Installing water pump shaft collar

[miff]

I have to much water pump shaft in and out play . I have read on the fourm to install shaft collar . The collar comes with a
Plastic washer . I assume the the collar and washer go on the shaft just behind the nose on the water pump . You have the fan , going backwards towards the motor . Front casting of the pump . Then the open space . I think that is where the shaft collar goes . Washer then collar. Am I right . Miff
