Application:
T400755 is an intake-valve seat ring designed for Perkins
1506A/E88TAG and 1104/1004 family 4- and 6-cylinder diesels (4.4 L
& 8.8 L) that power 60 Hz prime generators, combine harvesters, MF
6400-series tractors and marine auxiliary sets rated 150–250 kW. It
is pressed into the cylinder-head inlet port to give a 45 °, 0.02
mm-concentric seal surface for valves with 38 mm head diameter,
ensuring volumetric efficiency stays above 92 % at 2 800 min⁻¹
while meeting EU Stage IIIA smoke limits.
Technical specifications:
OD 46.0 mm, ID 38.5 mm, thickness 7.0 mm, seat angle 45 °,
interference fit 0.06–0.10 mm in aluminium head, depth in pocket
7.5 mm. Material is low-carbon (0.15 %) steel billet that is
copper-infiltrated and sintered to 7.2 g cm⁻³ density, giving 350
HB hardness and thermal conductivity 45 W m⁻¹ K⁻¹ for rapid heat
rejection.
Material & performance features:
The copper-infiltrated matrix resists valve micro-welding and
transfers heat away from the 21-4N stainless valve head, keeping
seat temperature below 220 °C even when inlet air reaches 60 °C.
Controlled 0.25 µm Ra surface finish beds in within 50 h,
maintaining blow-by <1 % for the engine’s full life.
