OEM 860190968 The XCMG Lock Washer 860190968 is a genuine OEM locking washer engineered to secure critical fasteners on XCMG hydraulic excavators.
Identified by part number 860190968, this lock washer prevents bolts and nuts from loosening under heavy vibration and shock loads.
It is stamped from high-strength spring steel and formed with precise teeth or split sections that grip the mating surface.
Exact OEM inner diameter, outer diameter and thickness guarantee a direct replacement without modification during repair.
By maintaining bolt preload, this washer protects the drivetrain and extends the service life of the whole machine.
The 860190968 Lock Washer is stamped from high-strength spring steel that resists flattening and fatigue under vibration.
Its split ends bite into the mating surfaces, creating friction that prevents bolts and nuts from rotating loose.
Exact OEM inner diameter, outer diameter and thickness allow a direct replacement without modification, so the washer fits correctly.
The washer maintains bolt preload, preventing joint separation that could damage the engine, pump or drivetrain.
A zinc-plated anti-corrosion coating protects the steel from rust and chemical attack, extending service life in harsh environments.
Because the washer is a genuine XCMG component, it preserves warranty coverage and maintains compatibility with other OEM parts.
Production starts with certified spring steel strip that is checked for thickness, hardness and tensile strength before release.
Washers are stamped and formed on computer-controlled presses that hold inner diameter, outer diameter and split gap to exact tolerances.
After forming, each washer is heat treated, plated and inspected for hardness, flatness and coating thickness.
Batch records let XCMG trace each 860190968 washer back to its raw material lots, so any quality issue can be identified quickly.
Sample washers from each batch undergo compression testing and fatigue testing to prove long-term locking performance.
A lock washer prevents bolts, nuts and pins from rotating loose under vibration and dynamic load.
The 860190968 washer maintains its locking force at both low and high engine speeds, keeping critical fasteners secure.
Secure fasteners protect the flywheel, coupling and transmission from shock loads, reducing the chance of premature failure.
By preventing joint movement, the washer also reduces noise and vibration, improving comfort for the operator.
When the washer works correctly, connected parts stay aligned and the machine frame experiences less stress and cracking.
Inspect the washer during routine service for cracks, flattening or loss of tension, and replace any worn unit with a genuine 860190968 lock washer.
The 860190968 Lock Washer installs with standard hand tools, keeping downtime and labour costs low during repair.
Park the excavator on firm level ground, shut down the engine, and allow the affected assembly to cool.
Remove the fastener, take off the old washer, inspect the bolt and mating surface for wear, and clean all contact areas.
Place the new washer on the bolt, insert the fastener into the hole, and hand-tighten the nut or bolt.
Tighten the fastener to the specified torque, then check that the washer is seated flat and the split ends are engaged.
Start the engine at low idle, check for unusual noise or vibration, and run through full function cycles before returning to work.
Choosing the genuine 860190968 Lock Washer pays back over time by preventing fastener loosening and component damage.
A failed washer can allow bolts to back out, causing misalignment, vibration and costly repairs to the engine or drivetrain.

Incoming spring steel strip is tested for chemical composition, hardness and tensile strength before release to production lines.
During manufacturing, washer dimensions, split gap, hardness and coating thickness are monitored continuously by trained operators.
Post-production checks include dimensional verification, hardness testing and compression testing to confirm each washer meets specification.
Sample washers from each batch undergo fatigue testing and corrosion testing to prove long-term durability and stable locking performance.
Only washers that pass every quality gate are released, so you receive a dependable, high-performance locking component every time.
Cheap aftermarket washers often use lower-grade steel, incorrect thickness or weak spring tension that leads to rapid failure.
Those shortcuts lead to fastener loosening, joint separation and poor reliability in demanding construction and mining conditions.
