KYB MAG-18V-350F-2 Final Drive for Bobcat E32 E34 E35 E37 | OEM Part No. 6698127 7009157

1. Product Overview
The KYB MAG-18V-350F-2 is an integrated hydraulic transmission comprising a high-efficiency axial piston motor and a robust planetary reduction gearbox. Specifically engineered for Bobcat’s E-series, this unit is designed to handle the increased hydraulic pressures and flow rates of modern "Next Gen" machines. As the original equipment manufacturer (OEM) for Bobcat, KYB ensures this drive provides the precise torque required for synchronized tracking, effortless counter-rotation, and maximum climbing power on steep grades.

2. Comprehensive OEM Part Number Compatibility
This assembly is a direct "bolt-on" replacement for the following Bobcat and KYB part numbers:

Bobcat Part Numbers: 6698127, 7009157.
Manufacturer Model: KYB MAG-18V-350F-2 (also cross-compatible with select MAG-18V-230 series).

Machine Fitment:

E32 Series: E32, E32i (Standard and Long Arm).

E34 Series: E34 (Next Generation).

E35 Series: E35, E35i, E35Z (Zero Tail Swing / Next Gen).

E37 Series: E37.

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

Gearbox Architecture: Multi-stage planetary reduction gears manufactured from high-strength, induction-hardened alloy steel.

Max Working Pressure: Rated up to 350 bar (35 MPa) to maintain original factory tractive effort and breakout force.

Sealing: Equipped with premium mechanical "floating seals" (Duo-Cone) to protect internal gears from mud, water, and grit.

Integrated Valve Block: Includes built-in relief valves and counterbalance valves to prevent over-speeding on slopes and ensure smooth braking.

4. Why Partner With a 13-Year Industry Expert?
KYB OEM Authenticity: We supply genuine KYB units, ensuring the internal piston sets and valve plates match the original factory hydraulic curve. This prevents the "pulling" or "drifting" common with low-quality aftermarket drives.

Rigorous Bench Testing: Every unit undergoes a 100% load test on a hydraulic test bench to verify volumetric efficiency, brake holding torque, and smooth 2-speed shifting.

Factory-Direct Value: Leverage our established supply chain to access Original New units at competitive wholesale prices, avoiding the 40–60% markups found at local dealerships.

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

5. Critical Installation & Maintenance Protocol
Gear Oil Filling: Final drives are shipped without gear oil for transit safety. You must fill the planetary gearbox with SAE 80W-90 gear oil to the correct level before operation.

Case Drain Connection: Verify that the case drain line is clear and connected to the center port. High backpressure in the motor case is the leading cause of shaft seal failure and internal motor damage.

Hydraulic System Cleanliness: 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 new units.

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

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