Question about John Deere 420,1020,2010,2020,2510,2520 Tractor Float

1 Answer

The hydraulic steel line on my 2010C bucket loader broke and I dumped a good amount of fluid before shutting everything off. Replaced line and filled tank up, everything worked fine for about 1/2 hour, then tried to pull back a stump,when instead of pulling, the whole boom lost its' lift. Now the boom won't stay lifted, drops right down. Bucket works normally. No visible leaks.Oil level ok, used Hygard from JD.

Like other hydraulic systems, there is probably a procedure for bleeding the lines after loss of most of the fluid. You may still have air trapped in the system and once it works its way to the cylinder, the cylinder is working with air instead of fluid and the air compresses instead of doing work.

My jd 3039r hydraulics. Loader and backhoe buckets lose position when running or shut down. Do I need to bleed hydraulics? If yes, how?


no
hydraulic system self bleed from repeated use
what you have are piston seal worn, cylinder walls damaged allowing bypass of oil or faulty control valve units

How do you bleed the hydraulics on a Bobcat 751 skid steer loader?


Hi Joseph:
Usually hydraulic components will "self clear" any air in the system just by trying to cycle through the functions a few times.
Have to ask the question............
Did you remove and replace the hoses one at a time, or did you take them all off at the same time?
The reason I ask is............ Could there be a remote possibility that any of the hose onnection locations were switched?

Remote valves not working.you can raise frontend loader but it want come down. also the bucket want work . change all hyd fittings.and check pump pressure thats good. need help.


Change the filter. If you can lower the loader by loosening a line at the valve, suspect the valve. All lines usually dump to tank at the valve. Make sure that line is ok. If any valves are electric, suspect them even more.

How do i get the master clinder off?? i have the lines and the bolts off but i cant pull it lose


Hello there, The slave cylinder for the hydraulic clutch is mounted to the very front of the transmission and is only held in place with two bolts and the hydraulic line, see item #42 (x2) and item #26 in the attached photo.You might as well let the old hydraulic fluid drain completely and fill with fresh fluid when you get done. I would take the hyraulic line off the slave cylinder and put it in a jar. Then open the master cylinder cover and let it gravity drain completely. This will allow you to replace all the parts with a minimal amount of fluid getting all over. Remember, brake fluid damages car paint!The clutch master cylinder is a little bit more tricky in that you have to get under the dash to remove the bolts holding it in. Other than that, you might have to take your old reservoir and attach it to the new master cylinder unless your new one comes with a reservoir. I doubt it will and you don't need it to anyway. Item #37 and #43 are the studs and nuts you will have to release to get the master cylinder off the firewall. Of course pulling the tube to the reservoir and the hydraulic line should be done before removing the mounting nuts. There may be a clip holding the clutch pedal linkage to the clutch master cylinder push rod.Once everything is reassembled and everything is tight, fill the master cylinder reservoir and then loosen the bleeder screw on the slave cylinder. You can depress the clutch pedal to force brake fluid from the master to the slave but if it goes like mine did, once I got the fluid running, it forced out all the air! I put a rubber hose over the bleeder screw and put it in a jar partially filled with brake fluid and kept adding fluid until no more air bubbles came out of the tube. You will know when everything is ok because the clutch pedal doesn't seem to want to come back up unless there is sufficient pressure in the clutch to force it back up. Buy about a quart of brake fluid to flush the lines and leave it topped off. Good luck...

I need to know how to change the transmission fluid in my 1998 bravada


There are a few mays to do this, you could take it to the transmission shop and have them service it or you can do it your self. If you want to replace the transmission fluid and filter you have to drop the transmission oil pan, your going to have to remove the oil pan bolts and shifter linkage to the 4X4 and once the pan is off. Just pull off the oil filter from the valve body and replace the O ring with  the new O rings to ensure the new filter will not fall off from the valve body and then re-install the everything in revers. Once the pan is back on refill the transmission with AFT and test drive. The other way you can drain the system with out the filter replacement is to disconnect the transmission line at the radiator on the passenger side, top by the radiator cap. Connect a hose to the line to a large bucket and start the engine, the fluid will drain fast so be ready to turn the engine off so you don't burn out the front pump. you can also judge how much fluid is in the transmission by the amount of fluid is collected in the bucket. Note: make sure you have a large bucket. Once you think you have drained enough transmission fluid, turn the engine off and re-install the transmission line to the radiator and refill the transmission with AFT. 
Automatic Transmission, 4L60-E Initial Fill..........4.7 liters
Automatic Transmission, Total Fill  4 speed 4L60-E..........10.6 liters

Good luck and hope this helps. Keep me posted, be glad to answer any questions you may have.
