OEM 800143061 The XCMG 3036460 Spring Washer 800143061 is a genuine OEM lock washer engineered to keep bolted joints tight under vibration on XCMG hydraulic excavators.
Identified by part number 800143061, this factory-made spring washer adds tension between the bolt head and the joint, so the fastener resists loosening.
It is formed from spring-grade carbon steel, heat treated, and hardened so the split ends press against the mating surfaces with consistent force.
Exact OEM inner diameter, outer diameter, thickness, and split height allow direct replacement with the original bolt and torque value.
By adding controlled spring tension, this washer reduces bolt loosening, protects joints from fretting, and keeps hydraulic and structural connections secure.
The 800143061 Spring Washer is stamped from spring-grade carbon steel and heat treated, so it keeps its spring memory under repeated clamping.
The split ends press against the bolt head and joint face, creating friction that resists loosening caused by machine vibration.
Accurate inner diameter, outer diameter, and thickness let the washer seat squarely, so it does not cock or cut into the bolt shank.
A zinc or phosphate coating slows rust and galvanic corrosion, which keeps the washer functional after long outdoor exposure.
Deburred edges protect hands, paint, and mating surfaces during installation and routine service work.
Exact OEM dimensions allow direct replacement with the original bolt and torque, so repairs stay within standard procedure.
Production starts with certified steel strip checked for thickness, width, and spring grade before the press is set up.
Progressive dies blank, pierce, and split the washer in one pass, so the gap and contour stay consistent across the batch.
Hardening and tempering develop the elasticity needed to press the ends apart, and the split height is set to the drawing value.
Inspectors check inner diameter, outer diameter, thickness, split height, and hardness on samples from every production lot.
Batch records let XCMG trace each 800143061 washer back to its steel coil and heat-treat run, so quality questions are resolved fast.
Excavator frames and hydraulic mounts vibrate constantly, and vibration is the main reason bolted joints come loose.
A plain washer cannot store tension, so once the bolt relaxes slightly, clamp force drops and the joint begins to fret.
The genuine 800143061 adds a spring force that compensates for small relaxation, so clamp load stays higher for longer.
That extra tension reduces the chance of bracket movement, hose chafing, and leaks at nearby hydraulic connections.
Consistent fasteners across the machine make maintenance predictable, because technicians know each joint will hold torque.
The 800143061 Spring Washer installs with standard wrenches, adding only moments 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 fully.
Place the washer with the split end facing away from the rotation direction, reinstall the bolt, and torque to the manual value.
After the first shift, recheck torque, because initial settling can relax the fastener slightly and reduce clamp force.
During scheduled maintenance, replace washers that are cracked, flattened, or heavily rusted, and never reuse a deformed washer.
Every 800143061 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 split height.
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, hardness testing, and coating thickness measurement for specification compliance.
Batch samples undergo salt spray and load testing to confirm corrosion resistance and spring tension behaviour in the field.
Generic hardware store spring washers may look similar, but steel grade, hardness, and split height often fall outside the XCMG spec.
A washer that is too soft flattens under torque, and one that is too hard can crack or cut into the joint surface.
The genuine 800143061 is dimensioned and heat treated 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 spring 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 spring 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.
Spring 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 800143061 Spring 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.
