Rebuild Parts for Caterpillar

Caterpillar heavy machinery has high requirements for overall structural strength and hydraulic stability, and professional overhaul accessories are the key to ensuring long-term stable operation of old equipment. Yantai Dayun Machinery Parts provides high-precision, wear-resistant rebuild parts for Caterpillar, specially designed for Caterpillar excavators and engineering machinery overhaul and component replacement.

Our product range focuses on core reconstruction needs: engine internal overhaul components, hydraulic system repair assemblies, cylinder sealing and wearing parts, swing & travel device repair kits, and high-load chassis reconstruction accessories. All Caterpillar rebuild parts are manufactured with reference to original equipment design standards, with strong bearing capacity and high temperature resistance, adapting to long-hour continuous operation. Like the pump 270-3951 2703951 for CS74, the pump 423-2543 4232543 for M318, the pump 333-7827 3337827 for D9T, 369-9655 3699655 for 390D and so on.

Different from ordinary daily maintenance parts, overhaul components need higher overall matching and coordination. Our technical team will sort out the differences between old and new model parameters, mark applicable machine types in detail, and help customers avoid purchasing errors in large-scale reconstruction projects.
