Adjusting the Dump Valve Udder
Udder refers to the amount that the dump valve bulges out
below the bucket shell, when the bucket is full. Dump valve
udder adjustment has a significant effect on the valve seal
between the fabric dump valve itself and the bucket shell. This
adjustment is carried out by lengthening or shortening the
tripline adjustment chain.
Ninety percent of the dump valve seal is produced by the
stainless steel bolts passing through the neoprene foam and the
bucket. The balance of the sealing action is a result of the valve
“uddering” out the bottom of the bucket and compressing the
foam between the valve and the bucket.
Exposed Udder
A properly adjusted dump valve will have a maximum of 2" (50 mm) of udder. Too much udder will add to
the volume and thus the weight of the bucket. Too little udder will prevent the secondary sealing action and
will result in the valve leaking.
Adjusting the Udder via the Tripline
Each new Bambi bucket is adjusted and checked at the
factory under full fill for proper dump valve adjustment.
To adjust the udder, change the length of the tripline by
adjusting it at the tripline adjustment chain.
The method of securing the ring and riser is to secure the
adjustment chain to a shackle that is attached to the
tripline.
If a new tripline is installed, first install it at the same
point on the adjustment chain and then test the dump
valve in use. Remember to secure the adjustment
shackle with a lockwire or tie wrap first. It is impossible
to judge udder with an empty bucket on the ground.
