What to do if the diesel tap/diesel stopcock/tank tap is dripping?
Figure 1 - Position of the diesel shut-off valve on a Zetor 2011. It is also located in a similar position on the Zetor 3011 to Zetor 6945.
Picture 2 - CZ pull cock/diesel cock usually built directly under the diesel tank. Here removed from the tank so that it can be adjusted. Theoretically, this can also be done on the tank, but it is very fiddly.
It's best to have a helper on hand who can briefly hold their finger on the screw connection on the tank while you remove and readjust the slide. Then the diesel does not have to be drained completely.
On the other hand, this would be the moment to flush the tank...
Picture 3 - if you loosen the small slotted or Phillips screw, you can easily pull out the tap slider completely. Don't worry, the small screw doesn't actually adjust anything, it just limits the way you can pull the slider and thus protects it from being pulled out accidentally.
Picture 4 - now you can loosen the locking nut on/in the handle a little and then screw in the adjusting screw a little to make the sealing element a little more bulbous. Be careful not to overdo it, otherwise the slider will be too difficult or not go in at all. In this case, unscrew the adjusting screw a little again.
The slider should be tight, not too light and not too tight. If the sealing element is still intact, the slide will be sealed again afterwards.
And if not, then you will also have to buy new stopcocks.
