This
piston can be used to replace the 9Y4004 in select applications
where piston seizure may be caused by high horsepower and/or
temperature conditions. The oil cooling gallery, built in the
crown of the piston, helps to reduce operating temperature
of the piston and the risk of quarter point scuffing or seizures
that are common in overheating conditions.
When updating a 3406 from a 9Y4004 piston to the 1601131 piston,
the cooling jets must be changed from a single configuration
to a dual configuration. Jet numbers 1663650 (with .3228" bolt")
or the 1979336 (with .4016" bolt) dual cooling jets replace
the 7W4990 single cooling jet. The oil pump must also be updated
from the 0R9448 to the 0R9449 engine oil pump group. Additional
information may be found in Caterpillar® Service Magazine
#SEPD0827-00 or other publications for details on applications
and required component upgrades.
