OEM 803173593 The XCMG Door Stop Block 803173593 is a genuine cab door limiter that holds the operator door of an XCMG excavator at a fixed open angle.
Issued under the official part number 803173593, the block gives the technician a correctly sized stop that matches the door frame, hinge geometry and mounting holes it was designed for.
The block is formed and machined to the XCMG drawing, so the mounting bolt pattern, stop face and clearance match the cab frame without shims or slotting.
A reinforced rubber or polymer face cushions the door as it swings open, so the impact is absorbed instead of cracking the glass or the frame.
A protective coating resists water, dust and UV light, so the block keeps its shape and finish through wash-down and long outdoor service.
Every block is checked for mounting hole spacing, overall height, stop angle and surface finish before the batch is packed for shipment.
Fitted to cab doors, engine covers and access panels, this stop block keeps panels from swinging wide and damaging nearby parts.
The 803173593 block is produced to the XCMG drawing, so the bolt holes and stop face line up with the cab frame on the first attempt.
Correct stop geometry holds the door at the intended open angle, so the operator can step in and out without the door swinging back.
The cushioning face absorbs impact as the door reaches its limit, so hinges, glass and frame welds are not shocked at every opening.
The body resists water, dust and UV light, so the block does not crumble, harden or crack when the machine works outdoors.
Because the part matches the OEM number, a fitter installs it straight from the bag without shims, drilling or extra spacers.
Correct material hardness keeps the stop firm under vibration, so the door does not chatter or drift past the intended angle.
A sound block also protects the door seal and latch, which keeps the cab closed and weather-tight on dusty or wet sites.
Keeping a spare block on the shelf shortens repair time, so a missing stop does not leave the door swinging into the mirrors.
Each lot begins with certified rubber, polymer or steel stock tested for hardness, compression set and impact strength before forming.
Blocks are molded or machined in polished tooling, so the outline, stop face and hole spacing stay uniform from batch to batch.
Trimming removes flash from the contact face, so the block seats flat against the frame and does not rock on a raised edge.
Inspectors measure hole spacing, height, width and stop angle against a gauge made for this exact part number.
Batch records trace every 803173593 block to its material lot and production run, so a quality question is settled quickly.
A door stop block limits how far a cab door opens, so the panel stops at a set angle instead of swinging into the machine body.
A missing or broken block lets the door swing past its limit, which bends hinges, cracks glass and tears the door seal.
The genuine 803173593 holds the limit firmly, so the door, frame and hinge stay aligned through thousands of open and close cycles.
Correct fit avoids both a block that works loose under vibration and one that sits too proud and holds the door partly open.
A sound stop protects mirrors, handrails and cab trim, which keeps the operator station safe and the machine presentable.
The 803173593 block is installed with a cleaning cloth, a spanner set and a screwdriver during cab or body service work.
Support the door, remove the old block 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 block sitting flat.
Fit the block with the correct bolts, start the threads by hand and align the stop face with the door travel limit.
Tighten to the torque in the service data, so the block stays put without crushing the mounting face or stripping the thread.
Open and close 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 worn face or a cracked body and renew the part before the door over-travels.
Every 803173593 block is produced in an ISO 9001 and ISO 14001 certified plant with traceability from material to carton.
Incoming material is tested for hardness and impact strength, and finished blocks are gauged for hole spacing, height and width.
Each batch is screened for voids, cracks and flash, since these defects cause the block to split or fail under door load.
Post-production checks include visual review, dimensional verification and a trial fit on the XCMG cab frame fixture.
Sample blocks from each batch undergo impact, heat ageing and salt spray tests to confirm damping and corrosion performance.
Cheap copies often use low-grade rubber or thin steel that splits, bends or crushes soon after the door starts swinging against it.
A block with the wrong height or hole spacing can hold the door partly open, work loose or leave the stop face misaligned.
The genuine 803173593 is made to the XCMG drawing, so height, hole spacing, stop 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 door stop block performs reliably in harsh conditions.
Choosing the genuine 803173593 block prevents a small damaged stop from turning into bent hinges or cracked door glass.
A missing block lets the door over-travel, which distorts the frame and breaks the seal that keeps dust out of the cab.
A correctly made block holds firmly, so it does not need repeated tightening and does not wear out the mounting face.
Reliable stops also keep the cab closure intact, 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 803173593 block with efficient molding or machining runs that keep production scrap low.
A long service life means fewer replacements, which lowers the material and energy tied to each stop block.
Protecting the cab door 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 803173593 block is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each block is bagged to protect the contact face 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 block square and the stop face undamaged until fitting, avoiding the distortion seen in loose storage.
