VOLVO 14744967 Hydraulic Case Drain Filter Element SpecificationGenuine VOLVO Hydraulic Case Drain Filter Element 14744967
Product Overview: The Genuine VOLVO Hydraulic Case Drain Filter Element (P/N: 14744967 / VOE14744967), often called a Motor Oil Leakage/Drain Filter, is a critical defensive component engineered to monitor and isolate low-pressure oil leakage lines. It captures microscopic wear debris from high-torque swing and travel motors before it returns to the reservoir, serving as an early-warning sensor for hydraulic component health.
1. Core Technical Advantages
Advanced Synthetic Micro-Glass Media: Multi-layered, resin-bonded glass fibers provide elite dust-holding capacity and low flow restriction, ensuring seamless oil return.
Anti-Pressure Pleat Architecture: Rigid internal steel mesh lining prevents pleat flexing or media compaction under erratic cold-weather surges.
Thermal-Resistant HNBR Seals: Specialized endcaps and sealing rings remain resilient through high-temperature return cycles to prevent bypass.
Perforated Core Skeleton: Zinc-coated internal steel core resists varnish corrosion while maximizing flow surface area.

3. Master Application Fleet Guide
This filter is essential for the longevity of high-torque VOLVO machinery:
Mid-Range Excavators: EC140E, EC160E, EC170D, EC180E, EC220D, EC220E
Heavy Production: EC250D, EC250E, EC300D, EC300E, EC380D
Mining & Overburden: EC750D, EC750E
4. Common Field Failure Symptoms
Blown Motor/Pump Shaft Seals: Clogged filters build back-pressure in housings, causing high-pressure shaft seals to fail and leak behind drive sprockets.
Catastrophic Seizure: Blocked drain lines inhibit cooling/lubrication flow, leading to friction scuffing and motor failure.
Contaminated Hydraulic Tank: If media ruptures, metal shavings circulate back to the tank, contaminating the entire system.
Maintenance Advisory:
Replace at 1,000-hour intervals or immediately after pump/motor repair. Before servicing, lower the attachment, shut down the engine, and release tank pressure. When inspecting the old filter, cut open the media: copper or steel flakes indicate internal wear—act before total failure. Always verify machine S/N before ordering to ensure correct fit.
5. B2B Procurement Strategy
Installing a fresh case drain filter when replacing swing motors or pumps is an essential insurance policy to protect new components from debris in existing lines. We recommend grouping this filter with return, suction, and pilot filters (15035179) as a "Complete 1,000-Hour Hydraulic Overhaul Kit" to maximize B2B order value.
