  The radial flux of toroidal angular momentum is needed to determine tokamak
intrinsic rotation profiles. Its computation requires knowledge of the
gyrokinetic distribution functions and turbulent electrostatic potential to
second-order in $\epsilon = \rho/L$, where $\rho$ is the ion Larmor radius and
$L$ is the variation length of the magnetic field. In this article, a complete
set of equations to calculate the radial transport of toroidal angular momentum
in any tokamak is presented. In particular, the $O(\epsilon^2)$ equations for
the turbulent components of the distribution functions and electrostatic
potential are given for the first time without assuming that the poloidal
magnetic field over the magnetic field strength is small.
