Hardinge Machine Tool Hydraulic Pipe Layout & Installation Kit BL1000013302A

Provide your machine's serial number to an authorized Hardinge distributor. They can reference the factory bill of materials to confirm that kit BL1000013302A is the complete set for a full hydraulic line replacement on your specific model. Some kits may be for a sub-section (e.g., only the turret circuit), so verification is key. The distributor should be able to provide a detailed packing list of the kit's contents for your review before purchase.

While physically possible, it is strongly discouraged. Generic components may not match the exact metallurgy, corrosion resistance, or pressure rating. The fitting thread forms (e.g., metric BSPP, JIC) or sealing methods (e.g., bite-type vs. O-ring face seal) must be identical to the original. Mismatches cause leaks. The OEM kit guarantees every component is correct, saving significant troubleshooting time and preventing potential system contamination or failure from an incorrect part.

Proper installation requires a quality tube bender for the specific tube diameter to avoid flattening or kinking. A sharp, deburring tube cutter is essential for clean cuts. For compression or flare fittings, the correct flaring or swaging tool must be used. A set of calibrated torque wrenches is necessary to tighten fittings to specification without damaging seals or threads. Having these tools ready before starting the job is crucial for a professional result.

Always use a calibrated tube bender designed for the tube's outside diameter. Measure and mark the bend points accurately from the old tube or a diagram. Make bends gradually, using the bender's form to achieve a smooth radius. The bend radius should never be tighter than the tubing manufacturer's (and OEM's) specification. A kinked or severely flattened tube will restrict flow, cause turbulence, and create a stress point likely to fail under vibration and pressure cycling.

Use a sharp, rotary tube cutter for a square cut. After cutting, use a deburring tool to remove all internal and external sharp edges or burrs. These burrs can cut O-rings, shred seals, and break off to become destructive contamination in the hydraulic system. The tube end must be perfectly clean and smooth. For flare fittings, the flaring process must be done precisely according to the fitting manufacturer's instructions to create a perfect sealing surface.
