The 707-99-72370 Boom Hydraulic Cylinder Seal Kit is designed for the boom hydraulic cylinder used on selected Komatsu construction equipment. This hydraulic cylinder seal kit is intended to restore reliable sealing performance within the boom cylinder, helping prevent hydraulic oil leakage and maintain the hydraulic pressure required for controlled boom raising and lowering. It is suited to demanding construction, earthmoving, mining, quarrying and heavy excavation applications where hydraulic cylinder reliability is essential to machine productivity.
The boom hydraulic cylinder supports the primary lifting and lowering movement of the excavator front attachment. It operates under substantial hydraulic pressure and repeated loading cycles, making its sealing components subject to progressive wear. Damaged or worn seals can contribute to external hydraulic oil leakage, reduced hydraulic efficiency, slow boom movement, boom drift and internal pressure bypass. Replacing worn sealing components with the correct seal kit can help restore cylinder performance, maintain hydraulic pressure and reduce unplanned machine downtime.
Typical Applications
Construction • Earthmoving • Mining • Quarrying • Heavy Excavation • Civil Infrastructure • Road Construction • Demolition • Material Handling
Common Symptoms
- Hydraulic oil leakage from the boom cylinder
- Boom drifting during operation
- Slow boom raising or lowering
- Reduced boom lifting performance
- Internal hydraulic pressure bypass
- Difficulty maintaining boom position
- Reduced hydraulic system efficiency
