My hyd pump leaks where it goes into the transmisson housing. I&T manual shows how, but have any of you removed one before. This on a 8070 and it looks like there are 2 o rings that need to be changed. Thanks for any help!

Randy there are 3 7/16 bolts that hold the pump in the rear end aand all the lines also the 10 3/8s bolts on the plate that you have to take down to get to the screen that has to come out before you try pulling the pump out also need to drain the oil and good luck the o riongs we been getting don't always stop the leak I think they send to small of rings Niel
