I have asked that same question about my 2470...."they" say no. I'm losing hydraulic oil and gaining engine oil. Not fuel in the oil as I have taken the cover off the pump and primed it till it won't pump anymore and no fuel anywhere past the plungers. Also put a new kit in the transfer pump, A pump guy told me to put a drop of oil from the dipstick on a white napkin...if it turns red around the drop it has fuel in the oil.

Send sample of eng oil in for analysis. Ran into this prob once w/results showing high potassium level indicating hyd/trans oil. Pulled eng and found rear main seal bad.

You shouldn't be using straight Hyd. oil anywhere in the 4690. Hopefully you mean Transmission-Hydraulic Oil such as Hy-Tran. Yes, if the rear crank seal is bad, Tranny-Hyd oil will get into the crankcase as the flywheel housing is "wet".

I'll have to do the oil sample. Been running about 30 hours and changing oil. Heckuva job to change that seal...for a old shade tree mechanic. Thanks!
