Oil Filter Element – Part No. 40056007

Replacement oil filter element supplied against part number 40056007. Public cross-reference data place this number in diesel-locomotive engine oil / fuel-lube service as well as generic hydraulic replacement programs; final media, micron rating, and dimensions must be matched to the existing cartridge and filter housing before ordering.

Typical Applications

• Diesel locomotive engine oil filtration (four-stroke diesel engines, railway traction, marine diesel auxiliaries)

• Fuel/lube general filtration where the same element number is listed as a replacement cartridge

• Industrial hydraulic or lube circuits only after dimensional and β-ratio verification

Key Features

• Pleated cartridge construction for high dirt-holding capacity

• Microglass or cellulose media options; microglass gives stable β-ratio and higher efficiency than cellulose

• Configurable micron grade, end caps, center tube, seals, and overall envelope

• Reusable metal components available; media cartridge is normally disposable

• Suitable for continuous engine-lube cleanup and offline/kidney-loop service

Technical Data (verified vs configurable)

Micron Selection by Duty

• 1–5 µm absolute – servo/proportional lube systems, precision turbine/control oil

• 10–25 µm – general diesel engine oil, pressure/return hydraulic lines

• 25–100 µm – suction strainers, coarse lube/gear-oil guard

• Nominal vs absolute – nominal may capture only 50–90% at rated size; absolute is verified by multipass β. Always specify absolute β when protecting tight-clearance components.

Fluid Compatibility

• Mineral diesel engine oil, hydraulic oil (HH/HL/HM/HV) – NBR seals

• Synthetic lube/PAO – confirm media binder; FKM seals recommended

• Water-glycol (HFC) or phosphate-ester (HFDR) – special media and FKM required; not default for 40056007

• Fuel/lube dual service – confirm with supplier; some 40056007 listings cover fuel/lube replacement only

Cross-Reference Rules

A valid replacement must match five items: outer diameter, inner diameter, overall length, end-cap/thread pattern, and filtration efficiency (β at target micron). Collapse/burst pressure must match circuit position—low-pressure return elements must not be fitted in high-pressure lines.

Installation & Service

1. Isolate equipment; relieve pressure to zero.

2. Remove old element; inspect media for metal particles, sludge, or water emulsification.

3. Clean housing, bypass valve, and seal grooves.

4. Fit new element with correct flow direction; renew all O-rings/gaskets.

5. Set bypass/change-out differential per OEM; for hydraulics many programs replace at 25 PSID or by clogging indicator.

6. Return to service; check for leaks and monitor ΔP.

7. Replace per oil-analysis ISO 4406/NAS trend,压差 indicator, or scheduled interval; do not extend indefinitely after component failure.

Ordering Information

State “40056007” plus:

• Equipment/model and circuit (locomotive diesel lube / hydraulic / fuel-lube / gear oil)

• Old element OD × ID × length, end-cap drawing, thread or flange

• Required micron and β (e.g., 10 µm absolute β₁₀ ≥ 200, or 13 µm average 90% as listed)

• Media (microglass/cellulose/mesh), collapse pressure, flow rate

• Fluid type, operating temperature, pressure, seal material (NBR/FKM)

Provide a photo or used-element sample for cross-check. Custom dimensions are available; dimensional match alone is insufficient—performance match is mandatory.
