1980 Bobcat 530

Sorry, I don't have any experience with the pressure relief on the hydrostatic pump.

You were correct on those o-rings leaking. Mine is dripping in same place and thought I seen a drip farther forward. Is there multiple shafts on that pump? I haven't pulled the diesel motor out yet but may start this weekend. Was wondering cause may be way over my head taking that pump apart to get to the bolts on the other shafts. Was that the only one leaking on yours or am I looking at something wrong?

I believe there are four shaft positions on the 530 pump. That was the only shaft leaking on my Bobcat. Take a look at the parts diagram on https://www.bobcatpartsonline.com/#/catalogBrowser. I found the parts diagram under "Hydrostatic System/Hydrostatic Pump". The pump was probably used on a bunch of different models, so they have options to run the shafts from either side. Mine has block-off plates on the right side (facing the front). Good luck on your repair.

Is it possible to get to the bolt on the other shaft just like the one you fixed? I seen a drip coming from forward of the one you fixed also.

I haven't had the front portion of the pump apart, but it looks the same in the diagram. I bet you can get at it the same way. The nice thing about the front side is maybe you can get to it from under the seat.

I will probably just take is apart like you did. I ordered the metal and paper gasket today. As soon as they come in I am going to start on it.

They cant get the gaskets for me. Tried two different bobcat dealers. Both said discontinued. If you dont mind me asking where did you get your parts? Maybe I can order them there and have them shipped to me.

I got mine at the Farm-Rite Equipment in Dassel MN. They are an authorized Bobcat dealer.

Just called bobcat and they think they have a couple of the metal gaskets in the warehouse she thinks.. She added the item to there web site and I ordered it. They are proud of them. $35 for the part and cheapest shipping they had was 5 to 10 day ups for $24.00. They dont have the other gasket.
