CLEANING AND CHANGING FILTERS
►
ENGINE OIL FILTER
Using a filter wrench turn the filter anti clockwise to remove it. Lightly smear the
rubber seal on the new filter with oil to ensure, turn it clockwise until the seal
contacts the base and then turn it another 2/3 turn to tighten it.
1. Close the fuel supply valve (if equipped).
2. Clean the outside of the fuel filter assembly.
Note : If the fuel filter element is mot equipped with a drain, remove cap. Remove the nylon insert in order to reduce the lever of
fuel in the fuel filter element. A reduction in the level of fuel in the fuel filter element will help prevent fuel from being
spilled when the element is removed.
Notice : Do not use a tool in order to remove the fuel filter. Attempting to remove the fuel filter with a filter wrench or a filter
strap could damage the locking ring.
3. Hold fuel filter and rotate quick release collar counterclockwise. Removed and discarded.

FUEL FILTER
The fuel filter/water separator (if equipped) is not usually supplied by Perkins.
The following test describes a typical fuel filter/water separator.
Refer to the OEM information for further information in the fuel filter/water separator.
Turn the fuel supply valve (if equipped) to the OFF position before performing this
maintenance. Place a tray under the fuel filter in order to catch any fuel that might spill.
Clean up any spilled fuel immediately.
