Product Description
Premium 153510SK Hydraulic Breaker Service Repair Kit for Komatsu KB155
Maintain the hard-hitting efficiency and operational uptime of your Komatsu KB155 hydraulic rock hammer with the 153510SK professional service repair kit. Engineered for 15 to 22-ton class excavators, the KB155 requires superior sealing integrity to withstand continuous high-pressure cycles during tough rock excavation, concrete demolition, and trenching jobs.
At Toparts, we manufacture our Komatsu-compatible kits using advanced Polyurethane (PU) and NBR formulations. These industrial-grade materials ensure a precision fit, preventing critical oil blow-by and protecting your heavy equipment investment from premature wear.
Product Highlights:
100% Precision Match: Specifically engineered to replace Komatsu Part Number 153510SK, guaranteeing a seamless, zero-gap installation on KB155 hammers.
Industrial-Grade Durability: Forged from premium PU with high tensile strength and tear resistance to handle the high-frequency vibrations of Komatsu demolition attachments.
Restore Impact Energy: Effectively seals both gas and oil chambers, preventing nitrogen leakage and fluid bypass to restore your hammer's original factory hitting power.
Excellent Thermal Stability: Formulated to resist hardening and extrusion, maintaining optimal elasticity even during continuous operation in hot climates or deep quarries.
Complete Overhaul Set: Includes all critical rod seals, buffer seals, dust wipers, and specialized O-rings required for a professional-level cylinder rebuild.
