WESPC Intake Valve 3142L081 For Perkins 1004-40T 1006-60T T6.601 CCW6.601

WESPC Intake Valve 3142L081 For Perkins 1004-40T 1006-60T T6.601 CCW6.601

Application:

This intake valve is machined for 4- and 6-cylinder Perkins 1004-40T, 1006-6, 1006-60T, T6.601 and CCW6.601 naturally-aspirated and turbo-charged diesels, which power Massey Ferguson 5460-7490 tractors, 7270-7280 combines, Landini 8860-9880 row-crop tractors, JCB 530-70 Loadall, 3CX/4CX back-hoe loaders, Atlas-Copco XAS186 & Doosan G50W portable compressors, FG-Wilson P110-4 & P135-4 generator sets and a wide spread of Bobcat, Case and New Holland machines that use the above engine families world-wide.

Technical specifications:

Valve-head Ø 43 mm, stem Ø 8.9 mm, overall length 122.9 mm, seat angle 30°; stem tip is induction-hardened to 52-58 HRC while the lower stem carries a 0.03-0.05 mm gas-nitrided layer giving > 850 HV surface hardness to resist scuffing during prolonged high-boost operation typical of the 1006-60T engine. Head and stem are CNC-finished to Ra 0.2 µm to guarantee positive sealing and uniform heat transfer every cycle.

Material & performance features:

Hot-forged from 21-4N (5Cr21Mn9Ni4N) austenitic steel that retains 900 MPa tensile strength at 700 °C, the head is flash-chrome plated (≈3 µm) to cut friction and valve-guide wear while the nitride layer on the stem prevents micro-welding and maintains stable lash over thousands of hours in stop-start field service; the tulip profile is swirl-polished to improve flow coefficient and reduce pumping losses, giving cleaner combustion and lower fuel consumption across the 1004/1006 engine map.
