OEM 800167079 The XCMG 205059 Washer 800167079 is a genuine OEM flat washer engineered to distribute clamp load and protect bolted joint surfaces on XCMG hydraulic excavators.
Identified by part number 800167079, this factory-stamped washer sits under bolt heads and nuts to spread pressure across brackets, panels, and castings.
It is punched from high-grade carbon steel strip, deburred for smooth seating, and coated to resist rust, mud, and hydraulic fluid splash.
Exact OEM inner diameter, outer diameter, and thickness allow direct replacement without reaming, filing, or stacking extra shims on site.
By keeping clamp load uniform, this washer holds torque longer and protects nearby components from vibration-induced loosening.
The 800167079 Washer is stamped from carbon steel strip that keeps its thickness and flatness under the high clamp loads used on excavator frames.
Concentric inner and outer diameters let the washer sit centred on the bolt, so the load ring is uniform instead of heavy on one side.
Deburred edges protect paint, wiring insulation, and technician hands, and they prevent stress risers that can start cracks in soft panels.
A zinc or phosphate coating slows rust and galvanic corrosion, which keeps the joint stack height stable through wet seasons.
Correct thickness means bolts achieve full thread engagement without bottoming out or leaving too few threads in the nut.
Exact OEM dimensions allow direct replacement in any bolted joint, which avoids improvisation and keeps repairs to standard procedure.
Each production run starts with a certified coil that is checked for thickness, width, and hardness before the press is set up.
Progressive dies blank, pierce, and trim the washer in one pass, so hole position and outer contour stay concentric throughout the batch.
Parts go through tumbling and edge treatment to remove burrs, then into coating, where thickness and adhesion are controlled.
Inspectors sample every lot for inner diameter, outer diameter, thickness, and flatness using calibrated gauges and a reference plate.
Traceability records tie each 800167079 washer to its steel coil and press run, so deviations can be traced and corrected without delay.
Excavators shake constantly, and every bolted joint goes through thousands of load reversals during a single shift.
A washer that is too thin deforms, which drops bolt tension and lets the joint fret, crack, or leak at a nearby seal.
The genuine 800167079 keeps the correct stack height and contact area, so clamp force remains stable between service intervals.
Spreading the load also protects aluminium covers, thin steel panels, and cast housings from denting and stress cracking.
Consistent fasteners across the machine make maintenance predictable, because technicians know each joint will torque correctly.
The 800167079 Washer installs with standard wrenches, so replacement adds only minutes to a normal service job.
Park the excavator on flat ground, lower the attachment, release hydraulic pressure, and lock out the machine before work.
Loosen and remove the fastener, then clean rust, paint, and debris from the mating face so the new washer seats completely flat.
Slide the washer over the bolt or stud, reinstall the fastener, and tighten it in the sequence and torque value stated in the manual.
After the first working shift, recheck torque on the joint, because initial settling can relax the fastener slightly.
During scheduled maintenance, replace washers that show flattening, cracking, or heavy rust, and never reuse a deformed washer.
Every 800167079 washer is produced in an ISO 9001 and ISO 14001 certified plant, with documented material and process control.
Incoming steel is checked for grade and thickness, while finished washers are measured for both diameters and for flatness.
During production, the press operator monitors die condition and sample dimensions so drift is caught before parts leave the line.
Post-production checks include visual inspection, coating thickness measurement, and a seating test on a flat reference surface.
Batch samples undergo salt spray exposure and compression testing to confirm corrosion resistance and load-spreading behaviour.
Generic hardware store washers may look similar, but thickness and hardness often fall outside the XCMG specification.
A washer that is too soft crushes under torque, and one that is too thin lets the bolt head dig into the panel surface.
The genuine 800167079 is dimensioned and coated to XCMG drawings, so it performs exactly like the original in every joint.
Using genuine XCMG fasteners also keeps warranty coverage intact and avoids mismatched hardware on critical mounting points.
Backed by XCMG quality control and technical support, this washer gives predictable performance in the toughest applications.
Buying the correct washer costs little, but omitting it can cost far more when a bracket loosens or a mount cracks.
Loose joints allow hoses to move, and moving hoses chafe, which leads to leaks and unplanned hydraulic repairs.
Durable steel and stable coating mean each washer survives multiple service cycles, so stock consumption stays low.
Reliable joints also protect brackets, panels, and castings, lowering overall ownership costs for machine owners.
Maintenance teams using genuine XCMG hardware report fewer rework jobs and fewer torque rechecks after repairs.
Steel washers are fully recyclable, and XCMG production processes are designed to minimise scrap and energy use.
Because the washer lasts many service cycles, fewer parts are consumed and less packaging waste is generated over time.
Properly torqued joints reduce oil and coolant leaks, which helps protect soil and water on construction sites.
Materials and coatings used in this component meet RoHS and REACH requirements for safe handling and disposal.
The 800167079 Washer is stocked in XCMG regional distribution centres across North America, Europe, Asia, and Australia.
Units are bagged and boxed in moisture-resistant packaging so they arrive clean, dry, and free from coating damage.
Fleet buyers can combine washer orders with other parts in one shipment, which reduces freight and paperwork effort.
Stock visibility tools help planners confirm availability quickly, so service teams are not delayed by missing hardware.
Protected packaging keeps the factory finish intact until the washer is fitted on the machine.
