Return Line Filter Element

OTE
:
While every effort is made at the Labrie factory to ensure clean hydraulic systems, it should be
noted that most hydraulic system manufacturers recommend the filter be replaced after a
break-in period. Labrie’s recommendation is to replace this filter element after a break-in
period of 50
hours of operational use.
Return Line Filter Element Replacement Procedure
The following is the procedure to replace the return line filter element:
1.
SWITCH OFF the hydraulic system. Refer to “Lockout/Tagout Procedure” on page 20.
Keep tools, working area and equipment clean. A pan will be required to collect a small amount of
oil lost as the element is removed.
2.
SLOWLY remove the hydraulic tank cap (see Figure 3-7).
SLOW turning will RELEASE system pressure.
3.
REMOVE the filter head cover bolts (four) [see Figure 3-8].
4.
REMOVE the element by the handle.
ROTATING during removal will help release suction.
5.
INSPECT o-rings and housing for damage. REPLACE as necessary.
6.
MOISTEN the filter housing and head cover sealing surfaces with oil.
7.
PLACE the new filter element into housing.
8.
REPLACE the filter head cover and PUT all 4 bolts back in.
9.
PUT BACK the tank cap into place.
10.
OPERATE the hydraulic system and CHECK for leaks.
