TM 5-4310-343-35
Trouble
Probable Cause
Remedy
Excessive blow-by.
Note: To isolate the
(continued)
stage responsible for
the excessive blow-by,
drop the delivery pres-
from maximum pressure
of 3000 psi to the pres-
sure corresponding to
the 3rd stage output.
If excessive blow-by is
still present, drop
pressure to correspond
to 2nd stage output and
then to the first
stage output. Note at
which stage the exces-
sive blow-by falls off.
The faulty stage will
probably be the one
with the next higher
delivery pressure. Re-
place faulty cylinder
or plunger or piston
assembly.
