Fabricated from premium structural steel and processed with standardized heat treatment and professional surface anti-corrosion technology, the shim boasts superior flatness, ultra-tight dimensional tolerance and outstanding wear resistance, which fully matches the original mechanical design parameters of the XE2000 excavator. As an indispensable protective component for excavator connection systems, it effectively reduces friction and abrasion between mating parts, lowers operational noise, improves mechanical transmission efficiency, and sustains stable, safe and long-term operation of XE2000 excavators in rigorous mining and engineering construction environments.
Manufactured via advanced CNC precision machining technology, this adjusting shim features consistent thickness distribution and superior flatness with a tolerance of ±0.01mm, achieving a perfect fit with original equipment dimensions. It can precisely fill assembly gaps between mechanical parts, effectively eliminating component loosening, position deviation and assembly errors during excavator high-load operation.
Adopting high-grade high-carbon structural steel as the base material, the shim undergoes rigorous heat treatment reinforcement, with hardness stabilized at 70-90 HRB. The optimized material and processing technology enable it to withstand long-duration friction, heavy-load impact and continuous mechanical extrusion without structural deformation or damage, delivering reliable long-cycle service performance.
Developed in strict accordance with the original factory design standards and installation parameters of the XE2000 heavy-duty mining excavator, the shim fully conforms to the equipment’s joint installation dimensions and gap design specifications. It requires no cutting, drilling or other secondary processing, supporting direct on-site installation and replacement, which greatly shortens maintenance cycles and reduces labor and time costs.
The product surface is treated with anti-rust oil coating or hot-dip galvanizing protection, which effectively resists rusting, oxidation and chemical corrosion caused by dust, humidity, lubricating grease and other harsh on-site factors. It maintains stable physical performance in high-dust, humid and high-temperature mining operation scenarios, adapting to complex and changeable construction environments.
With a lightweight and ultra-thin integrated structure, the shim is easy to carry and operate. The whole installation and replacement process only requires conventional hand tools, and no professional equipment or complex technical operations are needed. General maintenance personnel can complete the entire operation efficiently, realizing rapid equipment maintenance and recovery.
By precisely adjusting assembly gaps and compensating for natural wear of mechanical parts, the shim effectively protects high-value core components such as pin shafts, shaft sleeves and movable joints from premature aging and failure. It significantly reduces equipment failure frequency, lowers daily maintenance costs and extends the overall service life of excavator key components.

The XE2000 adjusting shim (Model: XE2000.02-36, Part No.: 318301294) is a special supporting spare part for XE2000 heavy-duty mining crawler excavators. It is widely used in multiple engineering and mining scenarios to stabilize the operating state of the excavator’s mechanical transmission and connection system, with specific application scenarios as follows:
In open-pit coal, iron ore and other mineral mining projects, the shim is used to fine-tune the assembly gap of XE2000 excavator’s boom, arm and bucket movable joints. It compensates for mechanical wear caused by long-term heavy-load operation and frequent friction, prevents joint loosening and operational jitter, and ensures stable equipment performance in high-dust and high-vibration mining environments.
During hard rock excavation, crushing and aggregate processing operations, the product calibrates the installation alignment of the excavator’s movable components. It fills assembly gaps generated by rock impact and long-term mechanical loss, effectively reduces equipment operating noise, and avoids premature wear and damage of pin shafts and shaft sleeve components.
It is applicable to key engineering scenarios such as dam construction, highway and railway foundation paving, and port expansion. The shim maintains precise alignment and optimal gap matching of excavator joints, improves the overall working efficiency of mechanical operations, and effectively extends the service life of core equipment components.
Serving as a standard replacement accessory for daily maintenance of XE2000 excavators, it can replace deformed, worn or failed old shims, reset the standard assembly gap of mechanical joints, and restore the optimal working precision and operating state of the equipment.
With excellent low-temperature resistance, high-temperature stability and anti-corrosion performance, the shim adapts to extreme working conditions in high-altitude, ultra-low temperature and humid regions such as Australia, South America and Central Asia. It maintains stable structural and dimensional performance under extreme environments to guarantee normal operation of excavators.
Cut off the engine power of the XE2000 excavator completely, place the bucket stably on the ground to fix the equipment position, and implement power-off protection measures to ensure construction safety before operation.
Verify the consistency of the shim’s model (XE2000.02-36), part number (318301294) and thickness specification with the equipment’s original parameters and actual on-site gap installation requirements.
Inspect the appearance of the new shim to exclude defective products with deformation, cracks, surface corrosion and other quality problems. Thoroughly clean the installation surfaces of pin shafts, shaft sleeves and joints to remove dust, oil stains and rust impurities.
Prepare conventional operating tools such as wrenches, screwdrivers and micrometers for subsequent installation and gap detection work.
Use a wrench to loosen the fixing bolts of the excavator’s boom, arm or bucket pin joints, and slightly separate the connected mechanical components to reserve sufficient space for shim installation.
Measure the actual assembly gap between components accurately with a micrometer, select a shim with matching thickness (adopt the thinnest specification first, and stack multiple shims appropriately if necessary), and lay the shim flat in the gap to ensure full fitting without skew or gap.
Adjust the shim position to make it completely fit the component installation surface, then fasten the fixing bolts according to the standard torque parameters specified in the XE2000 excavator official manual to firmly fix the components and shims.
Recheck the assembly gap with a micrometer after installation; the optimal standard gap range is 0.5-1.0mm. Adjust the number or thickness of shims in time if the gap does not meet the standard until the qualified gap value is achieved.
Start the excavator for idling operation, and flexibly operate the boom, arm and bucket mechanisms. If no abnormal noise or jamming occurs during operation, the installation is confirmed successful.
Turn off the excavator engine completely, stabilize the equipment body, and lock the pilot control lever to prevent accidental displacement of the equipment during replacement.
Loosen the fastening bolts of the target joint with the old shim, slightly separate the matching components, and gently take out the worn and failed old shim with a screwdriver. Forbid forced prying and pulling to avoid scratching or damaging mechanical components.
Perform comprehensive cleaning on the installation fitting surface to remove accumulated dust, oil dirt and rust. Inspect pin shafts, shaft sleeves and joint components for severe wear and damage, and repair or replace faulty parts in a timely manner as required.
Install the new standard shim (XE2000.02-36, 318301294) in strict accordance with the standard installation steps, select the appropriate thickness specification to ensure the assembly gap reaches the optimal standard, and fasten the bolts in place.
Carry out equipment operation test to confirm that the boom, arm and bucket move smoothly without abnormal noise or stuck failure. Record the replacement date and related parameters for subsequent equipment maintenance filing and reference.
It is strictly prohibited to carry out shim installation and replacement operations when the excavator is running or powered on, so as to prevent personal safety accidents caused by sudden movement of mechanical components.
Do not use shims with unqualified thickness or inconsistent models, so as to avoid assembly over-tightness or looseness, which may lead to mechanical jamming, vibration and other equipment failures.
Ensure the shim is laid flat and closely attached to the installation surface during operation; deformed, cracked or corroded shims are forbidden to be put into use.
After the completion of installation and replacement, a secondary inspection of bolt torque must be carried out to prevent the shim from falling off during equipment operation.
Store unused spare shims in a dry and clean indoor environment to avoid moisture erosion, rust and structural deformation.
