PREVENTIVE MAINTENANCE CHECKS AND SERVICES INCLUDING
LUBRICATION INSTRUCTIONS -- CONTINUED
Check for loose bolts. A loose bolt can be difficult to spot without actually applying a wrench. You can often tell by
loose or chipped paint around the bolt head and bare metal or oxidation present at the base of the bolt head.
Hoses and Fluid Lines and Fittings
Check all hoses and lines for signs of wear (deterioration or cracks), leaks, loose clamps and loose fittings. A stain
around a fitting is a sign of a leak. Tighten, repair or replace hoses and fittings. After completing a repair or re-
placement of hydraulic components, always start up the hydraulic system, pressurize the repaired/replaced compo-
nents and check for leaks in the pertinent fittings. Tighten as required.
If inserts are damaged when removing a component, notify support maintenance.
Corrosion Prevention and Control
Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern. It is important that any corrosion
problems with this item be reported so that the problem can be corrected and improvements can be made to pre-
vent the problem in future items. Refer to WP 0001 00 for more information on Unit level CPC.
Classification of Fluid Leaks
Equipment operation is allowable with minor leakage
(Class I or II). Consideration must be given to the fluid
capacity in the item/system being checked/inspected.
When in doubt, notify your supervisor. When operating
with Class I or II leaks, continue to check fluid levels as
required in your PMCS. Class III leaks should be re-
ported to unit maintenance supervisor.
Class I: Seepage of fluid (indicated by wetness or discoloration) not great enough to form drops.
Class I: Leakage of fluid great enough to form drops but not enough to cause drops to drip from item
Class III: Leakage of fluid great enough to form drops that fall from item being checked/inspected.
