29561880 piston-c3/c4 (01-all) Allison spare parts

29561880 piston-c3/c4 (01-all) Allison spare parts

The 29561880 piston-c3/c4 (01-all) is the core actuator of the Allison transmission clutch system, essentially the “power transmission core” of the clutch. It boasts four core advantages: reliable sealing, wear resistance, durability, wide compatibility, and sensitive response. It precisely matches the entire Allison transmission series, with a focus on the 3000, 4000, 5000, and 6000 series heavy-duty transmissions. This aligns with Allison’s positioning as the “King of Heavy-Duty Transmissions” in heavy-duty transmissions. It is widely used in heavy-duty equipment equipped with Allison transmissions, including heavy trucks, mining machinery, oilfield equipment, and construction machinery. It is particularly suitable for heavy-duty scenarios requiring frequent shifting and high torque transmission, serving as a crucial component for controlling the engagement and disengagement of the C3/C4 clutches, ensuring smooth gear shifting, and guaranteeing efficient power transmission.
The 29561880 piston-c3/c4 (01-all) is manufactured strictly according to original factory specifications, using integrated precision machining. Core parameters such as piston outer diameter, inner diameter, thickness, and sealing groove dimensions are completely identical to the original. The surface undergoes special wear-resistant and corrosion-resistant treatment, and paired with a dedicated sealing structure, it completely solves common problems of ordinary clutch pistons, such as sealing leakage, excessive wear, slow response, deformation, and jamming. It effectively avoids problems caused by piston failure, such as clutch slippage, shifting jerks, power transmission interruption, hydraulic oil leakage, and equipment downtime, significantly improving clutch operational stability and service life, thereby ensuring the overall transmission efficiency of the gearbox. It has become a high-performance, cost-effective choice for various scenarios, including Allison gearbox repair shops, parts suppliers, exporters, and fleet maintenance.
