High-pressure PC138US-8 travel motor seal kit ensuring reliable sealing and long-term final drive durability.
OEM-equivalent replacement for TZ467B9000-00 / GMY23VL-BB-48
Designed for Komatsu PC138US-8 travel motor / final drive
High-pressure-resistant seals suitable for heavy-duty excavator travel systems
Resists heat, contamination, abrasion, and gear oil pressure
Ideal for travel motor rebuild shops, fleets, and aftermarket distributors
The YNF17721 TZ467B9000-00 travel motor seal kit is engineered for the Komatsu PC138US-8 final drive (GMY23VL-BB-48). As a critical sealing component inside the travel motor, this seal kit prevents gear oil leakage, protects internal bearings, and maintains proper hydraulic pressure during travel operations. Final drives operate under extremely harsh conditions—heavy loads, constant vibration, high temperature, and contaminated environments—making high-quality seals essential for long service life.
Made from premium materials such as NBR, HNBR, PTFE, and high-strength wear-resistant polymers, this seal kit restores sealing performance and reduces the risk of motor overheating, loss of torque, or gear damage. The kit includes mechanical face seals, O-rings, floating seals, shaft seals, and other core sealing elements needed for a full rebuild.
YNF Machinery supplies stable quality and competitive pricing, making this kit suitable for professional repair workshops, equipment fleets, and global excavator parts distributors.
