Getting an oil sample.

Getting an oil sample from the 815F compactor's transmission AOAP valve is a messy job.

Getting the oil to flow evenly into the sample bottle is next to impossible.

Make the job easier by attaching -in plastic tubing, NSN 4720-00-964-1433, onto the valve's fitting. That way the oil flows through the tubing and directly into the bottle.

And to get it right, start the compactor's engine to pressurize the system. Once the oil starts to flow, flush a small amount of oil from the line to clear out contamination. Then fill the bottle from the valve's tubing.
