The genuine XCMG Spacer with OEM number 332107464 is a precision-machined positioning component engineered for XCMG articulated dump trucks (AD series). This heavy-duty spacer maintains critical clearances between structural and drivetrain components, ensuring proper alignment of suspensions, axles, and mounting brackets. The 332107464 Spacer is manufactured from corrosion-resistant steel with exact dimensional tolerances, providing reliable load distribution and vibration damping in extreme mining environments.
The XCMG Spacer 332107464 provides accurate positioning between two bolted components, ensuring proper load transfer and preventing distortion. It is used extensively in AD-series trucks for suspension arms, axle stops, and engine mounting brackets.
Improper spacing can lead to premature bushing wear, fastener loosening, and structural cracks. The 332107464 spacer’s precise thickness and flat faces guarantee consistent clamping force distribution.
Field data from mining fleets indicates that trucks fitted with genuine XCMG spacers experience 60% fewer suspension alignment issues and 45% longer bolt joint retention compared to generic or homemade spacers.
The 332107464 spacer is CNC turned from solid 1045 carbon steel bar stock or optionally from 304 stainless steel. This ensures no porosity or internal voids, unlike cast spacers.
The faces are ground to achieve a surface finish of Ra 0.8 µm and parallel within 0.05 mm. This eliminates rocking and provides uniform bolt preload.
The zinc-nickel plating offers excellent corrosion resistance and lubricity, preventing galvanic corrosion with aluminum or steel mating surfaces. Stainless steel version is recommended for highly corrosive environments (e.g., saltwater ports).
Installing the XCMG Spacer 332107464 is straightforward: clean the mating surfaces, position the spacer between components, insert the M24 bolt, and torque to specification (typically 450–500 Nm for suspension joints).
Because the inner diameter is designed for an M24 bolt with a 1.5 mm clearance, the spacer self-centers during assembly. No special tools are required.
The same part number is used across AD45, AD60, AD80, and AD100 models for multiple applications, reducing inventory complexity. A spacer kit (OEM 332107464-KIT) includes four spacers, bolts, and hardened washers.
A missing or incorrect spacer in a suspension joint can cause bolt bending, fastener fatigue, and ultimately joint separation – a safety hazard. The 332107464 spacer maintains proper stack height, allowing bolts to achieve design preload.
Fleet records show that using genuine spacers reduces re-torquing frequency by 75%. The spacer’s smooth faces also protect mating component surfaces from fretting wear.
In axle mounting applications, the spacer ensures correct gear mesh alignment, preventing premature differential failure. A single axle misalignment can cost $25,000 in repairs – the spacer’s cost is negligible in comparison.
Non-genuine spacers are often cut from mild steel pipe, which deforms under load and loses thickness, causing bolt preload loss. Some counterfeits have rough, non-parallel faces that pinch bolts and induce bending stress.
Another issue is incorrect inner diameter: oversized holes allow bolt shank contact, leading to thread damage. Genuine XCMG spacers have a precisely reamed ID with a 0.1 mm clearance over the M24 bolt.
Always look for the XCMG part number stamped into the outer diameter. Genuine packaging includes a certificate of conformance with dimensional measurements. Stainless steel versions have an additional “SS” mark.
Using correctly spec’d spacers like the 332107464 extends the life of bushings, bearings, and fasteners. In a typical AD truck, there are over 50 critical bolted joints requiring spacers. Upgrading to genuine spacers can reduce annual fastener replacement costs by 40%.
The spacer’s corrosion-resistant finish prevents seizing, enabling disassembly without cutting bolts. A seized suspension bolt can take 4 hours to remove; a properly spaced joint takes 30 minutes.
For fleets operating in abrasive conditions, the 332107464’s hard surface resists embedding of dirt, maintaining accurate thickness over years of service.
Every XCMG Spacer 332107464 is produced in ISO 9001:2015 and IATF 16949 certified facilities. Each unit undergoes 100% dimensional inspection (OD, ID, thickness, parallelism) using laser micrometers.
A random sample per batch is subjected to hardness testing and salt spray exposure (720 hours). XCMG provides a 24-month warranty against manufacturing defects, including material flaws or dimensional non-conformance.
For custom applications, XCMG offers spacers in any thickness from 5 mm to 50 mm (in 0.5 mm increments). Contact XCMG parts with your drawing for quotation.
