How long have oil sample test results been provided? On what other trucks are they provided? I'd bet GovPlanet takes oil and transmission samples on the FMTV series because they can so easily. Just start the engine and open the engine and transmission test ports to flow a sample. Most likely they do not run the engine for 30 minutes, and probably do not purge the hoses to the test ports before sampling either. (That would mean they would have waste oil to get rid of somehow.) The test is probably run on whatever resided in the test hose, plus a little from the engine/trans.
As for taking a sample from the drain plug on the bottom of the engine or trans, we all know that once the plug is out, it's Niagra Falls under there. Imagine trying to pull a 4 ounce sample and put the plug back in? Better have some big buckets ready. Can't see GovPlanet risking that at all.
How many other military trucks have sampling ports?
BTW, Blackstone test on my Allison showed high copper. Blackstone indicated this could easily be initial wear on bushings and thrust washers and not indicative of a problem.
An earlier comment indicated that high copper and iron in a test would indicate worn clutches. I don't follow that at all. Why?
I am in the group who think the provided test results are mostly useless.
