Bobcat 324 Question...what these two bolts?

[mykubota4x4]

Hey Folks
Being new to the machine, wanted to change oil & a tech at bobcat suggested there is a drain plug, I went n loosened one of the two bolts only to realise its a dry one (kinda spring loaded) & now i cant put it back. Any idea what this bolt is for. There are two of them in like 3-4 inch apart under that metal frame right below the engine.
BTW Oil change on these were through the hose at the back with a CAP nut (22mm) which i found out thru Youtube. Thanks in advance.

Take a look at the 324 pages on Bobcat Parts Online for the upperstructure and see if anything looks familiar. I'd thought it might be for the rear door latch, but that shouldn't be under the engine.

I wonder if its part 4 or 5 in the above diagram of the track tensioner. From what i see the 2 screws were one behind other (with ref to front to back of machine placement)
