Application:
3174A031 is the outer valve spring for 4-cylinder Perkins 1104D-44 / 1104D-44TA, 1104C-44T and Caterpillar C4.4 industrial diesels (4.4 L). It is installed around both inlet and exhaust valves in engines that power JCB 3CX/4CX back-hoe loaders, Case Maxxum MX tractors, 45–70 kVA “Vista A” generator sets and MF 5400-series farm tractors, maintaining correct valve motion up to 3 000 min⁻¹ while meeting EU Stage IIIA / EPA Tier 4-final emission limits.
Technical specifications:
Free length 50 mm, outer diameter 31 mm, wire diameter 3.5 mm, 6.5 active coils, solid length 30 mm. Material is chrome-vanadium spring steel (50CrV4) oil-quenched and tempered to 47 HRC, then shot-peened to 0.25 mm A-intensity to raise fatigue life to 1 × 10⁷ cycles.
Material & performance features:
The 50CrV4 alloy (0.5 % C, 1 % Cr, 0.15 % V) offers 1 600 MPa tensile strength and 8 % elongation, resisting surge-set when exhaust temperature reaches 700 °C. Controlled shot-peening induces 400 MPa compressive stress on the outer surface, delaying fatigue crack initiation and extending service life to 12 000 h.
