits Hitachi work-equipment and linkage as the spring seat; because multiple part numbers interchange, we list the related series so you can match what is on your machine.
Parts Characteristics
A spring seat that locates and squares a spring against its mating component in the linkage or cylinder. It sets the spring’s axis and reaction face, so a true, undamaged seat keeps the spring loading the part it was designed to load.
Applicable Models & Applications
Fitted to Hitachi linkage positions of this shape. Match the seat profile and standoff against your old part – spring seats that look alike differ in how the spring seats and how far they sit off the face.
Maintenance & Replacement
Inspect seats for cracking and witness marks that no longer line up. A seat that has begun to move lets the spring cock, and a cocked spring loads the bore unevenly.
Re-torque the seat retention to specification, especially after linkage work. A seat that has loosened hammers its own bolts loose and cracks the casting it bolts to.
Fit the new seat true and square. A seat a few millimetres out throws the spring off-axis, and the resulting side load shortens both the seat and the component it carries.
Keep the seats for your model on the shelf. They are structural, not trim, and a failed one turns an inexpensive plate into a larger repair.
