97.5X210mm
The Boom Pin for LiuGong 856 Wheel Loader is a heavy-duty structural pivot pin designed to connect the boom and bucket linkage system, ensuring stable load transfer during lifting and dumping operations.
Manufactured from high-quality alloy steel (40Cr or 42CrMo), the pin is precision-machined, quenched, and tempered to deliver superior hardness, impact resistance, and fatigue strength.
Its 97.5×210 mm size ensures a perfect fit with the LiuGong 856 loader’s boom and bucket assembly, maintaining consistent motion and minimizing joint wear.
Each pin undergoes strict dimensional and surface testing, making it suitable for demanding construction, quarrying, and mining applications.
OEM Fit for LiuGong 856 Loader – Perfect replacement for the original boom or bucket pivot pin.
High-Strength Alloy Steel – Made from 40Cr or 42CrMo with excellent toughness and wear resistance.
Precision Machining – CNC-turned and ground to tight tolerances for smooth fitment with bushings.
Enhanced Surface Hardness – Induction-hardened to HRC 55–60, ensuring long-lasting durability under heavy load.
Corrosion Protection – Optional surface treatments such as chrome plating or black oxide for extended service life.
| Option Type | Available Choices | Description |
|---|---|---|
| Material | 40Cr / 42CrMo / 45# | Selected based on working load and conditions |
| Size | 97.5×210 mm (standard) / custom sizes | OEM & aftermarket dimensions supported |
| Surface Treatment | Chrome plating / Phosphate / Black oxide | Increases rust and wear protection |
| Hardness | HRC 50–60 | Through hardening or surface induction |
| OEM Marking | Available | Laser engraving or stamping upon request |
This boom pin is designed specifically for the LiuGong 856 wheel loader, ensuring perfect alignment and load balance in critical joint locations:
Boom-to-bucket joint — Transfers digging and lifting force
Boom-to-link connection — Provides pivotal motion and structural strength
Hydraulic cylinder ends — Maintains smooth articulation during operation
Its robust heat-treated design ensures maximum wear resistance even under continuous vibration and heavy-duty use.

Our loader pins are manufactured under a strict 18-step process to ensure reliability and precision:
Production planning based on OEM requirements
High-grade alloy steel procurement
Material composition testing
Precision sawing and turning
Heat treatment (quenching and tempering)
CNC machining and grinding
Surface hardening and polishing
Dimensional inspection using 3D CMM
Surface coating application
Final inspection, oiling, and anti-rust packaging
Each pin undergoes 100% dimensional and hardness inspection to meet international standards.
1. Is this boom pin an OEM replacement for LiuGong 856?
Yes. It matches OEM dimensions and tolerances for direct installation without modification.
2. Can you supply matching bushings or pins for other LiuGong models?
Absolutely. We can produce boom pins, bucket pins, and bushings for other models such as LiuGong 835, 842, 870, and customized variants.
3. What’s the difference between 40Cr and 42CrMo materials?
40Cr: Balanced strength and cost-effective for standard applications.
42CrMo: Higher impact resistance, ideal for heavy-duty or mining environments.
4. How is the pin surface treated for anti-corrosion?
Pins can be chrome plated for high wear and rust resistance or phosphated/blackened for cost-efficient protection.
5. What’s the lead time for production?
Normally 15–20 days, depending on quantity. Emergency production for maintenance orders is available on request.
