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.
