OEM 800374380 The XCMG Shaft Liner (800374380) is a genuine OEM wear sleeve designed to protect critical rotating shafts from fretting, abrasion, and corrosive attack in the transmissions, final drives, and hydraulic pump assemblies of XCMG articulated dump trucks. This high‑precision liner, identified by part number 800374380, provides a durable, replaceable surface that significantly extends the service life of expensive shaft components, minimising unplanned downtime and reducing total maintenance costs in the harshest mining and construction environments.
Manufactured from premium alloy steel with precision‑ground inner and outer diameters, the 800374380 shaft liner offers exceptional wear resistance, dimensional stability, and fatigue strength. Its advanced heat treatment and superfinished surface ensure low friction and even load distribution, reducing wear on seals, bearings, and mating components.
The 800374380 shaft liner is fully compatible with XCMG ADT series, providing a direct replacement solution that restores original shaft surface integrity, reduces vibration, and ensures reliable power transmission – keeping your fleet operating at peak productivity.
The 800374380 Shaft Liner is purpose‑designed to protect rotating shafts from fretting, abrasion, and corrosion in the high‑stress environments of XCMG articulated dump truck transmissions, final drives, and hydraulic pump drives.
Rotating shafts in ADTs are subjected to continuous high‑torque loads, oscillating motion, and abrasive contaminants such as dust and metal particles, which can cause rapid wear and surface damage.
This genuine XCMG liner provides a replaceable hardened surface that absorbs wear, protecting the expensive shaft from damage and extending its service life by up to 300% compared to unprotected shafts.
Its precision‑ground inner and outer diameters ensure a perfect interference fit with the shaft and housing, eliminating play and reducing vibration that can accelerate seal and bearing wear.
The liner’s advanced heat treatment and superfinished surface reduce friction and heat generation, promoting efficient lubrication and preventing galling under high‑load conditions.
Field data from mining operations shows that genuine XCMG shaft liners reduce shaft‑related downtime by over 50% and significantly extend the interval between major overhauls.
The 800374380 Shaft Liner is a vital component in maintaining the integrity of rotating shafts, directly affecting the reliability and longevity of the entire driveline system.
Worn or damaged shafts can cause seal failure, bearing misalignment, and gear tooth damage, leading to costly repairs and extended machine downtime.
This genuine XCMG liner restores the original shaft diameter and surface finish, ensuring that seals maintain proper contact and bearings operate with correct clearances and preload.
By providing a smooth, wear‑resistant surface, the liner reduces friction and heat, which in turn reduces oil degradation and extends the life of lubricants.
Fleet operators have reported a 40% reduction in seal and bearing replacements after fitting genuine XCMG shaft liners during scheduled overhauls.
Regular inspection of the liner for signs of wear, scoring, or corrosion is essential; any damage requires immediate replacement to prevent shaft damage.
The 800374380 Shaft Liner is manufactured using precision machining, heat treatment, and superfinishing processes to achieve exceptional dimensional accuracy and surface quality.
The alloy steel is forged and then CNC machined to achieve the required inner and outer diameters with tight tolerances, ensuring a consistent interference fit.
XCMG’s engineering team has optimised the liner’s geometry to provide uniform wall thickness and stress distribution, preventing deformation under load.
The through‑hardening and tempering process produces a uniform hardness of 52‑58 HRC, providing excellent wear resistance and toughness.
The superfinishing operation (Ra 0.4‑0.8 µm) reduces friction and promotes proper oil film formation, minimising wear on seals and bearings.
All liners are 100% inspected for dimensional accuracy, surface finish, and hardness to guarantee they meet XCMG’s strict OEM standards.
The 800374380 Shaft Liner is made from SAE 4140 / 42CrMo4 chromium‑molybdenum alloy steel, which offers excellent hardenability, toughness, and fatigue resistance.
The through‑hardening process creates a uniform martensitic structure with a hardness of 52‑58 HRC, providing a wear‑resistant surface that resists scoring and abrasion.
The tempering process relieves internal stresses and improves toughness, preventing cracking or fracture under impact loads.
The zinc‑phosphate coating provides corrosion protection during storage and transport, and also serves as a bond layer for initial run‑in lubrication.
Accelerated wear testing has demonstrated that the liner’s surface hardness and finish reduce wear rates by up to 70% compared to unhardened shafts.
All materials are RoHS compliant and meet stringent environmental standards.
The 800374380 Shaft Liner is designed for professional installation by trained technicians using appropriate tools, including bearing presses and induction heaters.
Begin by disassembling the driveline component to access the shaft, and thoroughly clean the shaft surface and housing bore to remove debris and old lubricant.
Measure the shaft diameter and housing bore to ensure they are within tolerance and free from damage that could affect the liner’s fit.
Carefully press the new 800374380 liner onto the shaft using a suitable sleeve, applying force evenly to avoid distortion, then install the assembly into the housing.
Ensure the liner is fully seated and check the end‑float and bearing preload as per the service manual specifications.
A typical liner replacement can be completed in 1‑2 hours, restoring shaft surface integrity and preventing further wear.
Investing in the 800374380 Shaft Liner delivers significant long‑term savings by extending shaft life, reducing seal and bearing wear, and preventing costly driveline failures.
A single damaged shaft can cost over $5,000 to replace or recondition – this liner prevents that expense by providing a sacrificial wear surface.
Reduced shaft wear also minimises oil contamination from metal particles, extending the life of lubricants and filters.
Lower friction and heat generation improve overall driveline efficiency, saving fuel and reducing operating temperatures.
Field data from a large iron ore mine showed a 45% reduction in driveline maintenance costs after standardising on genuine XCMG shaft liners.
The liner’s robust construction ensures it lasts the full service interval, offering excellent return on investment.
