2.Material Composition
-
Main Materials:
-
Fluorocarbon Rubber (FKM/Viton): Resistant to high temperatures (-20°C to 250°C), oil, and chemicals, ensuring long-term sealing performance.
-
Metal Skeleton: Typically stainless steel or zinc-plated steel for structural strength and stability.
-
-
Auxiliary Coating: Some models may feature a PTFE (Teflon) coating to reduce friction and extend valve guide life.
OEM Standards: Complies with BMW’s original material specifications and is compatible with BMW engine oils (e.g., BMW LL series).
3.Production Process
-
Precision Injection Molding: FKM is molded under high pressure and temperature, bonded to the metal skeleton.
-
Post-Curing: Eliminates internal stress, enhancing elasticity and durability.
-
Laser Inspection: 100% dimensional check of the sealing lip (tolerance ±0.05mm) for proper valve stem fit.
-
Surface Treatment: Anti-corrosion coating on metal parts; rubber surfaces are burr-free.
4.Installation Method
Replacement Steps (Professional Tools Required):
-
Disassembly:
-
Remove the valve cover, camshaft, and use a valve spring compressor to release the valve locks/springs.
-
-
Removing Old Seal:
-
Extract the old valve stem seal using a specialized puller or needle-nose pliers; clean the valve guide seat.
-
-
Installing New Seal:
-
Lightly lubricate the new seal’s inner lip with engine oil, then press it in vertically using an installation sleeve (e.g., BMW tool #113450) to avoid misalignment.
-
-
Reassembly:
-
Reinstall valve springs and locks, then torque camshaft bolts to spec (e.g., N52 engine: 20Nm + 90° turn).
