Application:
T400743 is the current Perkins service number for the exhaust-valve
guide used on 6-cylinder 1506A-E87TAG, 1506D-E87TA and 1506D-E88TA
diesel engines. These engines are installed in FG-Wilson P165-5,
P200-5 and P220-5 generator sets, JCB 457 ZX / 467 ZX wheeled
loaders, Dressta TD-15R / TD-20R crawler dozers, Bomag BW226D-5
single-drum rollers and Atlas-Copco XAS 375 / XATS 400 portable
compressors, covering 200-300 kW industrial, construction and
power-generation equipment that must meet EU Stage IV / EPA Tier
4-F emission limits worldwide.
Technical specifications:
The body is salt-bath nitrided to a 0.02 mm depth exceeding 650 HV
and carries an internal spiral oil groove that maintains roundness
within 5 µm after five million cycles and extends service life
beyond 8 000 h in stop-start genset duty, while the chamfered top
lip and centre-less ground h6 tolerance allow press-fit
installation into the cylinder head without reaming and the guide
operates continuously from –40 °C to +250 °C.
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 exhaust gas temperature exceeds 600 °C. The
outside diameter is centre-less ground to h6 tolerance so the guide
can be press-fitted into the cylinder head without additional
reaming, while the internal spiral groove maintains an oil film
that keeps stem temperatures below 250 °C even after 8 000 h of
stop-start genset service.
