A right angle drive adapter for use with an oil well vertical drive head having a drive head housing and an input shaft rotatably mounted in and extending axially outwardly of the drive head housing. The adapter comprises an adapter housing removably securable to the drive head housing in axial alignment therewith, an input shaft mounted in the adapter housing for rotation therein and for removable attachment to a rotary source of power, an output shaft mounted in the adapter housing for rotation therein at substantially a right angle to the input shaft, the output shaft having a socket for telescopically receiving and drivingly connecting to the drive head input shaft; and a gearset mounted in the housing for drivingly connecting the input'and output shafts. The adapter allows the installation of a vertical drive head and a gas engine to be used for driving the drive head before electrical power is available. When electrical power becomes available, the adaptor is removed and the gas engine is replaced by an electric motor which is connected directly to the drive head.
