Application:
31434163 is a precision-machined hydraulic valve tappet for Perkins 1004C-44T/E44T, 4.236, 4.248, 6.354 and Caterpillar C7.1 diesels. It is also used in MF 290, 390, 399, 570, 590, 670, 690 tractors, JCB 3CX/4CX back-hoe loaders and Claas combine harvesters. The tappet locates between the camshaft lobe and the push-rod, converting rotary cam motion into linear valve actuation while maintaining zero-lash throughout the 12 000 h overhaul interval.
Technical specifications:
Overall length 30 mm, head diameter 22 mm, stem diameter 12 mm, cam-contact face radius 600 mm, mass 168 g. Body is drop-forged from 20CrMo steel (0.20 % C, 1 % 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. Crown surface is phosphate-coated 5 µm to assist initial running-in, then flash-oiled for corrosion-free storage.
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.
