Have case 504bdt engine and it's filling with hydraulic fluid fast. Can't find where it's comming from. Main pumps are attached to crank at flywheel but no leaks anywhere. The crankcase filled with 8 gallons of oil in 4 minutes. Thanks for your help. Controls won't work in any position. Never used hyd. oil before and sight glass in now down 2 inches. Can't find any Hyd attachedments except at flywheel area.

I am not familiar with the 504 engine as the ones in the UK had a Deutz.the main hydraulic pump was driven from the flywheel,the servo pump was driven from the front of the engine from the timing train,should the shaft snap or the seal fail you would get hydraulic oil in the engine,it is only a small pump to work the servo system,look around the injector pump and the opposite side and you should find it,it will have the hydraulic lines attached to it
