Prepare the new elements by wetting the O ring on each element
using hydraulic fluid.
Carefully insert the new filter elements onto the element mount by
rotating them slightly while applying pressure to the element.
Do not use excessive force or a hammer, etc.
Clean the sealing surfaces on the housing.
Check the O ring for visible signs of damage and, if necessary,
replace it.
Wet the O ring with hydraulic fluid and insert it.
Clean the sealing surfaces on the cover. Swivel the cover above
the filter housing and center it. Lower the cover onto the filter
housing by turning the handwheel in a counterclockwise direction.
Insert/re-engage all the clasp bolts on the cover.
Tighten the clasp bolts using a size 24 mm wrench. Tighten
the bolts opposite of one another. Apply a tightening torque
of a maximum of 85 Nm.
