hydraulic fluid.

Hey all, back again with another disaster. Actually a product of solving a disaster. I got in an argument last week with 3ft hole full of water while clearing the road. Long story short, I got sucked into the ditch which happened to have water that some how didn't freeze. I wasnt able to get the time time to yank it out until the weekend and it had completely frozen in by then. 7 hours of messing about with a dohatsu dozer, a tractor and 5 friends got it out but we nicked the elbow at the hydraulic pump. My question is does the pump share oil with the transmission or am I safe to drive it back to the house? About a mile.

It might help to know what tractor your talking about. If you have a front mount pump it won't share fluid with the tranny but will shell out the pump if you run it with no oil going through the pump. If you nick a suction line it will suck air, if pressure line, it will empty the tank and burn up the pump.

Drain the hydraulic tank - with bucket at tank and another at that damaged elbow - then drive her home but tie loader or blade up before you start draining the fluid!

So I can drive it home and no harm to the pump? Also, are the hydraulic lines clamped on somewhere I can't see. Both ends are undone but it wont move.

NO NO there must be fluid in the pump when the pump turns or you FRY the pump in less than a minute!

I haven't moved it yet, but it turn out it wasn't the line, but the elbow fitting of the small hose going into the pump. I have been doing some research and it looks like these are hard to come by. is there anywhere that would carry such a thing?

That should be a very common fitting. Most of the ones I've seen were class 300 cast street elbows like this

I used a high pressure rated street elbow like this one

You should be able to find these at any plumbing (for class 300) or industrial/Hydraulic supply house.

How many hoses on that pump 2 or More? Also not all hydraulic pumps use pipe fittings. Can you furnish a picture?

Thanks for the advice everyone. I'm back in business. At least until I break something else.
