New Holland ts makes funny noises

[LLX001]

I'll link a video, what do you think the noise is? It only appears after about an hour of work, so I guess its temperature related. I tried to pinpoint the source of the noise and if I have to guess it comes from somewhere the clutch valve pack. I don't feel any difference in behavior while hot or cold. Shifts, steers and lifts as usual.

Air con clutch/compressor?

It was off during the video, and it comes roughly from underneat the cab :/

Are the spools in neutral?

Sounds like something hydraulic is running against pressure. Are they electric or cable spools?

 

[agrimax]

They would be cable operated in a TS.

Would it have a closed centre load system on it? CCLS? How do you get it to do it,or does it appear on it's own?

Check the tube that the transmission dipstick goes down, on ours it came loose and made the same sort of noise as it vibrated against the transmission housing

Yes they are

Yes it has EDC and CCLS variable displacement piston pump. I don’t do anything. After a cold start and about an hour of work it randomly appears. Thats why I think its temperarure related

I regulary check trans oil and it doesnt seem to contact with anything but I’ll check it, thanks

May we ask what the tractor would be doing for the hour before the noise starts?

Sure, sorry I should have said that. If I for example just cruise on road it needs a good 2 hours to appear, but last time when I started baling (Scarabeus M1370) it started exactly an hour before start. An another time I was harrowing with a small one (just as wide as the ts) it started well after 4 hours. (Though I was going in H1 and H2 at just 1400 rpm, so I guess it took more time to heat up?!)
