Hydraulic Piston Pump Remanufacturing
|
|
|
Every piston pump is assembled from cylinder blocks, valve plates, and piston shoe subassemblies that have been checked and/or remanufactured to exact tolerance
|
|
|
Every cylinder block has each bore diameter checked including its concentricity to ensure pump efficiency
|
|
|
Every cylinder block face is machine lap polished to 12 millionths of flatness and is surface treated to allow a thin layer of oil to exist between mated parts |
|
|
Every valve plate is machine lap polished to 12 millionths of flatness
|
|
|
Every metering and timing notch on the plate is checked and any found out of tolerance are cut to meet specifications
|
|
|
The plate is surface treated to ensure no internal slippage |
|
|
Every piston shoe subassembly diameter is matched with cylinder bore diameters to ensure efficiency within manufacturer's tolerances
|
|
|
Piston shoe height is checked on each shoe using a micrometer to ensure the component is within tolerance
|
|
|
Each pump is further tested to manufacturer's specification before it is released
