The motor case has a cylindrical sidewall which receives and centers the dividerlike gearcase pressed into the motor case. The cover is centered by and seats on the motor case which is staked to retain the cover without transfer of staking pressures to the gearcase. Since the motor case centers the gear case and the cover, concentricity is readily attained and shafts journaled in the parts are assured alignment.
