NOTE: Cleaning the primary element is not rec-
ommended.
Secondary Element
NOTE: Replace the secondary element only if it is
visibly dirty or if the primary element has been
replaced three times.
Before removing the secondary element from the hous-
ing, clean out any dirt in the housing. Leave the sec-
ondary element installed during this step to prevent
debris from entering the engine intake manifold.
Remove the secondary element.
Reinstallation
IMPORTANT: NEVER use an element that is
damaged. Severe engine wear and eventual fail-
ure can result if dirt gets through a hole in the ele-
ment.
1. Check inside the housing for any damage that may
interfere with the elements.
2. Be sure that the element sealing surfaces are clean.
3. Insert the element(s), making sure that they are
seated properly.
4. Secure the end cap to the housing with the three
latches.
5. Check the hose connections and make sure they
are all clamped and tightened properly.
6. Reset the restriction indicator by pressing the reset
button.
CHANGING AXLE DIFFERENTIAL AND
PLANETARY OIL
Differential
1. Remove the three drain plugs and drain the oil.
Replace the drain plugs (see illustration).
IMPORTANT: DO NOT discharge oil onto ground.
Catch and dispose of per local waste disposal
regulations.
2. Remove the check and fill plugs. Fill the differen-
tial with oil as specified in the Lubrication chapter.
When the oil flows out the check hole, replace the
plug. Wait 10 to 15 minutes and repeat this process
until the axle is full. Repeat this procedure with the
other axle.

down. Remove the drain/fill plug and allow the oil
to drain out. Replace the plug.
IMPORTANT: DO NOT discharge oil onto ground.
Catch and dispose of per local waste disposal
regulations.
2. Re-position the hub so the oil level arrow is hori-
zontal. Fill with fresh oil as specified in the
Lubrication chapter. When the oil runs out, install
the drain/fill plug. Repeat this procedure on the
three remaining hubs.
