Vacuum pump for 2.7 diesel motor

[Pat D]

My Nissan terranos vacuum pump which is attached to the rear of the alternator is not working.Can anyone please tell me who may have exchange units in auckland or alternatively a good repairer of the same. Thanks Pat D

Normally the cause of failure is the splines on the rotor the drive the vac pump.
When the splines strip it is time for a new alternator.
