OEM Oil Filler Cover Assembly 1004026001 precision‑manufactured for the Shacman X5000 diesel engine. This essential 1004026001 component seals the oil fill port, preventing contaminants from entering while allowing convenient engine oil replenishment.
Molded from high‑temperature resistant engineering polymer with an integrated sealing element, the Oil Filler Cover Assembly 1004026001 provides a secure bayonet‑style closure that resists loosening from engine vibration.
Replacing a damaged or missing filler cover with the genuine 1004026001 unit protects your engine from dust, moisture, and the oil loss that results from an improperly sealed fill port.

The 1004026001 oil filler cover assembly is the primary access point for adding engine oil to the Shacman X5000 powerplant. It must provide a reliable seal under both vacuum and pressure conditions within the crankcase.
A properly functioning Oil Filler Cover Assembly 1004026001 prevents unfiltered air and abrasive dust from entering the engine during operation. It also contains oil splash within the valve train compartment during high‑RPM operation.
The bayonet locking mechanism allows tool‑free access for routine oil level checks and top‑ups, while providing positive retention that cannot vibrate loose during long highway journeys.
The 1004026001 cover is injection‑molded from PA66‑GF30, a glass‑fiber reinforced nylon that offers exceptional dimensional stability across a wide temperature range and resistance to hot engine oil.
This material does not become brittle with age or exposure to under‑hood chemicals. The glass fiber reinforcement provides the mechanical strength necessary to maintain its locking geometry over thousands of service cycles.
The integrated fluorosilicone O‑ring in the 1004026001 assembly provides a long‑life seal that resists compression set at elevated temperatures. It remains elastic and effective throughout the engine’s oil change intervals.
Installation requires only aligning the bayonet lugs with the filler neck slots and rotating the cover clockwise until it seats firmly. An audible click confirms proper engagement of the Oil Filler Cover Assembly 1004026001.
Each 1004026001 cover undergoes a thermal cycling test from -40°C to +150°C for 500 cycles. Post‑test inspection verifies that the locking mechanism remains functional and the O‑ring maintains its sealing integrity.
Vibration testing simulates 100,000 kilometers of engine operation to confirm that the bayonet lock does not back off under resonance conditions. The cover must remain fully seated throughout the entire test duration.
Oil residue around the filler neck or a persistent oil burning smell after engine warm‑up indicates that the 1004026001 cover seal has degraded. This allows oil vapor to escape and condense on surrounding surfaces.
A cracked or cross‑threaded cover may not tighten fully, leading to crankcase ventilation system malfunctions and potential engine oil starvation if enough oil escapes during operation.
During routine service, the O‑ring should be inspected for hardening or cracking. If the seal shows signs of deterioration, the entire Oil Filler Cover Assembly 1004026001 should be replaced.
The 1004026001 cover is specifically designed for the Shacman X5000 oil filler neck dimensions and locking interface. It is not interchangeable with generic aftermarket caps that lack the correct bayonet profile.
Fleet maintenance programs benefit from standardizing on the genuine 1004026001 part, ensuring that every vehicle has a properly sealing oil filler cover that prevents contamination entry.
Aftermarket filler covers often lack the precise sealing geometry and material quality of the original component. We supply only the authentic Shacman X5000 Oil Filler Cover Assembly 1004026001.
