Restore the precision and tilting power of your earthmoving equipment with the Toparts 175-63-05140 Hydraulic Cylinder Seal Kit. Specifically engineered for the Blade Tilt Cylinder of the Komatsu D155A-1 Crawler Dozer, this premium repair kit is the professional solution for eliminating hydraulic leaks and ensuring your blade maintains the exact angles required for heavy-duty grading and dozing.

Engineered for Komatsu D155A-1 Performance

The Komatsu D155A-1 is a legendary workhorse in the mining and construction industries. Its blade tilt cylinder is subject to immense stress, high-pressure spikes, and constant exposure to abrasive dust and debris. Toparts has developed the 175-63-05140 kit using advanced elastomers that meet or exceed OEM standards, providing a reliable seal that can withstand the punishing environment of a dozer's front-end attachments.

Key Features and Benefits:

Direct OEM Replacement: Fully compatible with Komatsu part number 175-63-05140, ensuring a precision, leak-proof fit for the D155A-1 blade tilt cylinder without the need for modifications.

Superior Material Composition: Manufactured from high-tensile Polyurethane (PU) for the rod and piston seals, combined with specialized NBR (Nitrile) O-rings. These materials are chosen for their excellent resistance to abrasion, heat, and hydraulic fluid degradation.

Eliminates Cylinder Drift: Our high-performance seals ensure maximum pressure retention, preventing the blade from "drifting" or losing its position during heavy pushing or precision grading.

Superior Contamination Protection: Includes a heavy-duty wiper seal designed to scrape away mud, grit, and rocks from the cylinder rod, protecting the internal components from scoring and premature wear.

Complete Repair Solution: This comprehensive kit includes all essential sealing elements—rod seals, piston seals, back-up rings, and O-rings—required for a professional-grade cylinder overhaul.

Built for Longevity: Engineered to maintain elasticity and sealing integrity even in extreme temperatures and high-vibration environments, reducing your long-term maintenance costs.
