WESPC Valve Seat 3314A061 For Perkins 1006-60T T6.601 CCW6.601 Family

Application:

Valve seat 3314A061 is the intake seat specified for the six-cylinder Perkins 1006-60T, T6.601 and CCW6.601 family (6.0 L) used in mid-range agricultural tractors such as the Massey Ferguson 3125/3140, combine harvesters including the MF 30, 36 and 40 series, 60-100 kVA generator sets, and industrial sweepers, forklifts and irrigation pumps. The same seat is also fitted to the later 1106D-E60TA electronic engines that power tele-handlers, trenchers and mobile compressors, making it a high-volume service item across farms, rental fleets and construction yards worldwide.

Technical specifications:

The seat is a press-in ring 45.6 mm outside diameter, 38.1 mm inside diameter and 8.9 mm overall height, machined with a 30° conical face that mates with the intake valve head. The outside diameter is precision-ground to a 0.04 mm interference fit to guarantee positive retention in the cast-iron cylinder head, while the 2.2 mm wide seat contact band seals reliably at boost pressures up to 1.6 bar and inlet air temperatures of 220 °C.

Material & performance features:

The seat is manufactured from a low-carbon Cr-Mo-V sintered steel (Fe-2Cr-1.5Mo-0.8C) that is oil-quenched after sintering to reach a core hardness of 88 HRB, then double-tempered to relieve internal stress. The working face is high-frequency induction-hardened to 50 HRC to a depth of 1.0 mm, giving a wear index better than 800 hours in continuous 2800 rpm field tests. A manganese phosphate conversion coating (2–3 µm) is applied to the outer diameter to improve initial lubrication during press-fit and prevent micro-welding under severe thermal cycling.
