OEM 319003901 The XCMG Lock Housing 319003901 is a genuine machined housing that carries the latch mechanism and handle linkage inside the cab door of XCMG excavators.
Issued under the official part number 319003901, the housing gives the technician a correctly sized body that matches the door cut-out, bolt pattern and striker line it was designed for.
The body is formed and machined to the XCMG drawing, so the mounting holes, internal bore and handle opening line up with the door shell without filing or slotting.
The internal cavity holds the latch parts in the correct position, so the jaw, spring and rod move freely instead of binding against a warped case.
A protective plating resists water, dust and corrosion, so the housing keeps its shape and finish through wash-down and long outdoor duty.
Every unit is checked for hole spacing, cavity depth, opening size and surface finish before the batch is packed for shipment.
Fitted to cab doors and access panels, this housing keeps the latch assembly supported, aligned and protected from dirt and moisture.
The 319003901 housing is produced to the XCMG drawing, so the holes and openings line up with the door shell on the first attempt.
A stable cavity keeps the latch parts in place, so the jaw, spring and rod move freely without binding or rattling inside the door.
Rigid walls hold the mechanism square, so the handle rod does not deflect and the door latches with a firm, repeatable click.
The plated finish resists water, dust and wash chemicals, so the housing does not corrode or stain the cab trim over time.
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 mounting points intact under vibration, so the housing does not crack loose on rough ground.
A sound housing also shields the latch from dust and water, which protects the moving parts and keeps the door secure.
Keeping a spare housing on the shelf shortens repair time, so a cracked case does not leave the cab door unlatched.
Each lot begins with certified zinc alloy, steel or polymer tested for hardness, strength and coating adhesion before forming.
Housings are cast or machined in controlled tooling, so the outline, hole pattern and cavity depth stay uniform from batch to batch.
Deburring removes sharp edges from the holes and cavity rim, so the housing seats flat and does not cut hands or the door seal.
Inspectors measure hole spacing, cavity depth, opening size and finish against a gauge made for this exact part number.
Batch records trace every 319003901 housing to its material lot and production run, so a quality question is settled quickly.
A lock housing holds the latch parts inside the cab door so the jaw, spring and handle rod work together as one unit.
A cracked or worn housing lets the mechanism shift, which jams the latch, breaks the rod and leaves the door unable to close.
The genuine 319003901 keeps the mechanism aligned, so the door latches firmly and the seal stays compressed on all sides.
Correct fit avoids both a housing that sits proud and rubs the striker and one that lets the mechanism rattle loose.
A sound housing protects the door, latch and seal, which keeps the operator station safe and extends the life of the assembly.
The 319003901 housing is installed with a cleaning cloth, a spanner set and a screwdriver during cab or body service work.
Support the door, remove the old housing and clean the mounting face so no dirt or old thread locker sits under the new part.
Check the door shell, striker and rod for cracks, rust or bent metal, since a damaged face will stop the housing sitting flat.
Transfer the latch parts into the new housing, fit the unit to the door and start the bolts by hand before tightening.
Tighten to the torque in the service data, so the housing stays put without crushing the case or stripping the thread.
Close the door slowly and check that the handle, rod and jaw move freely without the door standing proud or rubbing the seal.
At service intervals, look for loose bolts, a cracked case or a stiff handle and renew the part before the door fails to latch.
Every 319003901 housing 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 housings are gauged for hole spacing, cavity depth and openings.
Each batch is screened for cracks, voids and coating defects, since these flaws let the housing split or the mechanism jam.
Post-production checks include visual review, dimensional verification and a trial fit on the XCMG cab door fixture.
Sample housings from each batch undergo load, vibration and salt spray tests to confirm strength and corrosion performance.
Cheap copies often use porous castings or thin walls, so the housing cracks at the bolt holes soon after installation.
A housing with the wrong cavity depth or opening can jam the mechanism, misalign the jaw or leave the handle rod fouling.
The genuine 319003901 is made to the XCMG drawing, so outline, holes, cavity 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 housing performs reliably in harsh conditions.
Choosing the genuine 319003901 housing prevents a cracked case from turning into a jammed latch or a bent door frame.
A failed housing lets the mechanism shift, which breaks the rod and leaves the door unable to close or seal.
A correctly made housing holds the parts firmly, so it does not need repeated adjustment and does not wear out the door shell.
Reliable housings 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 319003901 housing with efficient casting or machining runs that keep production scrap low.
A long service life means fewer replacements, which lowers the material and energy tied to each housing.
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.
The 319003901 housing 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 cavity and openings undamaged until fitting, avoiding the distortion seen in loose storage.
