Problem
Some machines may experience loose hydraulic oil filter caps or caps with damaged O-rings and gaskets. This can result in hydraulic oil leakage at the cap.Solution
Caterpillar is aware of this problem, but a permanent fix has not yet been defined. If the hydraulic cap leaks, replace with the same part (481-6650). To replace the O-rings and gasket use the following illustration and table to identify the parts to be replaced.
