WESPC Valve Cotter 3142W005 for Perkins 1103 1104 Diesel Engine - 24mm Length, 2.0mm Groove Width

WESPC Valve Cotter 3142W005 is a precision-engineered component designed for Perkins 1103 and 1104 diesel engines, providing reliable valve retention in demanding industrial applications.

This hardened-steel split cotter securely locks inlet and exhaust valves in 3- and 4-cylinder Perkins 1103/1104 diesel engines (3.3-4.4L displacement). It is engineered for heavy-duty applications including:

• JCB 3CX back-hoes
• MF 1700 tractors
• 45 kVA "Vista A" generator sets
• Caterpillar C6.6 and 1106C-E60TAG4 engines

The cotter is designed to withstand 30g valve-train acceleration at 3,000 min⁻¹ while maintaining structural integrity, ensuring reliable performance for up to 12,000 hours before overhaul.

Manufactured from 20CrMnTi alloy steel (0.20% C, 1.0% Cr, 0.8% Mn, 0.04% Ti) with exceptional mechanical properties:

• Tensile strength: 1,100 MPa
• Elongation: 12%
• Impact fatigue resistance for 9mm cam lifts
• Controlled taper ensures uniform radial load distribution
• Groove wear limited to <0.02 mm after 6,000 hours
• Phosphate coating retains oil during cold starts, reducing initial scuffing by 30%
• 8° angle maintains self-locking capability up to 550N spring preload
