OEM 318502138 The XCMG Door Stop Mounting Bracket 318502138 is a genuine structural bracket that anchors the door stop block to the cab frame on XCMG hydraulic excavators.
Issued under the official part number 318502138, the bracket gives the technician a correctly sized mount that matches the frame holes, stop position and door swing arc it is designed for.
The bracket is cut, formed and welded to the XCMG drawing, so the base plate, arm and holes align with the cab frame without drilling or slotting.
A folded web and gusset stiffen the arm, so the bracket holds the stop steady instead of flexing when the door swings against it.
A protective coating resists water, dust and corrosion, so the bracket keeps its strength and finish through wash-down and long outdoor duty.
Every unit is checked for hole spacing, arm angle, weld quality and flatness before the batch is packed for shipment.
Fitted to cab doors, engine covers and access panels, this bracket holds the door stop in the exact position that protects the door and frame.
The 318502138 bracket is produced to the XCMG drawing, so the base plate and arm line up with the cab frame on the first attempt.
A stiffened arm holds the stop block at the correct angle, so the door meets the stop evenly instead of hitting one edge.
Welded gussets keep the bracket from flexing, so the door stop absorbs the impact instead of the frame or the hinge.
The coating resists water, dust and wash chemicals, so the bracket does not rust through or flake apart in outdoor service.
Because the part matches the OEM number, a fitter installs it straight from the box without drilling, bending or adding spacers.
Correct section thickness keeps the bracket rigid under impact, so it does not distort or crack at the mounting points.
A sound bracket also keeps the door stop firm, which protects the door edge, glass and frame from hard swings.
Keeping a spare bracket on the shelf shortens repair time, so a bent mount does not leave the door stop unsupported.
Each lot begins with certified steel plate tested for thickness, chemistry and tensile strength before it reaches the fabrication line.
Brackets are cut and welded in controlled fixtures, so the base plate, arm and holes stay square and uniform from batch to batch.
Grinding and deburring clean the weld edges and holes, so the bracket seats flat and does not cut hands, hoses or the door seal.
Inspectors measure hole spacing, arm angle, length, width and weld quality against a gauge made for this exact part number.
Batch records trace every 318502138 bracket to its steel lot and production run, so a quality question is settled quickly.
A door stop mounting bracket anchors the stop block so the door meets a firm limit at the correct open angle.
A bent or cracked bracket lets the stop move, which allows the door to swing too far and damage the hinge, glass or frame.
The genuine 318502138 keeps the stop fixed, so the door, frame and hinge stay aligned through thousands of open and close cycles.
Correct fit avoids both a bracket that rocks on a rough frame face and one that sits too far forward and blocks the door seal.
A sound bracket protects the door, stop and frame, which keeps the operator station safe and extends the life of the assembly.
The 318502138 bracket is installed with a cleaning cloth, a spanner set and a torque wrench during cab or body service work.
Support the door, remove the old bracket and clean the mounting face so no dirt or old thread locker sits under the new part.
Check the frame and door edge for cracks, rust or bent metal, since a damaged face will stop the bracket sitting flat.
Fit the bracket with the correct bolts, start the threads by hand and fit the stop block before tightening.
Tighten to the torque in the service data, so the bracket stays put without crushing the plate or stripping the thread.
Swing the door slowly to confirm the stop angle, then check that the seal and latch still meet correctly.
At service intervals, look for loose bolts, a bent arm or a cracked weld and renew the part before the door over-travels.
Every 318502138 bracket is produced in an ISO 9001 and ISO 14001 certified plant with traceability from steel to carton.
Incoming steel is tested for thickness and chemistry, and finished brackets are gauged for hole spacing, arm angle and dimensions.
Each batch is screened for weld porosity, cracks and coating defects, since these flaws let the bracket fail under impact load.
Post-production checks include visual review, dimensional verification and a trial fit on the XCMG cab frame fixture.
Sample brackets from each batch undergo load, vibration and salt spray tests to confirm strength and corrosion performance.
Cheap copies often use thin plate and light welds, so the bracket bends or cracks soon after the door starts hitting the stop.
A bracket with the wrong hole spacing or arm angle can sit crooked, shift the stop point or leave the door over-travelling.
The genuine 318502138 is made to the XCMG drawing, so outline, holes, arm angle and material match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps fit with OEM cab frames.
Backed by XCMG global quality standards and technical support, this bracket performs reliably in harsh conditions.
Choosing the genuine 318502138 bracket prevents a small bend from turning into a broken door stop or a damaged frame.
A failed bracket lets the stop shift, which allows the door to over-travel and crack the glass or tear the hinge.
A correctly made bracket holds firmly, so it does not need repeated tightening and does not wear out the frame holes.
Reliable brackets also keep the door stop working, which protects the door and lowers overall ownership cost.
Service records from construction and mining fleets show genuine XCMG parts cut unplanned downtime.
XCMG produces the 318502138 bracket with efficient cutting and welding runs that keep production scrap low.
A long service life means fewer replacements, which lowers the material and energy tied to each bracket.
Protecting the door and frame prevents damage and waste, which keeps the operator station usable for the full machine life.
The materials in this part comply with RoHS and REACH requirements for safe handling and responsible recycling.
The 318502138 bracket is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each unit is wrapped to protect the coating and boxed in a strong carton that guards against dust, damp and impact.
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 arm square and the base plate flat until fitting, avoiding the distortion seen in loose storage.
