My 773 G series has been a great machine, but today blew its hydraulic oil cooler, that mounts over the radiator. I was advised that there is a tool to remove the hydraulic hoses, however finding one is another question. They do not screw in, but just push and snap. Anyone know about this tool, and where it can be obtained?
 
The tool is made by AreoQuip , the 773 should be the #10 (5/8) size , bigger machines use the #12 (3/4) size , you can get it from an AreoQuip dealer or from the Bobcat dealer , who will get it from OTC Tools

Hey Fishfiles. Thanks.
 
Hey Fishfiles. Thanks.
The fitting is a push/snap together fitting , I forget the name of it , I think it's Push-Lock , there is a internal ring , o ring and a back up ring which goes inside the female side and when pushed in it snaps together very easy , you can buy a kit with the 3 parts in it for like $10 to repair a leak at the fitting , it is very hard to get it out with out the tool , but possible , the tool resembles a widened out tuning fork , I don't like this fitting , machines that use a hammer have a tendency to pop off the hose at the filter head where the fitting is also used , I think this mostly happens on machines that have a low nitrogen charge and have a wicked back pressure on the system , you know when the hoses to the hammer violently shake around , the T 140 is notorious for popping off , It's been out for a while now and the fitting is available from a AreoQuip/Eaton dealer so hoses can be had after the dealer , I have had to change a few oil coolers because the inside the welded female on the cooler gets worn out and the hose won't stay on , I have a few times had the radiator shop weld a JIC fitting to the cooler and replaced the hose with the old school JIC type , I have also wrapped tie wire around the fitting to the hose to keep it together , Bobcat gets $43 dollars for each one of the tools , it could be easily copied with a plasma cutter or touch , the tool will bend pretty easy so care needs to be used and not brute force ----------------- Tazza , could you give a brief description of how to post pics again

^^ what Ken said :)
Any issues, just send them to Ken or myself.
It makes me wonder why they would change from something that worked just fine to this new coupling. The old JIC fitting setup worked just fine, it was cheap and worked. Why change to something that is more expensive? with anything that can be *easily* un-coupled you are just asking for trouble.
I guess its like car makers, they get an engine and transmission that works really well, but decide lets re-design the whole lot for the next model.... I have never understood that logic, would save millions in R&D.... But what would i know rite?

Hey Fish. As you told me the 773 has a 5/8" fitting. I found the tool up in Ohio, had to be shipped to the distributor, who would get it to me a day or two later, at great cost. Bobcat had some for their use, and were not about to lend them to me. Ford big truck breaks, and possibly some high pressure lines on Power stroke engines, require a similar tool. One is available at most auto parts stores. They look flemsey compaired to the one you recomended, but it worked great. If you are a pro, working on these machines, I would recommend the tool you recommended, but for those of us who do this every several years, this worked great. Sadly the cooler was not repairable. It had rusted through. Was not aware that the cooler has to be removed, as part of regular maintenance, cleaned, and the area between the cooler and the radiator also needs to be cleaned, or vaccumed. Bobcat, and Fedex over night are pretty proud of their parts and serrvices, and this repair may have been avoided or put off with some regular cleaning. Hope this helps someone else. Thanks again for your help. montreat builder
