Liugong SP219686 Dual-Transmission Repair Kit: A "One-Stop Solution" for Engineering Machinery Dual-Transmission System Maintenance

1. Comprehensive coverage of all product categories, enabling “ One-stop procurement ”

The maintenance of the dual-drive system involves various components such as seals, friction parts, bearings, fasteners, and more. Purchasing these parts individually is not only time-consuming and labor-intensive but also increases the risk of encountering component mismatches. LiuGong SP219686 The dual-transmission repair kit is based on LiuGong's mainstream dual-transmission system (such as ZL50 Maintenance requirements for the series-mounted loader's dual-transmission system, conducted “ All-Scenario Component Integration ” : Includes high-quality seals ( O O-rings, oil seals, gaskets, and more 20  Others), crafted from oil-resistant and aging-resistant nitrile rubber and fluororubber materials, perfectly suited for the high-temperature and high-pressure oil environments of dual-transmission systems. These include core friction components (clutch friction plates and steel plates), made from ceramic fiber composite material, ensuring a stable coefficient of friction (<|endofcontentisegmente 0.35–0.4 ), wear resistance life is significantly improved compared to ordinary friction parts 30% ; Equipped with precision bearings (tapered roller bearings, deep groove ball bearings), made from high-carbon chromium bearing steel and treated with vacuum quenching, achieving precision levels of P6 Level up to ensure smooth transmission; also includes specialized fasteners (bolts, nuts, washers) and auxiliary components (filter screens, seal ring installation tools), covering the entire process—from disassembly and repair to reassembly—of the dual-transmission system. No need for multiple purchases or comparing prices from different suppliers—just one repair kit is all you need! 95% The above-mentioned dual-system routine maintenance requirements significantly enhance maintenance efficiency.

2. Precise factory matching, eliminating any discrepancies “ Compatibility Risks ”

The double-transformation system components demand extremely high dimensional accuracy; non-genuine parts are prone to installation issues like jamming and transmission noises due to dimensional deviations, potentially even accelerating system wear. LiuGong SP219686 The dual-transmission repair kit’s components are all designed and manufactured by LiuGong’s original factory, strictly adhering to the original factory drawings and technical standards for the dual-transmission system: sealing parts have dimensional tolerances. ≤0.02mm , achieving a perfect fit with the dual-mechanism system housing and shaft components. 99.8% , effectively preventing oil leakage; tolerances for friction component thickness are controlled within ±0.05mm , precisely matching the clearance with the clutch steel plates according to original factory specifications ( 0.15-0.25mm ), avoiding gear-shifting shocks caused by excessive clearance or friction plate erosion due to insufficient clearance; the inner and outer ring diameters of the bearing achieve precision levels of IT5 The grade ensures that the interference fit between the journal and bearing housing strictly adheres to the original manufacturer's specifications, guaranteeing zero radial runout during operation and minimizing transmission noise. This repair kit is precisely designed to fit LiuGong equipment perfectly. ZL50CN、 CLG856 The mainstream loader dual-transmission system is simultaneously compatible with LiuGong’s platform-derived models. After installation, no additional grinding or adjustments are required—simply restore the original factory performance of the dual-transmission system, effectively eliminating any potential issues. “ Compatibility Risks ”。

3. Rigorous quality control ensures “ Long-lasting and durable ”

After maintenance, the dual-drive system must endure long-term exposure to high torque and elevated oil temperatures—conditions that directly determine the component quality and, consequently, the service life following repair. LiuGong is committed to SP219686 Dual-Shift Repair Kit Implementation “ End-to-End Quality Control ” : During the raw material stage, the seals undergo oil resistance aging tests ( 120℃ Hot oil soaking 1000  Hours, volume change rate ≤5% )、perform friction and wear tests on friction components (simulating heavy-load conditions) 10  Ten thousand gear shifts, wear amount ≤0.1mm )、Bearing life testing (rotational speed 3000 rpm Continuous operation below 2000  No abnormalities detected during the hour; during production, samples are taken from each batch of components for dimensional accuracy testing (using a three-coordinate measuring machine), hardness testing (with a Rockwell hardness tester), and leak-tightness testing (using a pressure testing machine). At the finished-product stage, the repair kits must pass “ Simulated Installation Testing ” , assemble the components onto the dual-transmission system test bench and operate continuously under rated load. 500  Hours were spent verifying transmission efficiency, smoothness of gear shifts, and sealing performance, ensuring that all components meet LiuGong standards. “12 Month / 2000 One-hour warranty ”  Standard. Market-tested, the dual-transmission system repaired using this kit demonstrates an average increase in mean time between failures compared to systems maintained with conventional components. 60% , significantly extending maintenance intervals and reducing subsequent upkeep costs.

4. Convenient maintenance design to reduce “ Operational threshold ”

The dual-drive system has a complex structure, and its maintenance process requires high levels of expertise. LiuGong SP219686 The dual-transformation repair kit emphasizes meticulous design details. “ Ease of maintenance ” : All components are packaged according to the repair and assembly sequence, with clear labels indicating the component name, installation location, and quantity (e.g., “ Transmission input shaft oil seal - 1 Item ““ Clutch friction plate - 6 Piece ” ), maintenance personnel can quickly identify and access components, preventing confusion; equipped with dedicated installation aids (such as oil seal installation guide sleeves and bearing press-fit sleeves) to avoid damaging seals or bearings during installation; a "Maintenance Guide Manual" is included in the package, detailing the disassembly steps for the dual-transmission system along with component installation torque specifications (e.g., bolt tightening torque). 250 ± 10 N ・ m ）、Key information such as the method and dosage for applying sealant to seals is presented with clear illustrations and easy-to-understand explanations. Even maintenance personnel with limited experience can refer to this manual to perform tasks correctly, thereby minimizing rework caused by improper procedures. Additionally, the repair kit comes in a high-strength, moisture-proof package that ensures long-term storage (with a shelf life of [insert duration] under normal temperature and dry conditions). 2  Year), preventing components from getting damp or rusting, and meeting users' needs for spare inventory.

5. Adapts to Multi-Scenario Repairs, Providing Support “ Quickly resuming work ”
