Large CIM motor pulley size/series?

Does anyone know the EXACT series and size pulley that is on the large CIM motor? Last year someone posted that the motor came with a pulley sized for a GT PowerGrip belt with a 3 mm pitch and 15 mm width.

I would like to use the motor as designed to drive a timing/synchronous belt and use the tensioner as well.

Thanks in advance.

From last year: this post

my suggestion would be to buy the appropriate gear for the motor and switch gears.
