What is this?

Well, I was thinking the same thing, but I have a dipstick to check hydraulic oil, another fluid check for transmission, plus another for differential? What else is there? Does the hydraulic have a fluid check plug and a dipstick on a 63 Ford 4000?

My 3910 does. Makes the job of refilling quicker. You don't have to keep checking the dip stick while filling. Parts inside displace the oil at different rates depending on the oil level. The dipstick is used to check the level while in service.

looks like it's down there by the bottom of the hyds sump.

On my NAA, I blocked that top cover, then toop pressure off that plug to run to a remote valve.

If I'm looking at that plug right ( and I am looking at it on a 2" screen.. ).. that should be open to pump output after the relief.

you CAN have remote hyds and leave it too... it's just a plug in an oil galley.
