Toparts YN55V00036F1 Center Joint Seal Kit for Kobelco SK135SR

Maintain the seamless operation and hydraulic precision of your excavator with the Toparts YN55V00036F1 Center Joint Seal Kit. Specifically engineered for the Kobelco SK135SR series, this premium repair kit is the professional solution for servicing the Swivel Joint Assembly (Center Joint), ensuring reliable fluid distribution between the upper structure and the undercarriage.

Essential Sealing for Kobelco Rotary Manifolds

The center joint (or swivel joint) is a critical component that allows hydraulic oil to flow to the travel motors while the excavator's cabin rotates 360 degrees. Over time, the internal seals are subjected to constant friction and high-pressure cycles, which can lead to oil mixing between circuits or external leakage. Toparts has developed the YN55V00036F1 kit to restore the "Solid Body" performance of your SK135SR, preventing power loss in the tracks and ensuring smooth machine synchronization.

Key Features and Benefits:

Direct OEM Compatibility: Precisely matched to Kobelco part number YN55V00036F1, ensuring a perfect, leak-proof fit for the SK135SR, SK135SR-1E, and SK135SRLC swivel assemblies.

Advanced Material Composition: Features high-grade PTFE (Teflon) with Bronze reinforcement and premium NBR/Viton O-rings. These materials offer exceptional wear resistance and low-friction properties, even under continuous rotation.

Eliminates Internal Bypass: Our precision-engineered seals prevent hydraulic fluid from leaking between the travel and blade ports, ensuring your tracks receive 100% of the required pressure for climbing and steering.

High-Temperature Stability: Formulated to withstand the intense heat generated by long-distance tracking and high-speed rotation, preventing the seals from hardening or cracking.

Complete Overhaul Set: This comprehensive kit includes all necessary rotary seals, dust seals, and O-rings required for a total internal service of the swivel joint.

Reduced Downtime: By utilizing Toparts' high-durability elastomers, you extend the service intervals of your rotary manifold, keeping your machine productive on the job site.
