G1000

[schrocky]

We have a brown belly G1000 we use on the farm as an auger tractor, Im out of town visiting my heart transplant donor family and my hired hand called and claims the engine oil is disappearing into the hydraulic...is this even possible ? Im trying to figure out how...anybody ?

That would be an odd one....Only place I can think of would be where the pump bolts to the engine but would think the hydraulic oil would be going into the engine not the other way around.

thats what I thought guess I gotta bring it home to "ole Daves" and rip into it !
 

[t.r.k.]

You don't say if the G1000 is gas, lp or diesel.

With a diesel its possible for the oil to be burning and 'going away' and not be noticed in the exhaust.

Usually the hydraulics leak into the engine because of the pressure differential between the hydraulic pump and the crankcase. That's not good either, hydraulic fluid does not work well as an engine lubricant. That happened on Dad's Farmall Cub and wiped out the rings.

You"ve got a seal out in the hydraulic pump. Had that happen on a G706.

Im wondering if the rear main seal on the engine let loose and leaks?....I have that on my G950.

Right on the money, have had it happen to a few g1000s over the years. Both times we just replaced the seal in the hydraulic pump, also make sure hydraulic filters arent plugged.

Thanks Guys it seems as tho the seal is the issue....never would have thought eng oil could do that but it appears the seal is on the suction side of the pump
