yes if the seal in the front of the hyd. pump goes out it will pump oil into the crankcase

I have and it is relatively easy if no permanent damage is done to the pump. look the link below. Disregard first page till you get to the pump overhaul part.

I'd also like to add that you need to find out why the pump shaft seal failed.
Was it just a wear issue and went? or was the pump deadheaded perhaps by a bad hyd valve, non operational relief or relief set to high.. or perhaps even a mis-seated quick disconnect.
on a positive displacement pump, it doesn't take much obstruction to pop a shaft seal.. oil has to go somewhere.
good luck on the issue. post back what you find.

have you only used it a few minutes and it filled up quick.. or was it a few hours use with gradual fill up?
did 3pt or other remote hyds work normal?
if it was a slow leak.. it might simply be a tired seal. do check the shaft as well for damage or wear where the seal rides.

It was a slow leak. Crankcase level looks to be a quart/quart 1/2 high. Hydraulic reservoir is barely showing on the dipstick. I last checked the fluids maybe 6 hrs run time ago and everything was OK. Lift worked normal. It will still raise my 5ft. bushhog at idle.

slow leaker then.. not a catastrophic dead head.
