Application:
Valve Guide T400742 is a precision-engineered inlet guide produced
for Perkins T4.236 and AT4.236 turbocharged 4.0 L diesels; the same
guide is also specified for the later 1506A-E88TAG2/3/4/5 and
1506D-E88TAG series, so you will find it in everything from 80-120
kVA agricultural tractors and combine harvesters to JP230-300
AE60/AE56 generator sets and common industrial sweepers,
compressors and forklifts that rely on these engines for continuous
high-load operation.
Technical specifications:
The guide is finished to an outside diameter of 15.92 mm so it can
be pressed into the cylinder head with the recommended 0.05 mm
interference fit; the bore is held to 8.00 mm ±0.01 mm to give the
correct 0.04-0.06 mm running clearance on the standard 8 mm inlet
valve stem, while the overall length of 52 mm provides full support
from the spring seat to the port face. Concentricity is held within
0.02 mm to prevent side loading, and the 15° upper lead-in chamfer
speeds assembly and protects the stem during the first hours of
operation.
Material & performance features:
Cast from a high-duty grey iron alloy that already contains nodular
graphite for self-lubrication, each guide is then
plasma-gas-nitrided at 540 °C to produce a 0.02-0.04 mm white layer
with surface hardness above 800 HV; this gives excellent scuff
resistance against today’s low-sulphur fuels while the untouched
core retains toughness to resist cracking under thermal shock.
