Return Filter Replacement
N
OTE
:
While every effort is made at the Labrie factory to ensure clean hydraulic systems, it should be
noted that most hydraulic system experts recommend the return 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 operation.
The procedure to replace the return filter element(s) is as follows:
1.
Turn off the vehicle. Refer to “Lockout/Tagout Procedure” on page 33.
N

: Keep tools, working area and equipment clean. A pan will be required to collect a small amount
of oil lost as the elements are removed.
2. Slowly remove the hydraulic tank filler cap. By slowly turning the threaded cap, air pressure will
be released gradually.
3. Remove the four (4) cover plate bolts and lift off the plate. Inspect the bypass valve.
4. Reach inside and remove the two elements.
5. Place the new elements into the housing
