MF 7495 hydraulic oil transferring to backend!

[Bumble Bee]

Our 7495 seems to be slowly transferring oil from the hydraulic tank to the backend. Everything is driving ok.
Does anybody have any ideas what this could be?
I was wondering where the braking system gets its oil from. Could it be leaking in through the carden brake etc?
Any advice appreciated.

Try capping the cardan brake line and see if it still happens.

My thoughts are that the seal between the hydraulic pump and transmission is likely to be the culprit

If your transfering hyd oil I reckon the hyd pump drive shaft has a grove in it where the shaft seal sits.

That sounds like a likely culprit. Had something very similar happen on our JCB loadall. The hydraulic pump seal went and it filled the engine with hydraulic oil!

Thanks for your help.

Is it a cab off job or a case of removing the tanks and accessing it from the sides?

On fendt you could tip the cab forwards to get to the top but 7495 you could jack the back of the cab up will have to take fuel tank off

Is it a T2 or t3

Looks like the easiest way might be from the side and below if i take the 4WD propshaft off. Just means I'll get showered in oil and muck.

Normaly have two of us doing it one on top and on underneath remember to take the bungs out of new pumps had a apprentice leave them in once test the brake accumulator whilst the tank is off and lift the bonnet up before jacking the back of the cab up otherwise the can smash the front window
