OEM 319002858 The XCMG Lock 319002858 is a genuine cab door lock that secures the operator door and turns with the handle on XCMG hydraulic excavators.
Issued under the official part number 319002858, the lock gives the technician a correctly sized unit that matches the door cut-out, handle spindle and striker it is designed for.
The body is formed and machined to the XCMG drawing, so the fixing holes, latch jaw and spindle bore line up with the door shell without filing or slotting.
A matched jaw and striker keep the door closed firmly, so the panel does not rattle or drift open when the machine works on uneven ground.
A protective plating resists water, dust and corrosion, so the lock keeps its movement and finish through wash-down and long outdoor duty.
Every unit is checked for hole spacing, spindle fit, jaw travel and key action before the batch is packed for shipment.
Fitted to cab doors and access panels, this lock keeps the operator station closed, quiet and secure from dust, rain and unauthorised entry.
The 319002858 lock is produced to the XCMG drawing, so the holes and jaw line up with the door shell on the first attempt.
A matched jaw and striker grip the door firmly, so the panel does not rattle, drift open or strain the hinge on rough ground.
The key cylinder turns smoothly, so the operator can lock and unlock the cab with one hand from outside the machine.
The plated finish resists water, dust and wash chemicals, so the lock does not corrode, seize or stain the cab trim.
Because the part matches the OEM number, a fitter installs it straight from the bag without drilling, filing or adding spacers.
Correct material hardness keeps the jaw and body intact under vibration, so the lock does not wear or slip out of engagement.
A sound lock also keeps the door seal compressed, which blocks dust and water from reaching the operator station.
Keeping a spare lock on the shelf shortens repair time, so a failed cylinder does not leave the cab door unsecured.
Each lot begins with certified zinc alloy, steel or polymer tested for hardness, strength and coating adhesion before forming.
Lock bodies are cast or machined in controlled tooling, so the outline, hole pattern and jaw travel stay uniform from batch to batch.
Deburring removes sharp edges from the holes and jaw, so the lock seats flat and does not cut the paint or the door seal.
Inspectors measure hole spacing, spindle fit, jaw travel and finish against a gauge made for this exact part number.
Batch records trace every 319002858 lock to its material lot and production run, so a quality question is settled quickly.
A door lock holds the cab door against its seal, so the operator station stays closed, quiet and secure.
A broken or worn lock lets the door swing open, which disturbs the seal, strains the hinge and leaves the cab unsecured.
The genuine 319002858 keeps the door locked, so the seal holds and dust, rain and noise stay outside the cab.
Correct fit avoids both a lock that releases under vibration and one that grips too hard and damages the striker.
A sound lock protects the door, hinge and seal, which keeps the operator station safe and extends the life of the assembly.
The 319002858 lock is installed with a cleaning cloth, a spanner set and a screwdriver during cab or body service work.
Open the door, remove the old lock and clean the mounting face so no dirt or old thread locker sits under the new part.
Check the frame, striker and door edge for cracks, rust or bent metal, since a damaged face will stop the lock working.
Fit the lock with the correct bolts, start the threads by hand and connect the handle spindle before tightening.
Tighten to the torque in the service data, so the lock stays put without cracking the body or stripping the thread.
Close the door slowly, test the key and adjust the striker so the jaw grips without the door standing proud.
At service intervals, look for loose bolts, a worn jaw or a stiff cylinder and renew the part before the door pops open.
Every 319002858 lock is produced in an ISO 9001 and ISO 14001 certified plant with traceability from material to carton.
Incoming material is tested for hardness and strength, and finished locks are gauged for hole spacing, spindle fit and jaw travel.
Each batch is screened for cracks, burrs and coating defects, since these flaws let the lock jam or release under load.
Post-production checks include visual review, dimensional verification and a trial fit on the XCMG cab door fixture.
Sample locks from each batch undergo cycle, key and salt spray tests to confirm holding force and corrosion performance.
Cheap copies often use soft metal or thin springs, so the jaw slips and the key cylinder seizes soon after installation.
A lock with the wrong hole spacing or jaw angle can bind, misalign the door or fail to grip the striker at all.
The genuine 319002858 is made to the XCMG drawing, so hole pattern, jaw form, cylinder and material match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps fit with OEM cab doors.
Backed by XCMG global quality standards and technical support, this lock performs reliably in harsh conditions.
Choosing the genuine 319002858 lock prevents a worn cylinder from turning into a bent door frame or a damaged seal.
A failed lock lets the door swing open, which strains the hinge and lets dust and water into the operator station.
A correctly made lock holds firmly, so it does not need repeated adjustment and does not wear out the striker.
Reliable locks also keep the cab sealed and secure, which protects the operator and lowers overall ownership cost.
Service records from construction and mining fleets show genuine XCMG parts cut unplanned downtime.
