OIL ANALYSIS PROGRAM SAMPLING PROCEDURES
Oil samples must be submitted to an assigned Army Oil Analysis Program
(AOAP) laboratory every 25 engine hours or 30 days, whichever comes first, in
accordance with TB 43-0210.
Three oil sampling valves (1) are located on the oil sampling manifold (2). The valves are identified by the plate (3)
above the valves (1), and are used to sample oil from the following:
-- -- Samples oil from the entire vehicle hydraulic system.
HYDRAULIC OIL SAMPLE
---- Samples vehicle engine oil.
ENGINE OIL SAMPLE
POWERTRAIN OIL SAMPLE ---- Samples lubricating oil from the transmission and steer unit.
When a lubrication note specifies that an oil sample must be taken, use the following procedures:
Open engine intake grilles (TM 5-2350-262-10).
Ensure that oil to be sampled is at its normal operating temperature (TM 5-2350-262-10).
Open valve (1) of system or component to be sampled, and drain at least 2 oz (59 ml) of oil into a container.
Close valve (1), and discard this oil.
Place sample bottle (TB 43-0210) under valve of system or component to be sampled, open valve (1), and fill
sample bottle to approximately 1/2 in. (1.3 cm) below neck of bottle. Close valve (1).
Send oil sample to AOAP laboratory.
If no other tasks will be performed in the engine compartment, close engine intake grilles (TM 5-2350-262-10).
