Hello All,

I noticed a oil spot on the garage floor after the tractor was parked overnight. After looking closely I noticed it was coming from one or two of the FEL hydro connectors (took off the FEL to do some cutting with the MMM). This also happens with my rear fittings. When I remove the plugs for the MMM lift, it will drip for days.

Question is: Does anyone ever notice that when they disconnect either the FEL or the rear fittings that they drip for a day or two afterwards?

I do put the dust caps in. To bad these do not work like corks /forums/images/graemlins/wink.gif

Thanks,

Brandon

I take my FEL off and on way to much. Like you say, they do drip as soon as your pull the fittings apart, but I havent noticed any additional leaking when the stops are put in overnight or anything.

The connectors consist of a female and male part. I don't understand what the 'plug' is that you mention. Is it the female part, that is with the tractor, that 'leaks for days'? And is the 'leak' a drip or a flow?

If a drip, I would take a clean cloth or paper shop towel and dry off the female connector a few minutes after disconnecting. Then I would try to see where the 'drip' comes from and how often it 'drips'. Be sure it isn't the small bit of initial flow after disconnecting that is running down on the tractor, that later makes its way to drip on the floor. A few shop towel tests will indicate what is happening.

Hopefully a remedy can be found with some more information from your end. /forums/images/graemlins/wink.gif

I don't get any amount of oil out of my connectors after disconnecting. I would be looking for a fix if their was anything more than an occasional drip. There may be an '0' ring that has torn or unseated and the offending connector could be isolated with some detective work.
