In Russia's logging regions and Siberian taiga, excavators operate in deep snow, mud, and permafrost year-round. In these environments, travel motors endure drag torques up to 2.5 times higher than standard surface conditions. If your CAT 320B or 330B is tracking unevenly or stalling on inclines, it’s a clear signal of internal pressure bypass within the motor's rotary group.

Repairing a travel motor is about more than just a seal kit; it’s about restoring the torque output. During frequent starts, stops, and counter-rotations, massive backpressure is generated. If replacement parts lack precise OEM geometric tolerances, high-pressure oil simply escapes through the gaps. Our 320B travel components are engineered for ratings up to 200m/min, ensuring that every piston facilitates a 100% pressure-to-torque conversion within the cylinder bore.

Crucially, we integrate the Ball Bearing Spring Guide into these kits. Specifically for rugged Russian terrains, this mechanism prevents the "yaw" or tilting of the return stroke under uneven loading. For Russian fleet managers, this means that even when the machine is buried in deep snow, the motor provides the necessary low-speed, high-torque output to pull the machine through without risking internal component shattering from sudden overloads.
