Harley's oil system goes oil tank to pump to engine to filter to tank since there is no plug in the case, after draining the oil I put a pan under the filter before installing the filter I put 2 qts in the tank, crank the motor and watch the oil drain into the pan until it's clean. it really works. Never run your engine dry of oil!!!!!
