Identify

How to identify a hydraulic hose before replacement

Record the hose, machine position, markings, length, fittings, and orientation before the old assembly leaves the machine.

Record these before removing the old hose

Machine: equipment type, brand, exact model, and serial range when available.
Position: system, component-to-component route, OEM figure, and callout or pipe number.
Length: value, unit, and the exact points used for the measurement.
Hose: every readable layline marking, inside diameter or dash size, construction, and pressure rating.
Both ends: male or female, swivel or fixed, thread diameter and pitch, seal face, angle, and shape.
Orientation: clocking between bent fittings, hose route, clamps, sleeves, and guards.
Photos: one wide route photo, one photo at each port, and one photo of all readable markings.

Find the machine record
Search by machine and model, then open the correct system. Match the installation diagram before relying on a part number.
Tag both ends
Mark the machine-side port and component-side port. This prevents two similar hoses from being swapped.
Copy the layline
Write down the complete printed line. Do not treat a construction name such as 1SN as a complete compatibility decision.
Measure and photograph
Record the measurement method and fitting clocking. A number without reference points is easy to misread later.
Match the whole assembly
Confirm pressure, temperature, media, hose family, compatible fittings, and approved crimp data as one system.
