Product Description
Heavy-Duty 7135559 Lift Cylinder Service Repair Kit for Bobcat Skid Steer Loaders (Fits 7117667)
Restore dependable lifting performance and eliminate hydraulic sagging in your loader frame with Toparts' premium 7135559 lift cylinder seal kit. Specifically precision-engineered for the 7117667 hydraulic lift cylinder utilized across Bobcat compact skid steers, this overhaul service kit is built to survive the relentless cycle frequencies, extreme pressure shocks, and harsh environmental debris common in agricultural, landscaping, and construction applications.
The Toparts Engineering Difference: Engineered for Gritty, High-Impact Work
Skid steer lift cylinders operate in the absolute worst conditions. Positioned directly alongside the loader frame, they are continuously bombarded by flying gravel, concrete dust, corrosive animal waste, and thick mud. Standard aftermarket seals quickly suffer from lip hardening or micro-tearing under these conditions, causing fluid bypass, pressure loss, and dangerous lift arm unbalance. At Toparts, we manufacture our Bobcat-compatible kits with explicit material upgrades:
Premium P6000 Polyurethane Matrix: Our primary rod and piston seals are molded from proprietary, industrial-grade P6000 PU. This material provides 40% higher tensile strength and superior extrusion resistance under intense hydraulic spikes compared to standard TPU, keeping the sealing lip razor-sharp and firmly active.
Aggressive Environmental Dust Scraper: Features an engineered double-lip scraper system that vigorously wipes away fine quartz dust, mud, and water films from the extending rod, protecting the internal sealing elements and cylinder wall from score marks.
Zero-Drift Heavy Duty Buffer Ring: The integrated step seals and buffer rings utilize precision-filled PTFE compounds backed by premium NBR energizers. This design absorbs sudden shock loads when digging into heavy piles, preventing localized thermal buildup and maintaining strict holding power.
High Elastic Memory Static Seals: All static O-rings and backup rings are formulated to resist compression set and continuous high oil temperatures up to 120°C, ensuring tight static sealing across the cylinder head connection.
