                                                                                      •    - Dirt and Dust Ingress Protection: Features a secondary "dust lip" to prevent the fine, abrasive particulates common in mining environments from reaching the primary sealing surface.

                                                                                      •    - Direct OEM Fit: Manufactured to the exact 703-15-95011 dimensions, ensuring a leak-free interface with Komatsu’s precision-machined housings.

This seal is a critical component for Komatsu’s largest crawler excavators:

Q&A Section

Q1: Is the 703-15-95011 seal used in the hydraulic cylinders?

A: No. This part number is typically associated with the power train or hydraulic pump drive (PTO). Cylinder seal kits for these machines involve much larger diameter components and multiple-piece sets.

Q2: What is the risk of using a low-quality alternative for this seal?

A: In mining machines like the PC2000-8, a seal failure can lead to the rapid loss of dozens of gallons of expensive hydraulic oil or, worse, the "running dry" of a transmission or pump drive, which can cost tens of thousands of dollars to repair.

Q3: Does this seal require a special installation tool?

A: Due to the precision required in mining equipment, it is highly recommended to use a seal driver that applies even pressure to the outer diameter. This prevents the seal from "cocking" in the bore, which is a common cause of immediate leaks upon restart.
