I read the other thread on the hydraulic fluid leaking into the bottom but I cleaned mine out and ran it with the cab up and could see no leak at all. It appears that it only leaks when I lift the bucket but I don't know how to do that when the cab is up?? It's a pretty serious leak. There is oil on the center between the foot pedals but it's always been there even when the machine wasn't leaking at all. It has a very minimal leak when tilted and I'll replace that hose but this leak is more than a gallon when I run it for perhaps 30 minutes. This machine had a serious leak when I got it that continued to leak from the bottom when it sat unused. That leak just stopped spontaneously and I was never able to figure out what caused it. Now I have this leak and there was some air in oil but not now. I have the manual but have no idea where to start and I need the machine to feed farm animals so need to get it fixed fast. Thanks so much for the help and any suggestions as to how to fix it as quickly and easily as possible.

If it is leaking into the chain case from the hyro it is the seal behind the drive motor best to do both sidesYes, Right side only, leaks only when moving the lift arm, not when engine is running and not when bucket is being tilted
Where can I buy just this seal. So far all I've found are kits that are $160 bucks. GASPIf it is leaking into the chain case from the hyro it is the seal behind the drive motor best to do both sides

Or pull the seals and take them to a local shop to match up on your way home stop by lowes and get a pvc threaded adapter that matches the seal with a screw in square plug to set the sealI think that price is fo the drive motor and the case seal is not in there I paid 16 bucks per seal from bobcat for my 743 you will orings and maybe quad rings
If we are talking ride side as when you are sitting in the unit, I would say the control vavle needs to be resealed. Any number of fittings or lines could be leaking also. The gear pump if it is aluminum sometimes like to crack where the outlet fitting attaches.Or pull the seals and take them to a local shop to match up on your way home stop by lowes and get a pvc threaded adapter that matches the seal with a screw in square plug to set the seal
Drained 12 gallons excess from chain case. Pretty sure the motor seals are bad BUT that may not be the only thing so getting ready to pull the first motor. The lug nuts had been painted so were really hard to remove. Had to use a torch on one. Also had to get some bigger jack stands as my live oak logs were just too heavy to move to the garage. Thanks so much for the help. The manual is a bit of an overload to say the least.If we are talking ride side as when you are sitting in the unit, I would say the control vavle needs to be resealed.

Depending on of the backup rings are ok in the drive motors or not.Drained 12 gallons excess from chain case.

My best recommendation is if you want to do the drive motors, pull them apart then see if the plastic backup rings are bad or not. If they are ok, take the Orings to a hydraulic seal shop and get them matched. I paid about $5 for two sets. If the backup rings are bad, you need a kit, loader parts source have them cheaper than the dealer do.
Now, if oil is moving into the chain case, that is not from the drive motor seals as such, there is a seal on the reduction box that keeps the oil in the motor, but if it goes bad, it goes into the chain case. The drive motors have an open end, so no shaft seal.
Just wrote a long detailed response and got dumped from the site and lost it. To be brief it was a hose. It is fixed. Thanks so much for the help. It was invaluable. Better post this before I lose this one too.Depending on of the backup rings are ok in the drive motors or not.

Lucky man good jobJust wrote a long detailed response and got dumped from the site and lost it. To be brief it was a hose. It is fixed. Thanks so much for the help. It was invaluable. Better post this before I lose this one too.
How long does one have to write and post a reply before getting dumped? The leak was from above the hydraulic motor from a dead end hose used to pressure test I assume. Everything was cleaned thoroughly before it could be seen causing a stream of oil from above. Luckily I have a small contortionist friend who did the cleaning and the removal and installation of the new hose and tightened several hoses. So far so good. Thanks again so much!Just wrote a long detailed response and got dumped from the site and lost it. To be brief it was a hose. It is fixed. Thanks so much for the help. It was invaluable.

He wrapped a small towel over what looked like a suspicious place and put the cab down, raised and lowered the bucket, raised the cab and sure enough the towel was soaked from inside. He was able to rotate the metal elbow at the bottom of the hose enough to get an open end wrench on it, break it loose and finally remove it without having to take off all the other hoses in the way so got lucky on that one. The cleaning was the key to finding the leak.How long does one have to write and post a reply before getting dumped?

Every bobcat owner needs a very very small contortionist friend who doesn't mind getting very dirty. Until we meet again I bid you all adieu.He wrapped a small towel over what looked like a suspicious place and put the cab down, raised and lowered the bucket, raised the cab and sure enough the towel was soaked from inside.
