WESPC Valve Tappet 120116160 For Perkins 403C-15 403C-17 404C-22 404C-22T

Application:

Valve Tappet 120116160 is machined for the 4-cylinder 403C-15, 403C-17, 404C-22 and 404C-22T families of Perkins diesels (2.2–2.8 L) that power compact agricultural tractors such as the Massey Ferguson 1700 E-series, Gehl SL4610 / SL4615 skid-steers, 50 Hz prime generators and small industrial sweepers. These engines run up to 2 800 min⁻¹, so the tappet is hardened to keep cam-follower contact stress below 1 700 MPa while maintaining a maximum 0.05 mm concave wear crown that preserves correct valve lash for the full 6 000 h overhaul interval.

Technical specifications:

overall length 30.0 mm, head diameter 22.0 mm, stem diameter 12.0 mm, cam-contact face radius 600 mm, mass 36 g. The body is drop-forged from 20CrMo steel (0.20 % C, 1.0 % Cr, 0.20 % Mo), through-hardened to 58 HRC at the crown and 45 HRC on the stem to resist brinelling under 12 kN spring load.

Material & performance features:

the 20CrMo alloy offers 900 MPa tensile strength and 12 % elongation, resisting impact fatigue when the cam lifts 9 mm at 30 g acceleration. Induction-hardened crown depth is 2.0 mm, delaying pitting beyond 8 000 h even when sulphated ash fuel is used. Phosphate layer retains oil during cold starts, cutting initial wear by 30 %, while the controlled 600 mm crown radius keeps Hertzian stress 15 % lower than flat followers, extending camshaft life accordingly.
