This OEM safety pin, identified by part number 805640036, is manufactured from high‑strength alloy steel with a precision‑machined shaft diameter of 12 mm and a usable length of 55 mm, delivering reliable retention under extreme loads.
Designed to withstand the severe vibration, shock, and abrasive conditions of mining, quarrying, and construction, the 805640036 safety pin ensures that critical attachments remain securely locked, preventing accidental disengagement and enhancing operator safety.
Its robust construction and corrosion‑resistant finish make it the ideal replacement for worn or damaged locking pins on XCMG articulated dump trucks and similar heavy machinery.
The 805640036 Safety Pin 12×55 is a precision‑engineered locking pin designed to provide fast, secure attachment and release of implement components on XCMG articulated dump trucks.
This genuine OEM safety pin is manufactured from high‑strength alloy steel and heat‑treated to deliver excellent shear strength, fatigue resistance, and wear characteristics.
The pin’s 12 mm shaft diameter and 55 mm overall length are precisely matched to XCMG linkage and bucket pivot points, ensuring a snug fit and positive locking.
A spring‑loaded detent ball at the end of the shaft provides a positive locking action, preventing accidental withdrawal while allowing quick manual release when required.
The ring handle offers a secure grip for installation and removal, even when wearing heavy gloves, making it ideal for field maintenance and attachment changes.
In XCMG articulated dump trucks, safety pins are used extensively to secure bucket linkages, hydraulic cylinder clevis pins, and attachment pivot points, ensuring that critical components remain engaged during operation.
The 805640036 pin is typically installed through a clevis or lug, where it acts as a positive mechanical stop, preventing rotation or axial movement of the connected parts.
Without a properly functioning safety pin, attachments can become loose, leading to loss of control, component damage, and serious safety hazards.
The spring‑loaded detent ball ensures that the pin remains securely in place even under high vibration, while still allowing for quick removal when needed for maintenance or attachment changes.
Regular inspection and timely replacement of worn or damaged pins with genuine XCMG parts like the 805640036 are essential for maintaining safe and reliable machine operation.
The 805640036 safety pin is precision‑machined from SAE 4140 alloy steel, offering an excellent balance of strength, toughness, and wear resistance.
The shaft is ground to a tight tolerance of ±0.05 mm, ensuring a precise fit in the mating bore and minimising play that could lead to accelerated wear.
The detent ball mechanism is engineered with a corrosion‑resistant stainless steel ball and a high‑cycle spring, providing consistent locking force over thousands of insertion cycles.
The ring handle is forged integrally with the shaft, eliminating potential failure points and providing a robust, comfortable grip.
A zinc‑plated and yellow chromate finish provides excellent corrosion resistance, protecting the pin from rust and pitting even in wet and salty environments.
The 805640036 safety pin is manufactured from SAE 4140 chromoly steel, a material known for its high hardenability, toughness, and fatigue strength.
The material undergoes a precise heat‑treatment process including austenitizing, oil quenching, and tempering to achieve a hardness of 38‑42 HRC.
This heat treatment provides an optimal combination of strength and ductility, ensuring that the pin can withstand high shear loads without fracturing or deforming.
The controlled grain structure of the material ensures consistent mechanical properties across the entire cross‑section, eliminating weak points.
This advanced material science ensures that the 805640036 safety pin delivers reliable performance over thousands of operating hours, even under the most demanding conditions.
The 805640036 safety pin is used extensively in XCMG articulated dump trucks and other heavy equipment operating in surface mining, underground mining, and large‑scale construction.
It is commonly installed in bucket linkage pivot points, hydraulic cylinder clevis pins, and implement attachment lugs, where quick and secure pin retention is essential.
The pin’s 12 mm diameter and 55 mm length are ideal for medium‑duty connections, providing sufficient shear capacity for most attachment applications.
Its robust construction and corrosion‑resistant coating make it suitable for use in dusty, wet, and high‑vibration environments common in mining and quarrying operations.
The 805640036 pin is also compatible with other XCMG equipment, including wheel loaders and excavators that use the same pin diameter and length specifications.
Every 805640036 safety pin is manufactured in an ISO 9001‑certified facility under strict quality control procedures.
Incoming raw materials are tested for chemical composition and mechanical properties to ensure they meet the required specifications.
During production, each pin is inspected for dimensional accuracy, including shaft diameter, length, and ring handle geometry, using precision measuring equipment.
Finished pins are subjected to hardness testing and proof load testing to verify that they meet the specified shear strength and fatigue life requirements.
Salt‑spray testing per ISO 9227 confirms the corrosion resistance of the zinc plating, ensuring long‑term durability in harsh environments.
This comprehensive quality assurance programme guarantees that every 805640036 safety pin meets XCMG’s exacting standards for safety and reliability.
The 805640036 safety pin is designed as a direct replacement for the original pin on XCMG articulated dump trucks, including models XDA30, XDA40, XDA45, XDA45U, XDA60, TA30, AD45, AD60, and other variants.
Its 12 mm diameter and 55 mm length match the factory bore and clearance specifications, ensuring a secure, snug fit without excessive play.
The pin is supplied with a protective oil coating to prevent corrosion during storage and handling, ready for immediate installation.
For cross‑brand applications, verify that the bore diameter, length, and detent ball location are compatible with your specific linkage or attachment.
Always consult the parts manual to confirm the correct safety pin for your machine to ensure proper fit and function.
Proper installation of the 805640036 safety pin is essential for secure attachment retention. Begin by inspecting the bore and mating surfaces for burrs, wear, or debris, and clean thoroughly.
Insert the pin through the aligned holes, ensuring that the detent ball is oriented to engage with the locking groove or hole in the mating component.
Push the pin fully into position until the detent ball snaps into place, indicating positive locking. The ring handle should sit flush against the component surface.
To remove, pull the ring handle firmly while applying slight axial pressure to disengage the detent ball, then withdraw the pin.
During routine maintenance, inspect the pin for signs of wear, corrosion, or deformation. Check the detent ball for smooth operation and spring tension.
Replace the pin immediately if the detent ball fails to lock, the shaft shows excessive wear, or the ring handle is damaged.
Always use genuine XCMG safety pins to ensure correct material quality and dimensional accuracy, and avoid reusing pins that have been bent or overstressed.
The 805640036 safety pin complies with SAE J200 and ASTM A29 standards for alloy steel material properties and dimensional tolerances.
