Husqvarna HUV 4421-G / GXP, HUV 4421-D / DXP owner manual Remove Engine Oil Filter

Engine Oil

NOTE: An oil drip guard (1) can be used to prevent excess oil from dripping onto the engine base plate (Figure 26). Use an empty quart (one liter) container and cut the bottom off at an angle, then slide the open area of the container up and under the oil filter (2) before removal. Position the port of the plastic container so oil will be directed into the oil pan (3). A drip guard can be made by folding a piece of cardboard, thin metal, or plastic under the oil filter, forming a channel to direct the filter port oil into the drain pan.

Dispose of used oil according to the environmental laws and regulations for your area.

4.Use a clean, lint-free rag to wipe the oil filter port flange surface clean where the oil filter gasket seats.

5.To help seal the new oil filter to the oil port flange, apply a light coat of white lithium NLGI Number 2 grease (Dow Corning® BR2-Plus or equivalent) or new engine oil to the rubber seal around the outside surface of the filter before attaching it to the oil filter port (Figure 27, Page 38). Install the new oil filter (gas: P/N 603 00 00-06) (diesel: P/N 603 00 00-41) onto the engine oil filter port. See following NOTE.

NOTE: Use only oil filters designed for your engine.
