The shim ensures precise alignment of excavator joint parts, maintains the optimal assembly gap of mechanical structures, improves overall operation flexibility and transmission efficiency, and prolongs the service life of the whole equipment.
As a standard supporting maintenance accessory, it is used for regular replacement of aged, deformed and worn shims of XE2000 excavators. By readjusting component assembly gaps, it restores the original optimal operating accuracy and working performance of the equipment, realizing standardized daily maintenance.
With excellent low-temperature resistance, high-temperature resistance and anti-corrosion performance, the product adapts to extreme working environments in high-altitude, ultra-low temperature and humid regions such as Australia, South America and Central Asia. It maintains stable structural accuracy and working performance in complex extreme climates to ensure continuous and normal operation of excavators.
First, shut down the XE2000 excavator engine completely, lower the bucket to the ground to fix the whole machine stably, and cut off the equipment power supply to avoid accidental startup or component displacement and ensure construction safety.
Verify that the shim’s model (XE2000.02-38), part number (318301296) and selected thickness meet the equipment technical specifications and actual installation gap requirements of the XE2000 excavator.
Visually inspect the shim for structural defects such as deformation, cracks and surface corrosion. Thoroughly clean the installation contact surfaces of pin shafts, shaft sleeves and connecting joints to remove dust, oil stains and rust deposits, ensuring a flat, clean and tight fitting foundation for the shim.
Prepare conventional operating tools such as wrenches, screwdrivers and micrometers in advance for subsequent installation and gap detection work.
Use a wrench to loosen the fixing bolts and fasteners at the boom, arm and bucket pin joint positions, and slightly separate the connected structural parts to reserve a reasonable installation gap for the shim.
Accurately measure the actual assembly gap with a micrometer, select the shim with matching thickness. Adopt the installation principle of thin sheet priority and layered stacking as required, lay the shim flat in the reserved gap to ensure flat placement without inclination, warping or loose fitting.
Fine-tune the shim position to achieve full alignment with the component installation surface, then tighten the fastening bolts in accordance with the standard torque parameters specified in the official XE2000 excavator manual to fix all structural parts firmly.
Re-measure the component assembly gap with a micrometer. The optimal standard gap range is 0.5mm to 1.0mm. Adjust the number or thickness of shims until the gap meets the factory standard.
Start the excavator and keep it running at idle speed, repeatedly operate the boom, arm and bucket mechanisms. If no abnormal noise or jamming occurs, the installation is completed successfully.
Shut down the excavator engine, stabilize the fuselage, and lock the pilot operating lever to prevent accidental movement of the equipment during replacement construction.
Loosen the fastening bolts at the target joint with the old shim, slightly separate the connecting components, and gently take out the worn and aged old shim with a screwdriver. Forbid forced prying and pulling to avoid scratching or damaging precision parts such as pin shafts and shaft sleeves.
Completely clean the equipment installation surface to remove accumulated dust, oil dirt and rust. Inspect pin shafts, shaft sleeves and joint structures for severe wear or damage, and repair or replace faulty parts in a timely manner to ensure subsequent equipment operating stability.
Install the new XE2000.02-38 (318301296) adjusting shim strictly in accordance with the standard installation steps, select the appropriate thickness to ensure the assembly gap reaches the optimal standard, and fasten all bolts to the specified torque.
Complete equipment operation test, check whether the boom, arm and bucket move flexibly without abnormal noise and stagnation. Record the replacement time for subsequent equipment maintenance file reference.
It is strictly forbidden to carry out shim installation and replacement operations when the excavator is running or powered on, so as to avoid personal safety accidents caused by sudden movement of mechanical components.
Do not use shims with unqualified thickness or inconsistent specifications. Unmatched accessories will lead to over-tight or loose fitting of components, easily causing mechanical failure and potential safety hazards.
Ensure the shim is placed flat and fully fitted with the installation surface. Deformed, cracked, rusted or damaged shims are prohibited from being put into use.
After installation, all fastening bolts must be rechecked and tightened to the standard torque to prevent the shim from shifting or falling off during equipment operation.
Store unused spare shims in a dry, clean and ventilated environment to avoid moisture erosion, rust deformation and performance deterioration, ensuring the usability of spare parts.
