OEM 800142990 The XCMG 64816 A Pin (800142990) is a genuine OEM pivot pin engineered to provide reliable articulation and load transfer for excavator linkage joints, bucket connections, and attachment pivots on XCMG hydraulic excavators. This durable pivot pin, identified by part number 800142990, ensures consistent joint rotation in the most demanding construction, mining, and demolition environments, delivering robust shear and wear resistance that withstands heavy daily use, extreme shock loads, and constant machine vibration.
Manufactured from high-strength alloy steel with precision-controlled heat treatment, a hardened wear surface, and corrosion-resistant plating, the 800142990 pin delivers exceptional shear strength, fatigue endurance, and long-term durability under continuous dynamic loading. Its exact OEM diameter, length, chamfer, and retaining groove configuration guarantee a direct replacement without modification, ensuring seamless integration with your XCMG excavator’s existing linkage bores, bushings, and retention hardware.
The 800142990 pin features a precision-ground cylindrical body that ensures smooth rotation inside bushings, minimising friction and preventing galling or seizure. The hardened surface resists indentation and ovality, while the accurately machined retaining grooves accept the original circlips and keeper plates. By providing a reliable, wear-resistant pivot point, this pin plays an essential role in reducing joint play, preventing bushing damage, lowering maintenance costs, and extending the service life of your excavator’s working equipment.
The 800142990 pivot pin is manufactured from high-strength alloy steel with induction hardening that produces a wear-resistant outer case and a tough, shock-absorbing core. This combination ensures the pin resists surface indentation, ovality, and fatigue cracking even under the heavy impact loads typical of excavator digging and lifting cycles.
The pin’s precision-ground cylindrical body ensures smooth rotation inside bushings, minimising friction and preventing galling or seizure. The controlled surface roughness on the bearing area promotes reliable lubrication film formation, reducing wear on both the pin and the mating bushing.
The hard chrome or zinc plating provides excellent corrosion resistance, protecting the pin from rust, chemical attack, and environmental degradation. The plating also resists abrasion from dust and debris, extending service life in the harshest job site conditions.
The accurately machined retaining grooves accept the original circlips and keeper plates, ensuring positive axial retention without modification. The chamfered ends ease installation and prevent bore damage during insertion.
By providing a reliable, wear-resistant pivot point, the 800142990 pin plays a vital role in reducing joint play, preventing bushing damage, avoiding linkage misalignment, and extending the service life of your excavator’s working equipment.
Whether used for bucket linkage, boom-to-arm joints, or attachment quick-coupler interfaces, the 800142990 delivers dependable pivot performance that keeps your XCMG excavator’s working equipment tight and productive.
The 800142990 pin is produced using advanced forging, turning, grinding, heat treatment, and surface finishing processes that achieve tight tolerances on all critical dimensions, ensuring consistent fit and performance across every unit.
The high-strength alloy steel is selected for its excellent combination of strength, hardenability, and toughness. The induction hardening process produces a controlled case depth with a smooth transition to the tough core, optimising resistance to both wear and shock loading.
The cylindrical body is precision-ground to achieve a fine surface finish and tight diameter tolerance, ensuring proper fit inside bushings. The retaining grooves and chamfers are machined to exacting tolerances for reliable retention and easy installation.
After production, each pin undergoes dimensional inspection, hardness testing, and surface finish verification to ensure it meets XCMG’s stringent quality standards.
Sample units from each production batch are subjected to shear testing, fatigue testing, and corrosion testing to validate long-term durability and performance under harsh environmental conditions.
The result is a pivot pin that delivers consistent, reliable articulation performance throughout the service life of your XCMG excavator.
Pivot pins are critical components in excavator linkage assemblies, providing the rotating connection that transmits force between the boom, arm, bucket, and attachment interfaces. Reliable pin performance is essential for precise digging, lifting, and material handling.
The 800142990 pin ensures that linkage joints articulate smoothly under heavy load, preventing binding, excessive play, and accelerated bushing wear. Its high shear strength safely transmits the extreme forces generated during digging and lifting operations.
Field data from heavy excavation operations shows that machines equipped with genuine XCMG pivot pins experience fewer linkage-related failures and reduced maintenance frequency, improving overall machine reliability and productivity.
The pin’s hardened wear surface and corrosion-resistant finish also protect against the harsh environmental conditions found on construction sites, ensuring that the pin remains functionally reliable and free from excessive wear over years of service.
Regular inspection of pivot pins for signs of wear, scoring, corrosion, or deformation is recommended; any compromised pins should be replaced promptly with genuine 800142990 components.
By maintaining reliable joint integrity, this pivot pin plays a vital role in ensuring safe, productive excavator operation.
The 800142990 pin is designed for straightforward installation using standard workshop tools, minimising downtime and labour costs during routine servicing or component replacement.
Before installation, carefully inspect the pin for any signs of damage, corrosion, or dimensional deviation that may have occurred during storage or transport. Ensure that the linkage bores and bushings are clean and free from debris.
Apply a thin film of suitable grease to the pin surface, then insert it into the aligned bores using a soft-faced mallet or press. Avoid striking the pin directly with a hard hammer, which could damage the chamfer or plating.
After insertion, install the retaining circlips or keeper plates into the grooves and verify that the pin is securely retained. Check that the joint articulates smoothly without binding or excessive play.
During routine maintenance, inspect pins for signs of wear, scoring, corrosion, or deformation. Lubricate the joint at recommended intervals and replace any pin that shows significant wear or damage.
Periodic inspection and replacement of pivot pins as part of a preventive maintenance program will help ensure long-term linkage reliability and operational safety.
Investing in the genuine 800142990 pivot pin delivers significant long-term savings by preventing linkage failures, reducing maintenance frequency, and avoiding costly downtime that can result from pin breakage, joint seizure, or bushing destruction.
A worn or compromised pin can cause excessive joint play, misalignment, and accelerated bushing wear, leading to reduced productivity, premature component failure, and even safety hazards. The 800142990’s hardened wear surface and high shear strength eliminate these issues.
Over a typical 8,000-hour service life, the pin’s durable material and precision manufacturing ensure consistent performance, reducing the need for unscheduled replacements and minimising downtime.
