I'm looking at a Dynahoe 490 with the 4-53 Detroit. Unknown year, i haven't inspected in person. My concern is the seller says it has no brakes at all. I have found no information on the brake system of these machines so I am just looking for information about the brakes and their repair. I need to know if I am going to be capable of repairing them myself. Any other info about the 490s is also appreciated. I have already requested to join the yahoo group for dynahoe backhoe owners, but haven't been accepted yet. Thank You.
I have a Dynahoe 190 with the 3-53. So far it has been a great machine, but I also have no brakes. When I got it, the brakes worked, but have slowly faded away to nothing. It doesn't bother me much as I only use the machine on my own property. I haven't looked into it much but everything else I've done on this machine was relatively straight forward. I'm also a member on the Yahoo group. It is a great resource for information.
The brakes are "standard" hydraulic brakes, right? With a master cylinder and wheel cylinders? They shouldn't be that hard to figure out, and the parts are out there, just maybe a trick to find the part numbers, or make something else fit. I can't help, but the yahoo group is the best place to go I know of. And I woudn't be afraid of fixing the brakes as long as you can look at it, verify how the brakes are supposed to work, and see that everything else works.
If the brakes are a standard style then it shouldn't be a problem, just wanted to make sure. How is it to drive without brakes with the automatic? I have driven many tractors without touching the brakes, but they have all been manuals. I just got accepted into the Yahoo group so I'm going to peruse there and see what I come up with. Thanks.
It's not to bad as long as your on flat ground. Mine doesn't want to move when put in gear until you give it some throttle, which helps. I should really get around to fixing my brakes though.
