Replacement turbine for the ZPT-PG Precision Grinder.

If you notice a decrease in performance or an unusual noise (whining/grinding), excess vibration or poor bur retention, immediately change the turbine. These are consumable components. 

Turbines will last longer if the operating pressure is kept low, and if no pressure is applied to them. Lubrication will extend the life of the turbine considerably, but the downside is that there will be oil sputter (which you may not want on your fossil). Use a high-speed dental handpiece lubricant (can be purchased elsewhere online).
