ELEMENT DISASSEMBLED FROM COVER7. Install element and cover. Tighten all bolts.8. Install the drain plug.Clean Marine Gear Oil Strainer
1. Remove the strainer cover.
REMOVING STRAINER COVER2. Remove the spring washer, strainer and magnetic screen tube.
REMOVING STRAINER AND MAGNETIC SCREEN TUBE3. Wash the strainer and magnetic screen tube in clean diesel fuel or kerosene.If a magnet is broken, install the new magnet properly; the N poles and S poles of the magnets are adjacent to each other so that they repel instead of attract: S - N, N - S, S - N.4. Inspect the strainer, and the seal in the cover for damage. Obtain new parts if necessary.5. Install the magnetic core tube, strainer, spring washer, seal and cover.Filling The Marine Gear Lube System
1. Install the marine gear drain plug, or close the sump pump valve on the oil line to the marine gear.
Be sure both valves (one to the marine gear and one to the engine oil pan) are closed. Otherwise, a transfer of oil may occur during operation and damage could result.
2. Fill the marine gear to the FULL mark on the oil level gauge. Refer to the Lubrication and Maintenance Chart for proper oil to use.Cleaning The Breather
