Is the hydraulic control valve on a bobcat leaking?

A friend of mine has a bobcat 763 C-series and is leaking hydraulic oil from what I think the service manual calls the hydraulic control valve (pages 79-104). I put a good 5 gallons of hydraulic oil before the dipstick could see any. Attached some pictures of where I see the leak.

When to release pressure before disconnecting Bobcat hydraulic coupler?

When releasing pressure before disconnecting Bobcat auxiliary hydraulic couplers, most Bobcats will have a pressure disconnect that releases pressure if you push in on it before disconnecting. There may be two of these, one top and bottom, be sure to press in on both of them to release pressure before disconnection.

What should you do if hydraulic fluid leaks?

1) Do not check for leaks with your hands – hydraulic fluid can reach high temps in the range of 300°F or more which will cause serious burns if it comes in contact with your skin.

The manual says to pump it out of the reservoir tank, however the specs say the the system holds 8.5 gallons and the reservoir holds 4.8 gallons so by doing this I would only remove around a third of the fluid. Is there some easy way to get more of the fluid out so that I replace more of it?

Can you change hydraulic oil on a 2001 Bobcat?

Click to expand… All the joking aside, we have indeed had two separate failures on the 2001 773 that effectively “drained” much of the older hydraulic oil. It’s great fun changing a main drive hose out in the field. (Willie59 always works in an climate-controlled shop.

Do you need a hose protector for a bobcat?

When I once went to buy a new hose–it was a cheap to buy the Bobcat hose as to get one made that particular day–the parts person mentioned the “hose protector” kits. Bobcat has some hard plastic pieces that zip-tie to the hoses in those places where they tend to rub.

Bobcat 773, just like all 700-series skid steer loaders, comes with a 4-cylinder Kubota diesel engine. At 46 horsepower, it is more powerful than the 40-hp 753 and shares similar power with the 763 models.

What should I do if my Bobcat loader is not running?

Do not overfill the reservoir; hydraulics work best with the exact amount of fluid in the system. Check the hydraulic fuel filter. If it’s clogged and fluid can’t flow freely, power to the loader will be reduced. Be sure the hydraulic pump (located in front of the engine) is operating to specifications.

Where is the hydraulic pump on a Bobcat loader?

What’s the code for a bobcat lift tilt?

I was just working on trying to figure ours out. The code it is posting is 32-50 (bad ground to the tilt actuator). I just looked over all the wires in the harness going from the joystick to the actuator for loose wires or wires with rubbed open spots, but couldn’t find anything.

Is there hydraulic problem on bobcat 328 excavator?

All of the other hydraulics are very strong. Machine runs great and seems to be making rated power. All filters are new and the hydraulic oil was recently changed (1000 hour service). All OEM parts are being used.

Is the hydraulic oil on my Bobcat good?

Why does my skid steer have a hydraulic problem?

If no damaged is seen, check the hydraulic filter for metal. If the oil is contaminated, the relief valves could be stuck in an open condition allowing the cylinders to leak down. It is not common to have all the reliefs to start leaking at the same time. If one relief got trash in it, only one circuit will be affected.

What’s the biggest problem with a bobcat 963?

He has S300’s now and says the 963’s pushed more but the S300’s are much better on fuel and stack higher. He has 10′ plows on them. You could put a 12′ pusher on it but would probably be better off with a 10’er. The biggest problem with a skid is the short wheelbase can cause traction issues.

What is the fault code for a Bobcat skid steer loader?

LOADER Button is pressed. Seat Bar is down. Seat Bar is up. Lift and tilt functions will not operate. Seat Bar sensor circuit shorted to battery voltage*. Seat Bar is down. Seat Bar is up.

The biggest problem with a skid is the short wheelbase can cause traction issues. They are also all single speed correct? My friend at the bobcat dealer said they were fuel guzzler’s to.

Is the bobcat lift tilt actuator bad?

Based on the post located here: http://www.skidsteerforum.com/DesktopDefault.aspx?tabid=54&frmView=ShowPost&PostID=20221 , I switched the wires to see what would happen. The code switched from 32-50 (tilt actuator short to ground) to 32-49 (lift actuator short to ground), so I guess supports the idea that the actuator is bad.

Why is my Bobcat 763 not lifting snow?

I have am using a Bobcat 763 to move snow. We used it all day yesterday and not problem and today it will not lift. It moves forward just no lifting of the bucket. What could be the problem?

Is the Witch solenoid on a bobocat 763?

It is a year 2000 I think it has the high flow option. All the lights come on when the handle is down. It does have the tilt function. We can not push the pedals in. We think the lock is not disengaging after we push the green button. Witch solenoid is it?

What are the safety switches on a bobcat?

Ours has two switches — one is a weight in the seat switch and the other is the seatbelt. When ours is locked up, you have to unlatch and re-latch the seatbelt, with some authority, and all is well again. Can’t speak to your green lights or exactly what safety switches a Bobcat has.

What is hydraulic solenoid on bobcat 773 C series?

Why is the lift light not flashing on my Bobcat 773?

If the lift/tilt is not lit up at all on the BICS controller the lift/tilt functions won’t work. If the lift/tilt light is flashing it’s indicating a fault. Since all the other LED lights are lit up on the BICS controller, only one not lit up is the lift/tilt LED and it’s not flashing either.

Why does the tilt and raise on my Bobcat not work?

The bobcat runs fine and drives fine but the tilt and raise will not work. Its like it is not disengaging. The bar that you pull down is unlocking the pedals.
