OEM 318814005 The XCMG Pin 318814005 is a genuine pivot pin that carries a joint through its rotation on XCMG hydraulic excavators.
Issued under the official part number 318814005, the pin gives the technician a correctly sized part that matches the bore, boss width and retaining groove it is designed for.
The pin is turned and ground to the XCMG drawing, so the diameter, length and chamfer slide into the bores without force or reaming.
A smooth ground surface lets the pin rotate freely in the bushings, so the joint moves without scoring or seizing under load.
A protective plating resists water, dust and corrosion, so the pin keeps its diameter and finish through wash-down and long outdoor duty.
Every pin is checked for diameter, length, chamfer and groove position before the batch is packed for shipment.
Fitted to boom pivots, linkage joints, bucket bosses and cylinder eyes, this pin keeps connected parts rotating on a true axis.
The 318814005 pin is produced to the XCMG drawing, so the diameter and length slide into the bores on the first attempt.
A ground surface lets the pin rotate freely in the bushings, so the joint moves smoothly without scoring or seizing.
Correct chamfer guides the pin past the bore edge, so the bushing is not cut or pushed out during installation.
The plated finish resists water, dust and wash chemicals, so the pin does not rust or seize in the joint over time.
Because the part matches the OEM number, a fitter installs it straight from the bag without machining or adding shims.
Correct hardness keeps the pin straight under load, so it does not bend or wear into an oval inside the boss.
A sound pin also keeps the joint aligned, which protects bushings, seals and the surrounding structure from wear.
Keeping a spare pin on the shelf shortens repair time, so a worn pivot does not turn into a full day of lost work.
Each lot begins with certified steel bar tested for chemistry, hardness and tensile strength before it reaches the machining line.
Pins are turned and ground on CNC equipment, so the diameter, length and groove stay uniform from batch to batch.
Deburring and chamfering smooth the pin ends and groove edges, so the part slides in cleanly and does not cut the bushing.
Inspectors measure diameter, length, chamfer, groove position and finish against a gauge made for this exact part number.
Batch records trace every 318814005 pin to its steel lot and production run, so a quality question is settled quickly.
A pin joins two or more parts so they can rotate around a common axis without separating under load.
A worn or bent pin lets the joint go slack, which hammers the bushings, wears the bosses and causes unexpected failure.
The genuine 318814005 keeps the joint tight, so connected parts stay aligned and the bushings stay protected.
Correct fit avoids both a pin that rattles in an oversize bore and one that seizes from being pressed in too tight.
A sound pin protects bushings, seals and structure, which keeps service intervals predictable and extends machine life.
The 318814005 pin is installed with a cleaning cloth, a punch and a spanner set during linkage or hydraulic service work.
Support the linkage, release the load and clean the bores so no dirt or metal chips enter during the repair.
Check the bores and bushings for burrs, rust or oval wear, since a rough surface will stop the pin seating correctly.
Apply clean grease, drive the pin in straight and confirm it passes through all the bosses before fitting the retainer.
Fit the snap ring, bolt or plate to the service data, so the pin cannot walk out under vibration.
Cycle the joint slowly, grease the pin and check that the linkage moves freely after the first working cycles.
At service intervals, look for a loose pin, a missing retainer or oval wear and renew the part before the joint opens.
Every 318814005 pin is produced in an ISO 9001 and ISO 14001 certified plant with traceability from steel bar to carton.
Incoming steel is tested for chemistry and hardness, and finished pins are gauged for diameter, length and groove position.
Each batch is screened for cracks, laps and coating defects, since these flaws cause the pin to bend or break under load.
Post-production checks include visual review, dimensional verification and a trial fit in the XCMG boss fixture.
Sample pins from each batch undergo load, fatigue and salt spray tests to confirm strength and corrosion performance.
Cheap copies often use soft steel or rough turning, so the pin wears oval, scores the bushing and starts to rattle.
A pin with the wrong diameter or groove can seize in the bore, walk out of the joint or fail to take the retainer.
The genuine 318814005 is made to the XCMG drawing, so diameter, length, groove and material match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps fit with OEM bushings.
Backed by XCMG global quality standards and technical support, this pin performs reliably in harsh conditions.
Choosing the genuine 318814005 pin prevents a small amount of joint play from turning into a worn boss or bushing.
A failed pin lets the joint go slack, which hammers the structure and can separate the linkage under load.
A correctly made pin holds firmly, so it does not need repeated replacement and does not wear out the bushings.
Reliable pins also keep joints tight, which improves machine performance and lowers ownership cost.
Service records from construction and mining fleets show genuine XCMG parts cut unplanned downtime.
XCMG produces the 318814005 pin with efficient turning and grinding runs that keep production scrap low.
A long service life means fewer replacements, which lowers the material and energy tied to each pin.
Keeping joints tight prevents oil leaks and contamination, which protects soil, groundwater and internal parts.
The materials in this part comply with RoHS and REACH requirements for safe handling and responsible recycling.
The 318814005 pin is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each unit is bagged to protect the finish and boxed in a strong carton that guards against dust, damp and crushing.
Fleet buyers can request volume pricing and combined freight, which simplifies planning and lowers landed cost.
Live stock data and responsive supply teams cover urgent requests fast, so machines return to work sooner.
Careful packing keeps the pin straight and the ground surface undamaged until fitting, avoiding the damage seen in loose storage.
