OEM 318502144 The XCMG Spring Plate 318502144 is a genuine spring-steel retaining plate that keeps a pin, lever or cover seated on XCMG hydraulic excavators.
Issued under the official part number 318502144, the plate gives the technician a correctly sized retainer that matches the groove, bolt spacing and spring pressure it is designed for.
The plate is stamped and heat treated to the XCMG drawing, so the outline, hole pattern and curved lip fit the housing without filing or reaming.
Spring pressure holds the plate against the retained part, so it does not rattle loose or walk out of position under vibration.
A protective plating resists water, dust and corrosion, so the plate keeps its spring load and finish through wash-down and long outdoor duty.
Every piece is checked for hole spacing, thickness, spring height and flatness before the batch is packed for shipment.
Fitted to linkage pins, handle pivots and panel covers, this spring plate keeps small joints locked, aligned and easy to service.
The 318502144 plate is produced to the XCMG drawing, so the holes and curved lip line up with the housing on the first attempt.
Spring pressure holds the retained part against the seat, so the pin or lever does not rattle loose under vibration.
Correct thickness and heat treatment keep the plate springy, so it presses firmly without flattening out after a few uses.
The plated finish resists water, dust and wash chemicals, so the plate does not rust, pit or seize against the housing.
Because the part matches the OEM number, a fitter installs it straight from the bag without bending, filing or adding shims.
Even hole spacing spreads the bolt load, so the plate sits flat and does not cock sideways when tightened down.
A sound plate also stops pins from scoring the bore, which protects the housing and extends the life of the joint.
Keeping a spare plate on the shelf shortens repair time, so a flattened retainer does not leave a joint loose.
Each lot begins with certified spring steel sheet tested for thickness, hardness and tensile strength before it reaches the stamping line.
Plates are stamped and bent in controlled tooling, so the outline, hole pattern and lip form stay uniform from batch to batch.
Deburring removes sharp edges from the holes and lip, so the plate seats flat and does not cut hands or the housing face.
Inspectors measure hole spacing, thickness, spring height and flatness against a gauge made for this exact part number.
Batch records trace every 318502144 plate to its steel lot and production run, so a quality question is settled quickly.
A spring plate presses on a pin, lever or cover, so the retained part stays seated against its stop while the machine works.
A flattened or broken plate lets the retained part move, which causes rattle, wear and can allow the part to drop out.
The genuine 318502144 keeps the joint loaded, so the retained part stays in place and the housing stays protected.
Correct fit avoids both a plate that works loose under vibration and one that presses too hard and binds the mechanism.
A sound plate protects pins, levers and covers, which keeps service intervals predictable and extends machine life.
The 318502144 plate is installed with a cleaning cloth, a spanner set and pliers during linkage or panel service work.
Remove the old plate, clean the housing and check the bore so no dirt or metal chips sit under the new part.
Check the groove, holes and housing face for burrs, rust or cracks, since a rough surface will stop the plate seating flat.
Seat the retained part, fit the plate with the lip in the groove and start the bolts by hand to avoid cross-threading.
Tighten to the torque in the service data, so the plate loads the part without flattening the spring or stripping the thread.
Move the retained part slowly, then check that it stays seated and that the plate does not move or rattle.
At service intervals, look for a loose plate, a flattened lip or a rusty face and renew the part before the joint fails.
Every 318502144 plate is produced in an ISO 9001 and ISO 14001 certified plant with traceability from steel to carton.
Incoming steel is tested for thickness and hardness, and finished plates are gauged for hole spacing, thickness and spring height.
Each batch is screened for cracks, burrs and coating defects, since these flaws let the plate lose its spring or snap under load.
Post-production checks include visual review, dimensional verification and a trial fit in the XCMG housing fixture.
Sample plates from each batch undergo load, fatigue and salt spray tests to confirm spring performance and corrosion resistance.
Cheap copies often use thin sheet without proper heat treatment, so the plate flattens or cracks soon after installation.
A plate with the wrong hole spacing or lip height can sit proud, bind the mechanism or fail to hold the retained part.
The genuine 318502144 is made to the XCMG drawing, so outline, holes, lip and material match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps fit with OEM housings.
Backed by XCMG global quality standards and technical support, this spring plate performs reliably in harsh conditions.
Choosing the genuine 318502144 plate prevents a small loss of tension from turning into a scored bore or a loose joint.
A failed plate lets the retained part move, which wears the housing and can damage the seal and linkage around it.
A correctly made plate holds firmly, so it does not need repeated tightening and does not wear out the housing face.
Reliable plates 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 318502144 plate with efficient stamping runs that keep production scrap low.
A long service life means fewer replacements, which lowers the material and energy tied to each plate.
Keeping joints loaded 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 318502144 plate 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 plate flat and the lip undamaged until fitting, avoiding the distortion seen in loose storage.
