The Ultimate Hydraulic Filtration Solution for Your Bobcat E85: A Review of the 6668819 6598903 Hydraulic Oil Filter
When operating high-performance machinery like the Bobcat E85 excavator, the integrity of your hydraulic system is non-negotiable. The hydraulic system is the heartbeat of your work machine, providing the force necessary for digging, lifting, and grading. If the oil is not pristine, the machine suffers. That is why choosing the right filtration component is critical. The 6668819 6598903 Hydraulic Oil Filter represents a commitment to Zero Defects and a Perfect Finish, ensuring that your equipment remains in peak operating condition.
For heavy equipment owners, downtime is the enemy. Whether you are managing a fleet of skid steers or operating a single powerful E85 excavator, clean hydraulic oil is the key to longevity. This filter is engineered to meet or exceed OEM standards, providing a level of filtration that keeps abrasive contaminants away from your sensitive hydraulic valves and pump components.
Unrivaled Engineering: A Focus on Zero Defects
The philosophy of “Zero Defects” in manufacturing is essential when dealing with pressure-sensitive equipment. A minor imperfection in a filter’s bypass valve or media pleating can lead to catastrophic pump failure over time. The 6668819 6598903 filter is constructed with high-grade materials designed to withstand the high-pressure surges characteristic of the Bobcat E85 and other models in the series.
By utilizing advanced filtration media, this unit captures sub-micron particles that often slip through lower-quality alternatives. When you prioritize a perfect finish in your maintenance routine, you are essentially investing in the resale value and operational reliability of your machine.

Pros and Cons Breakdown
| Pros | Cons |
|---|---|
| Exceptional filtration efficiency prevents premature pump wear. | Must ensure proper priming to avoid air traps. |
| Rugged construction, ideal for demanding E85 excavator workloads. | Generic packaging in some shipments compared to dealer-branded boxes. |
| Perfect fitment across a massive range of Bobcat equipment. | Requires standard filter wrench for removal/installation. |
Performance and Reliability
In practice, the difference between an average filter and this high-performance unit is immediate. Operators report smoother joystick response in the E85 excavator, which is a direct result of clean hydraulic fluid reaching the pilot valves. With “Zero Defects” manufacturing, the internal bypass valve opens reliably under cold-start conditions, protecting your hydraulic system from high pressure during the initial warm-up phase.
For those managing a fleet, stocking this specific filter is a strategic decision. Because it fits such a wide array of Bobcat machines—from the older 743 models to the modern E85—it simplifies inventory management. You are not just buying a filter; you are ensuring that your entire fleet operates at the same high standard of hydraulic cleanliness.
Frequently Asked Questions (FAQ)
Q: Is this filter compatible with my Bobcat E85?
A: Yes, this filter is specifically listed as compatible with the E85 and a large number of other Bobcat excavators, skid steers, and utility machines.
Q: How often should I change the hydraulic filter on my excavator?
A: While it depends on your specific duty cycle, it is generally recommended to follow the OEM intervals stated in your Bobcat service manual, typically every 500 to 1,000 hours, or sooner if you operate in extremely dusty environments.
Q: Does the “Zero Defects” claim mean this filter is better than the original part?
A: It means the manufacturing process focuses on eliminating the variability and potential manufacturing flaws found in cheaper aftermarket filters, resulting in a product that matches or exceeds OEM performance standards.
Q: Can I use this for both the hydraulic system and the hydrostatic transmission?
A: This filter is designed for hydraulic fluid systems. Please refer to your machine’s service manual to confirm if the same part number is specified for your transmission, as requirements can vary by model.
Investing in the quality of your maintenance supplies is the hallmark of a professional operator. With its robust construction and commitment to perfection, the 6668819 6598903 Hydraulic Oil Filter is an essential component for keeping your Bobcat equipment performing at its best.
