Replace the Hydraulic Tank Breather
Cap
We require that this procedure be performed
every 500 hours or semi-annually, whichever
comes first.
The hydraulic tank is a vented-type tank. The
breather cap has an internal air filter that can
become clogged or, over time, can deteriorate.
If the breather cap is faulty or improperly
installed, impurities can enter the hydraulic
system which may cause component damage.
Extremely dirty conditions may require that the
cap be inspected more often.
1 Remove and discard the hydraulic tank
breather cap.
2 Install a new cap onto the tank.
