Weep Holes
High pressure seals and connections fail gradually and begin leaking slowly. Weep holes are
located at every threaded high pressure connection to provide a vent for internal leaks. Water or
oil dripping from a weep hole indicates one or more internal components are beginning to fail.
Table 8-3 lists the location of the weep hole, the possible source of the leak and the corrective
action required.

for linear scratches or scoring.
Water leaking from the weep
hole on the hydraulic cylinder
head flange
Failed high pressure seal
assembly
Replace the high pressure seal
assembly.
Damaged plunger
Check the plunger for
longitudinal scratches or flaws. If
detected, replace the plunger or
return to KMT for evaluation.
Seal material buildup on plunger
Polish the plunger surface
following the procedure, Plunger
Maintenance.
Damaged high pressure cylinder
Check for scratches, grooves or
material buildup on the inside
diameter of the cylinder. If
detected, polish the bore
following the procedure, High
