Leakage of fluid great enough to form drops, but not enough to cause drops to drip from item
Leakage of fluid great enough to form drops that fall from the item being checked/inspected.
Equipment operation is allowable with minor oil and coolant leakage (Class
I or II). When operating with Class I or II leaks, continue to check fluid
levels as required in PMCS. All leaks should be reported to the next higher
level of maintenance. Failure to comply can cause damage to equipment.
Procedures Column. The procedures column of the PMCS table tells how to perform required checks and
services. If required tools are not available, or if a procedure indicates, complete DA Form 2404 and
submit it to the next higher level of maintenance.
The terms "ready/available" and "mission capable" refer to the same status. The
generator set is on hand and able to perform combat missions. Refer to DA
"Equipment is not ready/available if" Column. This column tells when and why the generator set cannot be
Reporting and Correcting Deficiencies. If the generator set does not perform as required, refer to Chapter
3, Operator Troubleshooting, to diagnose the problem.
Removal of Assemblies/Equipment to Perform PMCS. There is no requirement to remove
assemblies/equipment prior to performing PMCS.
If generator set must be kept in continuous operation, check and service only those
items which can be checked and serviced without disturbing operation. Perform
complete checks and services when the generator set can be shut down.
The generator set can be operated continuously at any load from no load up to and
including rated load. However, at light loads an oily residue (unburned fuel oil)
may occasionally be noticed in the exhaust system outlet and around connection
joints in the exhaust system. This residue is caused by the inability of the fuel
injection system to consistently meter the small amount of fuel required to operate
at these low load levels and is not a defect in the fuel system. The oily residue
could affect engine performance and create a cosmetic problem on and around the
generator set. Operation at rated load will burn off this oily residue. The length of
time required at rated load depends on the amount of residue. This oily residue can
be prevented by increasing the electrical load on the set.
