hi there joedorava

is there input to pumps , are there any leaks in the system either oil / air

have you purged all the air from the hydro units and wheel motors

if air is entraineed in oil , you may get alot of noise from caviatation in the pumps and wheel motors also heat , and vibration and no movement until all the air is gone
top up oil to correct level

caviatation can be quite destructive on pumps etc

i assume you used the correct hydraulic fluid for the unit in question

have you checked changed hydraulic filters when changed hydraulic fluid ?

other than that cant give any more info

What causes the hydraulic pump drive shaft t22915 to break on my jd 2640 tractor

failed pump gears or relief valve not operational
if the gears are badly worn or the idle gear shaft is worn , the teeth will bind or jam in the housing
if the relief valve is faulty , the oil has nowhere to go so it locks the gears resulting in broken shaft

I need advice , the hydrolics have stopped working and there seems to be no pickup from pump what are common issues with hydrolic pump failure

Hello David Maly,

hydraulic systems are wonderfully simple.
Your trouble options
No belt...
No fluid...
blown hose or
defective pressure bypass... (letting all energy pass through)..

It is also possible your pump impeller had separated from the drive shaft...

Your first trouble shooting is going to require you to verify hydraulic pressure (fairly simple plumbing project)...

Check out industrial sales like Grainger or Northern Tools...

Mahindra 2615 2007 tractor is spraying hydraulic fluid by two of the brass couplers underneath the lever. I wondered for troubleshooting should I just repair/replace tractor components .

Hi Benjamin:
I have a fleet of equipment that have hydraulic components, and one of the most regular maintenance tasks is replacing failed or worn components.
Running hydraulic equipment with leaks present is a real safety hazard as the part could fail resulting in hot high pressure fluid being sprayed unrestrained.
Please, do not run the machine until you replace the defective part.
Hopefully there will be a local hydraulic hose shop that can assist you.

The rear end of the SUV locks down like it has been lowered or there is way too much weight in the rear of the car. It's like the shocks colapsed.

What's the make and model vehicle? There are several makes out there - most famously Land Rovers - that have air suspensions. A failed pump or opened system will produce the result you mentioned. There are other systems where hydraulic fluid is used along with an engine driven pump to set the suspension. Mercedes was famous for doing that for a while.

Good luck.

I have a john deere 316, the other day i was moving snow with it and all of the sudden it lost all power to the hydrostatic and to the front end quick attach. I was wonder what would cause this and how to...

First check level of hydraulic oil. Sight plastic tube just above and to the right of the hitch. Should be in the middle of the tube.

How long since you changed the hydrostatic oil filter under the seat deck?

Next see if the small splined shaft is turning btween the seat deck and the transaxle from the rear of the tractor. If not, it sheered a key in the hydrostatic drive shaft from the motor to the drive. (Had this happen to me)

Check the lever under the right side fender that disables the hydrostatic transmission to allow the tractor to to be moved without dragging the wheels. Make sure its not in the wrong position.

If all these are ok then the hydrostatic pump has failed.

Hello expert, my recently bought XJ12 (XJ81) constr. 1994 fails to control the car´s height at all. Bleeding the hydraulic (HSMO) systen seems to be nearly impossible as very low (if any at all)...

Hi! The real cure for this is to replace the hydraulic shocks. Yes the there is no leak but when the shocks is faulty it fails to give the desired ride height. Once the hydraulic is replaced you'll be good. Hope this helps and thank you for using FixYa!

4020 john deere compact diesel. Lost hydraulics and do not know how to check fluid level. Worked good and just quit. Can not see any leaks??

I doubt that it is the fluid's been a few years... but I seem to remember there being a couple at the front of the motor that ran the hydralic pump...I am wondering if your problem is not there...tthe hydralic pump sits under the fuel tank at the front of the tractor... check there to see if everything is working right there...of course it could be the pump its self that has gone bad...
