4. FAQ

Q: Which construction excavators and matched engines does this 4N-0865 gasket fit, and where is it installed?
A: This gasket set fits medium and large construction excavators equipped with C9 series industrial engines. It is mounted on the flange joint of engine fuel supply pump, responsible for sealing fuel liquid at the pump connection, and contains all matched small rubber sealing rings needed for fuel pump disassembly maintenance.

Q: What practical advantages does fiber composite with metal strip bring to fuel pump sealing?
A: Excavators work outdoors with frequent bumpy vibration and alternating cold and hot temperatures. Non-asbestos fiber has stable compression recovery and will not produce permanent deformation after long bolt clamping. The embedded thin metal strip prevents the gasket from cracking during disassembly. The outer oil-proof rubber coating blocks fuel penetration and swelling, and matched NBR sealing rings handle small auxiliary holes to maintain stable sealing effect for long-time construction work.

Q: What color and structural features do these gaskets have?
A: The main special-shaped double-hole flat gasket is light gray, with four precise positioning holes and uniform thickness. Silver thin metal strips are wrapped around the outer sealing edge for reinforcement. All supporting NBR O-rings are solid black with smooth round surfaces, and different sizes can be quickly distinguished during on-site assembly without mixing parts.
