How to Install an Excavator Telescopic Arm: Step-by-Step Guide 01 Should prepare these: Need 3 people ： 1 as driver and 2 as install man Make sure the excavator have additional pipe line Need Tool: Internal and external plug（M26x1.5H type） 2 sets Internal and external plug（3/4 female type） 2 sets Internal and external plug（1”female type） 2 sets Internal and external plug（19 US flat cut type） 1 sets open spanner: 17-19、18-21、22-24、27-30、30-32（2 sets） 36-41（2 sets） Adjustable wrench:450#、300# double offset ring spanner: 18、21、22、24 Quick wrench and socket Flat-head screwdriver， Phillips screwdriver 10# T-bar, pliers, suspender, thick top bar for shaft, sledgehammer   02 Remove the hydraulic pressure need to turn off the excavator and Remove the pressure from the hydraulic line First (A button on the pressure valve removes the pressure from the tubing Force, if the relief valve does not work, you can remove the liquid Pressure can also be removed from the tank cap)     03 Install the telescopic arm   04 Install the pipe line     05 The telescopic arm already connected     06 Let`s see how to install the bidirectional foot switch Replace the foot pedal switch with Bidirectional     07 The bidirectional foot pedal switch consists of four connector: T, P, A1, and A2. .The T port should be connected to the T port of the excavator's travel valve using a three-way joint to separate the oil flow. Similarly, the P port should be connected to the P port of the travel valve using a three-way connector for oil separation. Finally, the A1 and A2 connectors should be connected to the pilot control connector of the distribution valve.       08 Travel Valve Remove the rubber pad located on the cab floor to reveal the designated installation opening for the bidirectional foot pedal switch. Typically, this opening is situated on the right side of the cab. Find the T port and P port of the travel valve, which corresponds to the T port and P port connected to the foot pedal.   09 link pipe A1 and A2 are connected to the distribution valve. To locate the distribution valve, follow the breaker pipeline and observe where it connects to the distribution valve. Look for joint positions on both sides of the connection or at the corresponding middle position, where the valve covers are visible. Connect A1 and A2 to these two positions respectively. Find corresponding valve covers. The valve cover of the oil inlet pipe is typically connected to A1, while the valve cover of the oil return pipe is connected to A2. In the event of reversed action, simply swap the pipelines connected to A1 and A2.   10 Pipe Connection Diagram   11 after installation , should lube it Apply grease to the pin positions, the arm tube of the telescopic arm，there are many lubrication holes on the telescopic arm can add grease , the telescopic arm also should lube whole body!     Meta Description: Learn how to install an excavator telescopic arm safely and efficiently with this step-by-step guide.

When selecting a two-section telescopic arm, consider the following factors to ensure you get the best performance for your application: Material Quality High-strength steel (such as LG700 or Q355B) offers durability while keeping the arm lightweight. Reinforced pivot points and multi-layer welding enhance structural strength. Excavation Depth & Reach Choose an arm with an optimal telescoping range to suit your worksite requirements. Some high-quality arms provide an additional 20 cm of digging depth compared to standard models. Hydraulic Cylinder Design A double-slider cylinder design helps reduce vibrations and ensures stable movement. Well-sealed cylinders prevent oil leakage and extend service life. Bucket Compatibility Ensure the arm is compatible with different bucket types for various tasks like dredging, deep excavation, or demolition. Ease of Maintenance Look for models with an external bucket cylinder design, making replacements and repairs more convenient. A double-layer hose casing reduces pipeline wear and increases longevity. Manufacturer Reputation & After-Sales Support Website: www.excavatorrockbuckets.com Choose a manufacturer with proven expertise in custom excavator attachments. A reliable supplier should provide technical support, spare parts, and warranties for long-term reliability. ​ More information, pls contact Ada: www.excavatorlongarm.com My Whatsapp: +8615322105263 Tel/Wechat: 0086 15322105263 E-mail: abby@excavatorboomarm.com
