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.
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.

Free shipping over a hundred bucks... Order some fluids and filters?
hello, I also enjoyed watching your youtube channel. I have a 1980 bobcat 530 that is not getting fuel. If I dump some fuel directly into the carburetor and start it, it runs for a few seconds as the gas gets eaten up. I checked the fuel line and fuel is coming out fine. I am trying to find out where the fuel pump is before thinking of taking out the carburetor. Any help would be greatly appreciated.
Can anyone tell me what part this is? the small part to the right of the carburetor with the black hose connecting from that part to the carburetor? thank you

I saw your question on my Youtube video and responded. I also responding here with the same info in case anyone else is looking for this info.
You are looking at the oil breather tube. It routes crank case fumes back into the carb to be burned. If you have a 530, there is no fuel pump. It is gravity fed. You can easily follow the fuel line from the tank outlet found on the left side of the tank, to a fuel filter, then to the electric fuel shutoff and finally to the carb. Pull the fuel line off the carb and turn the key to the run position. If fuel flows you probably have a partially stuck float valve. Otherwise, you may have a restriction somewhere in your fuel line. I once had my electronic shutoff fail. I temporarily ran a small lawn mower tank directly to the carb to get my Bobcat running so I could get it back to my garage.
You said fuel is flowing from the fuel line, so I would focus on the carb next. I'd look into the float and float valve.
