Application:
Perkins 2306, 2506, and 2806 series six-cylinder diesel engines (12.5-18.0 L displacement), specifically models 2306TAG, 2506A-E15TAG, 2506C-E15TAG, 2806A-E18TAG, and 2806C-E16TAG. This valve collet secures the intake and exhaust valves (CH11021 and CH11022) to the valve spring retainers in high-boost turbocharged applications where valve train stability is critical. Each six-cylinder engine requires 48 collets (8 per cylinder: 2 collets per valve × 4 valves per cylinder). Commonly found in FG Wilson 500-800 kVA generator sets, large agricultural tractors, mining equipment, and heavy-duty construction machinery operating in continuous-duty environments.
Technical specifications:
Type: Split wedge-shaped valve keeper/collet
Material composition: High-strength chromium-molybdenum alloy steel (Cr-Mo)
Taper angle: 7° (matches standard Perkins valve stem groove geometry)
Groove engagement: Fits 1.5-1.7 mm wide valve stem groove
Quantity per engine: 48 pieces for 6-cylinder applications
Individual weight: Approximately 2.5 grams (0.088 oz)
Packaged weight: 0.49 lbs (220 grams) for 50-piece pack
Dimensions: Tapered wedge profile, approximately 10 mm length × 6 mm width at base
Hardness: 45-50 HRC after heat treatment
Surface finish: Precision machined to Ra 0.8 µm for secure locking
Material & performance features:
Manufactured from vacuum-degassed Cr-Mo alloy steel providing 800 MPa tensile strength and superior fatigue resistance essential for high-frequency valve oscillation at engine speeds up to 2,200 rpm. Each collet undergoes precision forging and heat treatment to achieve optimal hardness balance: sufficiently hard to resist deformation under 1,100 N valve spring load, yet ductile enough to prevent brittle fracture during installation.
