How can the oil pump be replaced or overhauled on 1990 Mazda RX-7?

The oil pump is changeable or serviceable. The oil pump is RX-7, which is not interchangeable with two sets of rotor, hence take care of the parts separately. Unscrew the snap ring, invert pump and unscrew rotor assembly. Wipe all the components, verify clearance, and assemble thoroughly, making sure that all the parts fit and are secured. Lastly, pour oil into the pump and fit.
