OEM 801974528 The XCMG Upper Door Latch 801974528 is a genuine cab door lock that holds the operator door closed and secure on XCMG hydraulic excavators.
Issued under the official part number 801974528, the latch gives the technician a correctly sized lock that matches the door frame, striker and handle linkage it is designed for.
The body is formed and machined to the XCMG drawing, so the mounting holes, latch jaw and striker line line up with the cab frame without slotting or shims.
The latch jaw grips the striker firmly, so the door stays closed and does not rattle or pop open when the machine works on uneven ground.
A protective plating resists water, dust and corrosion, so the latch keeps its movement and finish through wash-down and long outdoor duty.
Every unit is checked for hole spacing, jaw travel, handle effort and surface finish before the batch is packed for shipment.
Fitted to cab doors and access panels, this upper latch keeps the operator station closed, quiet and sealed from dust and weather.
The 801974528 latch is produced to the XCMG drawing, so the holes and jaw line up with the cab frame on the first attempt.
A firm jaw grip keeps the door closed, so the panel does not rattle, pop open or drift when the machine works on uneven ground.
The mechanism moves freely at the handle, so the operator can open and close the door with one gloved hand from inside the cab.
The plated finish resists water, dust and wash chemicals, so the latch 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 striker intact under vibration, so the latch does not wear or slip out of engagement.
A sound latch also keeps the door seal compressed, which blocks dust and water from reaching the operator station.
Keeping a spare latch on the shelf shortens repair time, so a broken lock does not leave the cab door swinging open.
Each lot begins with certified steel, zinc alloy or polymer tested for hardness, strength and coating adhesion before forming.
Bodies are formed and assembled 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 latch seats flat and does not cut the paint or the door seal.
Inspectors measure hole spacing, jaw travel, handle effort and finish against a gauge made for this exact part number.
Batch records trace every 801974528 latch to its material lot and production run, so a quality question is settled quickly.
A door latch holds the cab door against its seal, so the operator station stays closed, quiet and weather-tight.
A broken or worn latch lets the door swing open, which disturbs the seal, strains the hinge and endangers the operator.
The genuine 801974528 keeps the door latched, so the seal holds and dust, rain and noise stay outside the cab.
Correct fit avoids both a latch that releases under vibration and one that grips too hard and damages the striker.
A sound latch protects the door, hinge and seal, which keeps the operator station safe and extends the life of the assembly.
The 801974528 latch is installed with a cleaning cloth, a spanner set and a screwdriver during cab or body service work.
Support the door, remove the old latch 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 latch working.
Fit the latch with the correct bolts, start the threads by hand and connect the handle rod before tightening.
Tighten to the torque in the service data, so the latch stays put without crushing the body or stripping the thread.
Close the door slowly and adjust the striker so the jaw grips without the door standing proud or rubbing the seal.
At service intervals, look for loose bolts, a worn jaw or a stiff handle and renew the part before the door pops open.
Every 801974528 latch 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 latches are gauged for hole spacing, jaw travel and finish.
Each batch is screened for cracks, burrs and coating defects, since these flaws let the latch jam or release under load.
Post-production checks include visual review, dimensional verification and a trial fit on the XCMG cab door fixture.
Sample latches from each batch undergo cycle, vibration and salt spray tests to confirm holding force and corrosion performance.
Cheap copies often use soft metal or thin springs that wear quickly, so the jaw slips and the door starts to pop open.
A latch with the wrong hole spacing or jaw angle can bind, misalign the door or fail to grip the striker at all.
The genuine 801974528 is made to the XCMG drawing, so hole pattern, jaw form, linkage 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 latch performs reliably in harsh conditions.
Choosing the genuine 801974528 latch prevents a worn lock from turning into a bent door frame or a damaged seal.
A failed latch lets the door swing open, which strains the hinge and lets dust and water into the operator station.
A correctly made latch holds firmly, so it does not need repeated adjustment and does not wear out the striker.
Reliable latches also keep the cab sealed, which protects the operator and lowers overall ownership cost.
Service records from construction and mining fleets show genuine XCMG parts cut unplanned downtime.
XCMG produces the 801974528 latch with efficient forming and assembly runs that keep production scrap low.
A long service life means fewer replacements, which lowers the material and energy tied to each latch.
Keeping the cab door closed protects the seal and frame, 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.
