Part: Honda CB175 / CB200 / CB350 / CB360 / CB450 Oil Filter Nut Tool
Why You Need This: This one stumps a lot of people as Honda is pretty straight forward with how they build their motors. However, there is a special nut inside the oil filter (oil slinger) and it can only be removed with this tool. The oil filter architecture on the CB175 / CB200 / CB350 / CB360 / CB450 family of bikes is the same which means they all have the same special nut. If you are doing an engine rebuild or removing the oil filter, this tool is a must have. It uses a 3/8" drive extension to reach inside the filter cup. This oil filter tool also is used on the clutch assembly on many Hondas from the 70's as well, such as the CB750.
Installation Tip: Clean out the filter housing before attempting to remove the nut. Use a screwdriver to bend the tabs of the locking washer out of the way from the nut. Wedge a penny between the crank drive gear and the clutch gear to hold the engine in place while you remove the nut. Take note of which side was facing down for proper reassembly. Nut must be torqued to 33 to 39 ft/lbs with a torque wrench.
