Q: Why is my PC200-7 excavator losing hydraulic power when hot?
A: This is often caused by internal leakage within the 702-21-07142 cylinder block. As the oil thins with heat, worn surfaces allow pressure to bypass, reducing work speed. Replacing with a precision-ground block restores power.
Q: How to identify if the 702-21-07142 needs replacement during an overhaul?
A: During inspection, check for scratches, pitting, or discoloration on the cylinder face. If the surface isn't perfectly flat, it will fail to hold pressure. Our OEM-standard replacement ensures a perfect seal.
Q: Why Choose This Cylinder Block?
A: It features an OEM-standard tri-metal structure and is trusted by repair shops & equipment fleets globally for its durability in extreme conditions.
