Caterpillar 312 Series Travel Motor Seal Kit

This travel motor seal kit is engineered to reseal the hydraulic final drive motor on Caterpillar 312 series excavators. The kit contains a complete set of dynamic and static seals including piston seals, shaft seals, O-rings, and backup rings manufactured to OEM dimensional tolerances. Materials are selected for compatibility with mineral-based and biodegradable hydraulic fluids operating at pressures up to 35 MPa. Designed for direct installation during final drive overhaul or motor replacement to eliminate external leakage and restore internal hydraulic efficiency. Compatible with multiple OEM part number configurations across 312B, 312C, and 312D model generations. Seal profiles and elastomer compounds meet Caterpillar material specifications for wear resistance and thermal stability in heavy-duty track drive applications. Kit contents vary by specific motor part number grouping; verify motor nameplate part number prior to order.
