OEM 800374219 The XCMG Bushing (800374219) is a genuine OEM precision‑manufactured wear component engineered to provide reliable low‑friction support and alignment in pivot joints, suspension linkages, and steering knuckles of XCMG articulated dump trucks. This heavy‑duty bushing, identified by part number 800374219, is designed to withstand high radial loads, oscillating motion, and abrasive contaminants, ensuring smooth articulation and extended service life of critical chassis and driveline assemblies in the most demanding mining and construction environments.
Manufactured from high‑strength alloy steel with precision‑ground inner and outer diameters, the 800374219 bushing offers exceptional wear resistance, dimensional stability, and load‑carrying capacity. Its advanced heat treatment and superfinished surface minimise friction and promote even grease distribution, reducing wear on mating pins and housings while maintaining precise alignment.
The 800374219 bushing is fully compatible with XCMG ADT series, providing a direct replacement solution that restores original joint integrity, reduces play and vibration, and ensures reliable machine handling – keeping your fleet operating safely and productively.
The 800374219 Bushing is purpose‑designed to provide a low‑friction, wear‑resistant bearing surface for pivot pins, suspension links, and steering knuckles, ensuring smooth articulation and accurate alignment.
Articulated dump trucks operate on uneven terrain, subjecting pivot joints to continuous oscillation, high radial loads, and abrasive contaminants that accelerate wear on unprotected mating surfaces.
This genuine XCMG bushing is precision‑ground to exacting tolerances, providing a perfect fit with the pin and housing, eliminating play that can lead to vibration, noise, and accelerated wear.
Its high‑strength alloy steel construction provides excellent resistance to deformation and brinelling, maintaining dimensional stability and load‑carrying capacity under extreme shock loads.
The superfinished surface reduces friction and promotes even lubricant distribution, minimising wear on the bushing and mating pin, and extending the service life of the joint assembly.
Field data from mining operations shows that genuine XCMG bushings reduce joint‑related downtime by over 50% and significantly extend the interval between major suspension overhauls.
The 800374219 Bushing is essential for maintaining correct alignment and load distribution in the articulation joints of XCMG articulated dump trucks, directly influencing machine stability, tyre wear, and safety.
Worn bushings allow excessive play, causing misalignment of suspension and steering components, leading to unstable handling, increased tyre scrub, and accelerated wear of pins and housings.
This genuine XCMG bushing restores original clearances and alignment, ensuring that the machine tracks straight, steers predictably, and articulates smoothly, reducing operator fatigue and improving productivity.
Proper bushing condition also prevents stress concentrations in housings and brackets, reducing the risk of cracking or fatigue failure that could lead to catastrophic breakdowns.
Fleet operators have reported a 30% reduction in suspension‑related repairs and a 20% decrease in tyre replacement costs after fitting genuine XCMG bushings.
Regular inspection of bushings for wear, scoring, or diameter reduction is essential; any signs of wear require immediate replacement to maintain joint integrity.
The 800374219 Bushing is manufactured using precision CNC turning, heat‑treating, and centreless grinding processes to achieve the highest levels of dimensional accuracy and surface quality.
The alloy steel is forged to refine the grain structure, then machined to exacting tolerances, with critical diameters held to ISO h6 or better to ensure consistent fitment.
XCMG’s engineering team has optimised the bushing’s geometry, including chamfer and radius details, to eliminate stress concentrations and facilitate easy installation.
The through‑hardening and tempering process produces a uniform hardness of 38‑42 HRC, providing an excellent balance of wear resistance and toughness to withstand impact loads.
The final centreless grinding operation produces a mirror‑like surface finish (Ra ≤ 0.8 µm) that reduces friction and promotes proper oil film formation, minimising wear and extending service life.
All bushings are 100% inspected for diameter, straightness, roundness, and surface finish to guarantee they meet XCMG’s strict OEM standards.
The 800374219 Bushing is crafted from SAE 4140 / 42CrMo4 chromium‑molybdenum alloy steel, which offers excellent hardenability, toughness, and fatigue resistance, ideal for high‑load pivot applications.
The through‑hardening process creates a uniform martensitic structure with a hardness of 38‑42 HRC, providing a wear‑resistant surface that resists scoring and galling while maintaining core toughness.
The tempering process relieves internal stresses and improves ductility, preventing brittle fracture under shock loads from sudden impacts or articulation.
The zinc‑phosphate coating provides corrosion protection during storage and transport, and also serves as a base for initial lubrication, reducing friction during run‑in.
Accelerated wear testing has demonstrated that the bushing’s surface hardness and finish reduce wear rates by up to 60% compared to non‑hardened bushings, significantly extending joint service life.
All materials are RoHS compliant and meet stringent environmental standards.
The 800374219 Bushing is designed for straightforward replacement during regular maintenance, requiring only basic hand tools and proper alignment.
Begin by safely supporting the machine and relieving any load on the joint, then remove the retaining hardware and extract the old bushing using a suitable press or drift.
Thoroughly clean the bore and inspect the housing for wear or damage; if necessary, ream or hone the bore to the correct size for a proper interference fit.
Lubricate the new 800374219 bushing and carefully press it into the bore using a suitable sleeve and press, ensuring it is fully seated and square.
After installation, check the inner diameter and alignment, then reassemble the pin and associated components, torquing all fasteners to specification.
A typical bushing replacement can be completed in under 1 hour, restoring joint precision and preventing further wear.
Investing in the 800374219 Bushing delivers significant long‑term savings by preventing joint wear, reducing pin and housing damage, and avoiding costly downtime.
A single worn bushing can cause severe pin and housing damage, with repair costs often exceeding $2,000 – this genuine bushing prevents that outcome.
By maintaining precise alignment, the bushing reduces tyre scrub and uneven wear, extending tyre life and lowering operating costs.
Reduced friction and play also improve fuel efficiency by minimising parasitic losses in the driveline and steering system.
Field data from a large limestone quarry showed a 45% reduction in suspension maintenance costs after standardising on genuine XCMG bushings.
The bushing’s robust construction ensures it lasts the full service interval, offering excellent return on investment.
