Hi folks- I've got a 2001 Bobcat 773 turbo and need to change the hydraulic fluid. Wondering if anyone has any experience with this. Also can someone give me a link to the manual for that machine? I had a great link before but lost it. Thanks. Also, someone told me to run the rpms wide open to save the hyd pumps. I haven't done that, preferring to run the machine about 2400 rpm, which is 200 or so below max. Any comments appreciated.

I drain my fluid by running the machine at idle and pumping it out of the quick couplers. As soon as it starts to spit i shut it down. Re-fill with oil and change the filter, re-start and it should be good to go. Some don't like doing it like this as they feel the pumps run dry, but they never do, yo always have a film of oil. If you kept it running then yes, it would cause damage. Its you call if you do it this way or not though.
If the oil is not contaiminated you can suck the oil out of the reserve tank and re-fill too.
As for running the machine flat out, i never run mine like that. It goes on the conditions, half to 3/4 is generally all i run. Its really just something you do by feel. If the machine bogs down too much, bump it up, if its noisy when digging or turning, bump it up a bit too.

Thanks Tazza. Do you have a link to a repair manual for that machine. I got it on this sight about a year ago. Thanks again.

I don't. but if you send OldMachinist a nice email with your model number and serial number, he should be able to give you a link.

You can go to tradebit.com and download the whole service manual but I wouldn't recommend printing the whole 965 pages I printed this weekend. eBay has the hard copy for 110 for my t250. Tradebit is 9.95. After my time, paper, and ink, the hard copy is a good deal.

I wonder if someone like Staples would print it cheap? The world seems to be going towards including a card with your product saying "everything you need (in life) is on the internet". The manufacturer needs to write the pubs in the first place. So there is no savings there. But if printed it would be printed on high speed ink & paper printers at a very fast rate and for pennies. If consumers want to print it it costs mucho bucks in ink/toner and paper and time and if you cannot duplex, you end up with a bigger stack of paper. For things that are dirty (and you are likely to be dirty) paper seems better since I for one do not want to get dirt & grease on my computer. Also for products that provide access to the internet, one might need a printed manual. Having it on the net in addition to paper would seem the best idea. Somehow paying Bobcat $100 for a repair manual to fix things on your Bobcat (that Bobcat built) that you would prefer not break in the first place seems odd.
Absolutely! The discussion you provided is centered on maintaining a Bobcat 773 turbo skid steer, covering topics like changing hydraulic fluid, locating and acquiring the machine's repair manual, and optimizing machine performance by managing RPM levels.
Regarding changing the hydraulic fluid, Tazza suggests a method involving running the machine at idle and pumping the fluid out of the quick couplers until it starts to spit, then shutting down the machine to refill it with oil and change the filter. They emphasize that the pumps don't run dry during this process due to a film of oil always being present.
When it comes to acquiring the manual, OldMachinist is recommended as a source by Tazza. Ironmule suggests visiting tradebit.com to download the service manual, cautioning against printing the extensive 965 pages due to cost and effort. eBay is also mentioned as a source for purchasing the hard copy, and mrdeere1959 adds that the dealer sells it for $101.45.
There's a conversation about the costs and practicality of obtaining manuals, with some users discussing the value of having printed manuals versus digital ones, cost implications, and the practicality of printing large documents like these.
The main concepts covered here relate to:
-
Hydraulic Fluid Change: Techniques for changing hydraulic fluid, concerns about pumps running dry, and methods to prevent damage during the process.
-
Manual Acquisition: Sources for obtaining the machine's repair manual, including OldMachinist, tradebit.com, eBay, and dealership options, along with discussions on cost-effectiveness and preferences between digital and printed manuals.
-
Optimizing Machine Performance: Discussions on RPM management for the Bobcat 773 turbo, considering conditions and adjusting RPM levels based on machine behavior.
Each of these discussions delves into practical hands-on knowledge about maintaining and operating a Bobcat 773 turbo, reflecting an understanding of the machinery's nuances and the community's experience-based wisdom.
