Uniform bore count, inner hole size and external mounting outline; no secondary grinding required during hydraulic pump disassembly and repair.
Fine internal honing minimizes friction between barrel and pistons, lowering internal leakage and greatly extending overall pump service lifespan.
Genuine OEM, aftermarket equivalent and remanufactured versions are stocked to fit varied budget demands of wholesalers and mining enterprises.
Hardened alloy material withstands continuous high hydraulic pressure, resisting scratch and deformation under long-shift heavy mining operation.
FAQ
A：Obvious power attenuation, severe internal pump leakage, abnormal metal scraping noise and overheating; scratched or deformed inner bores cannot be restored by simple polishing.
Q: What specifications should be followed when installing 188-4164 barrel on Cat 336D?
A: Completely clear metal chips inside pump housing before assembly; lubricate each bore evenly with dedicated hydraulic oil; align spline position accurately to avoid stuck piston movement.
Q: What quality options are available?
A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
