TM 9-2350-277-10 PREVENTIVE MAINTENANCE CHECKS AND SERVICES — Continued 0090 00 Fluid Leaks You needto know how fluid leaks affect your carrier. Definitions of the types and classesof leaks are given below. You need to know them to determine the condition of your carrier. Learn them. REMEMBER: WHEN IN DOUBT, NOTIFY UNIT MAINTENANCE! NOTE You are allowed to operate equipment with minor leaks (Class I or II). How much fluid each item or system being checked or inspected can hold must be considered. When in doubt, notify unit maintenance. When operating equipment with Class I or II leaks, continue to check fluid levels as required in your PMCS. Report Class III leaks to unit maintenance for corrective action right away. Any fuel leak will make the carrier NOT READY/AVAILABLE. CLASS I Seepage of fluid is not great enough to form drops, but is shown by wetness or color changes. CLASS II Leakage of fluid is great enough to form drops, but drops do not drip from the item being checked or inspected. CLASS III Leakage of fluid is great enough to form drops that fall from the item being checked or inspected. LUBRICATION Service Intervals — Normal Conditions For safer, more trouble-free operation, see to it that your carrier is serviced when it needs it. Service Intervals — Unusual Conditions Your carrier will often need extra service and care when you operate under unusual conditions. High or low temperatures, long periods of hard use, continued use in sand, water, mud, or snow, will break down the lubricant. Then you have to add or change lubricant more often. But during periods when the carrier isn’t used, the service intervals can be stretched out. Army Oil Analysis Program (AOAP) AOAP is an effective maintenance diagnostic tool and is not a maintenance substitute. TB 43-0210 and TM 9-2300-422-23&P must not be interpreted to mean AOAP minimizes, in any way, the need to employ good maintenance practices and strong maintenance disciplines. Sampling Requirements: Samples may be taken without WARMING a component to operating temperature if equipment has been operated within the last 30 days. If equipment has not been operated within the last 30 days, the components must be brought to operating temperature. These requisites apply to both routine and special sampling. Oil samples must not be taken immediately after oil is added. When oil sampling valve is not available to take oil sample, use a vampire pump. Frequency Of AOAP Sample: Every 60 days obtain samples of engine and transmission oil and send to the nearest AOAP Laboratory (TB 43-0210 and TM 9-2300-422-23&P). Take samples as near the prescribed interval as possible. If sampling at the prescribed interval is not possible, a 10 percent variance before or after the scheduled interval date or miles is permissible. The need for on-condition oil changes will be determined by the AOAP Laboratory. 0090 00-4 Change 3
