Application:
198217470 is the outer valve spring for 4-cylinder Perkins 403C-15,
403D-15, 403D-15T, 404C-22, 404C-22T and 404D-22TA diesels (2.2 L).
It is installed around both inlet and exhaust valves in engines
that power Terex TLB back-hoe loaders, Case SR/SV skid-steers, 45
kVA “Vista A” generator sets and mini-excavators, maintaining
correct valve motion at speeds up to 3 000 min⁻¹.
Technical specifications:
Free length 48 mm, outer diameter 29 mm, wire diameter 3.2 mm, 6
active coils, solid length 28 mm. Material is chrome-vanadium
spring steel (50CrV4) oil-quenched and tempered to 47 HRC,
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.
