Heavy-Duty 11709817 / 11107525 Hydraulic Steering Cylinder Seal Kit for Volvo L90E, L90F, L110E & L120E Wheel Loaders

Product Overview

Restore crisp articulation response and sharp ground handling with our targeted Hydraulic Steering Cylinder Repair Kit (Part Numbers: 11709817 / VOE11709817 / 11107525).

Unlike heavy front tilt cylinders that endure sudden breakout shocks, articulated steering cylinders experience continuous micro-adjustments, high thermal cycling, and constant lateral pressure shifts. Engineered specifically for Volvo L90E, L90F, L110E, and L120E medium-wheel loaders (fits 45mm rod / 90mm cylinder bore specifications), this kit eliminates hydraulic fluid bypass, stops steering wheel “sponginess,” and prevents dangerous machine wander during tight-quarter material loading.

Key Technical & Operational Differences

• Optimized Dynamic Hydro-Sealing

  Features low-friction, high-resilience Polyurethane (PU) rod seals coupled with NBR energy rings, formulated to maintain continuous seal-lip contact during rapid, constant steering angle adjustments without generating excess thermal friction.

• Zero-Drift Articulation Stability

  Precision-profiled piston seals eliminate internal bypass between cylinder chambers, keeping the machine’s central pivot lock-tight when carrying full buckets across uneven quarry or aggregate job sites.

• Dual-Lip Contamination Guard

  Equipped with a aggressive double-lip dust wiper that scrapes away ultra-fine rock dust, wet mud, and abrasive dirt, protecting the chrome rod from scoring and keeping clean fluid within the central steering circuit.

Steering System Maintenance & Service Advice

🔧 Symmetrical Replacement Strategy: Wheel loader steering systems utilize two identical cylinders operating in tandem. When one side begins to weep hydraulic oil, the opposite cylinder’s seals have endured the exact same number of pressure duty cycles. Replacing both left and right steering cylinder seals during a single service window prevents hydraulic pressure imbalance and eliminates repeat downtime.

Fitment Verification: Please verify your machine’s pin-to-pin cylinder setup and serial number against Volvo OEM catalog specifications prior to installation.
