OEM Final Drive Travel Motor for Bobcat E25 E26 E27 E27Z | Part No. 7190517

1. Product Overview
The 7190517 is a precision-engineered integrated propulsion unit featuring a two-speed axial piston motor and a multi-stage planetary reduction gearbox. As the primary drive component for the Bobcat 2.5-ton to 3-ton "Next Generation" series, it is designed to provide smooth tracking and maximum tractive effort. With 13 years of specialized experience in hydraulic systems, we ensure these drives are calibrated to handle the increased flow and pressure of modern Bobcat machines, ensuring consistent speed and powerful climbing performance.

3. Technical Specifications & Performance
Motor Type: Variable displacement axial piston motor with integrated 2-speed travel (High/Low) switching.

Reduction System: High-torque planetary gears manufactured from induction-hardened alloy steel for superior fatigue resistance.

Max Pressure: Designed to meet the factory relief settings (typically 210–250 bar) to ensure maximum breakout and tracking force.

Sealing: Equipped with premium "Duo-Cone" mechanical floating seals to protect the gear system from mud, standing water, and abrasive grit.

Braking: Integrated spring-applied, hydraulic-release wet disc parking brake for safe holding on steep inclines.

4. Why Partner With a 13-Year Industry Expert?
Hydraulic Synchronization: We understand the exact flow requirements for the Bobcat E-series. Our motors are calibrated to ensure your machine tracks perfectly straight, eliminating the "drift" common with lower-quality aftermarket drives.

Rigorous Performance Testing: Every unit undergoes a 100% bench test. We verify volumetric efficiency, brake holding torque, and smooth 2-speed shifting before the unit is shipped.

OEM-Grade Reliability: We provide Original New units that use the same internal components as the factory-installed drive, ensuring a zero-hour service life and perfect fitment.

Global Rapid Logistics: Units are secured in reinforced, shock-proof export wooden crates. Express delivery via DHL, FedEx, or UPS typically arrives in 3 to 7 business days.

5. Critical Installation & Maintenance Protocol
Gear Oil Commissioning: Final drives are shipped without gear oil for safety. You must fill the planetary gearbox with the correct volume of SAE 80W-90 gear oil before use.

Case Drain Verification: Ensure the case drain line is clear and connected to the center port. Obstructions in this line will cause the motor shaft seal to blow out immediately.

Hydraulic System Flushing: If the previous motor failed due to internal breakage, you must flush the hydraulic tank and lines. Residual metal shavings are the primary cause of premature failure in replacement motors.

Air Bleeding: After installation, lift the track off the ground and run the motor at low speed in both directions for several minutes to purge air from the hydraulic lines.

6. Ordering & Professional Support
Fitment Verification: To ensure 100% accuracy, please provide your Machine Serial Number (e.g., Prefix B3T or B2G) and the number of sprocket mounting holes (standard is 9 or 12).
