WESPC Valve Guide 3343F002 For Perkins 4.212 4.236 4.248 6.354 1004-4 1004-4T 1006-6

Application:

This intake-valve guide is machined for the naturally-aspirated and turbo-charged Perkins 4.212, 4.236, 4.248, 6.354, 1004-4, 1004-4T, 1006-6 and 1006-6T engines, which means it is fitted to Massey Ferguson 165-399 series tractors, 30-50 industrial loaders, 550-890 combines, Landini 7860-8880 row-crop tractors, Claas 65-75 forage harvesters, JCB 3CX/4CX back-hoes, New Holland 1116 swathers, 1495/1496 mower-conditioners, Volvo BM 2200 forklifts, FG-Wilson P100-4 and P135-4 generator sets and a wide spread of irrigation, construction and marine auxiliaries that use the above engine families world-wide.

Technical specifications:

The guide is machined from centrifugally-cast pearlitic cast-iron to an outside diameter of 15.9 mm, inside diameter 9.52 mm and an overall length of 58 mm; the bore is micro-honed to Ra 0.4 µm to give the valve stem a consistent 0.04-0.06 mm running clearance that prevents side-thrust wear while still allowing adequate oil film for cooling.

Material & performance features:

The iron matrix is alloyed with 0.7 % Cr and 0.3 % Mo to raise thermal conductivity and creep resistance, then salt-bath nitrided to give a 0.02 mm compound layer > 650 HV that resists scuffing and micro-welding when intake air temperature exceeds 200 °C; the outside diameter is finished to h6 tolerance so the guide can be press-fitted into the cylinder head without additional reaming, while the chamfered bottom lip aids assembly and prevents bore distortion.
