SOURCE: Our 2001 Dodge Caravan seems to be leaking oil around drive shaft

Yes it's a bad seal and most likely the side bearing to the trans axle is bad too. Once the bearing has play, it vibrates and causes the oil to leak though the seal. Note: if one side went bad the other side is soon to follow since they have the same amount of miles on them. Might as well change both side. Good luck and hope this helps. Keep an eye on the transmission fluid level, don't want to burn out the transmission.

SOURCE: oil leak after radiator change

The radiator has a transmission and engine oil cooler lines to it too. One of the oil lines are leaking, if you know which one that's have the battle. I believe the transmission line is on the passenger sides and the oil cooler line is on the drivers side. Look at where the lines connect to the radiator and see if there is signs of the leak. You may need to spray it down with brake cleaner if you not sure if it's a new leak or old leak from the accident. Good luck and hope this helps. And what do you mean by rear case gasket?? You mean the gasket that connects the transmission to the transfer case, or the rear O ring yoke gasket.

I have a 345 OMC mustang skid steer. deutz 2cyl diesel engine it is leaking hyd oil from under bottom of machine not on rims or tires what could be leaking


Not a CAR...

Skid Steers... like yours: we call bob-cats here (USA)...

EASIEST & most common are cracked & loose hoses.

You have a serious hydraulic pump & piston system on all the configurations I've been able to pull.

Any damaged SEAL EVERYWHERE in that circuit
is going to be hydraulic oil...

Crank-case, transmission case... (etc.).

What you are going to have to do is pressure clean the wettest areas... wipe them down... and make your EYES & BRAIN take a look around for the most severe leak...

Fix it... and repeat the process until you
have things nice, tight and dry...

On a case 580k 4x4 backhoe is 4th gear set up different then 1st 2nd 3rd tractor won't move in lower gears made no noises or grinding .


Hi Bill:
I'd check with my local Case dealer. We have several pieces of Case equipment with hydostatic drives.
If I remember correctly, high gear on a standard transmission is a 1:1 ratio in that the power is on a straight through shaft.
My suspicion would be that a shifter link ay have become dis-connected.
Here's a link that may assist.

Case 580k backhoe. Why do none of the levers to the boom work?


some hydraulic units use a flow rate valve in the bottom of a ram to stop the operation in the event of a hose failure
it effectively locks the oil in the ram to stop what is raised from free falling and becoming dangerous
Talk with the service dealer to see if you have such a valve and how to release it after repairs are carried out

Cat 426 backhoe swing very erratic when fist start and stop


It sounds like there may be a bit of air in the hydraulic system. You probably have a seal leaking. Be sure the oil resivore is full.

THIS PROBLEM IS CAUSED BY LEAKING PUMP SEALS AND THE RESULTING LOSS OF HYDRAULIC PRESSURE TO THE FORWARD CLUTCHS, THE TRANSMISSION WILL NEED TO BE OVEREHAULED TO CORRECT THIS.

2004 holdern rodeo v6 clutch went to the floor was working all good before


The problem could come from the clutch master cylinder or the slave cylinder. The cause could be external or internal.

First check the fluid level in the reservoir. The reservoir could be independent of the brake system or using the same.

If the level is too low, air may have entered in the line and the hydraulic compression is affected. So first, adjust the level in the reservoir using recommended oil. (normally brake oil is ok).

Check for any oil leak starting from the clutch pedal following hydraulic circuit up to the transmission.
Your vehicule should have two clutch cylinders: the master and the slave.
The master cylinder is operated by your clutch pedal, it's located under the dash, fixed to the firewall and connected to the hydraulic line on the other side of the firewall. Check for any leak on the carpet, under the carpet and near the hydraulic connection. Pumping the pedal making that verification could help to detect leak. Then follow the hydraulic line going to the slave cylinder attached to the transmission making a visual inspection for leaks.
If for any reason some air entered the circuit, the line could be purged from air bleeding the slave cyclinder as you do bleeding brake component.
If there is no air, no leak detected then it's probably an internal problem that you can't see. Remove the cap from the reservoir, depress the pedal. If the oil is moving in the reservoir then the master slave is probably bad otherwise I would suspect the slave.
I'm not an Isuzu technician.
Some other Gurus could complement or correct my saying.
Hope it will help

Leaking brake fluid now my clutch not working !!! help


Are you sure it was brake fluid leaking? If you were leaking transmission fluid then that could cause some of the mechanical workings to stall, in turn causing the clutch to freeze-up. The other (more likely) problem is that you were leaking hydraulic fluid for the hydraulic clutch.

It sounds like you will probably have a hydraulic clutch, and fluid was leaking. If you accidentally topped-up the hydraulic fluid for the clutch with brake fluid, that would be an interesting scenario... not sure how the mis-match would work out. If the hydraulic clutch fluid is simply low, you can flush it out, put new fluid in there and get it to a dealer to repair the clutch

Power streeing oil leeking under from car


Your Camry uses ATF ( Automatic Transmission Fluid). Your going to have to get the leak repaired, common cause is the high pressure hose is leaking and soon it will fail 100% and your going to lose your power steering. Worst is the ATF is flammable and if it hits a hot spot like the exhaust manifold, it will catch fire. Good luck and hope this helps, and don't let the fluid get too low. Low fluid in your steering pump will cause damage.
