Abstract
The implement linkage of a work machine comprises at least one oil dilled pin joint. During operation of the linkage, pressure can build up in the pin joint, thus causing damage to the pin joint. It is desirable to vent this pressure without allowing oil to escape from the pin joint. It is also desirable to measure the level of the oil in the pin joint. A combination relief vent and dipstick apparatus which allows both these tasks to be accomplished with one apparatus is disclosed herein.
