Busch Major Repair Kit with GX Vanes – 0040 B part# BMK006

We put together every single part you need. No running around looking for missing pieces. Here is what you get :

The Heart – GX Vanes (3 pieces)
These are the most important parts of your pump. The GX vanes are made from a tough G11 fiberglass material . They are strong and last a long time. They do not soak up moisture like some other materials .

The Seals – Shaft Seals (2 pieces)
These stop oil from leaking out where the pump shaft comes out. Both are made of Viton rubber. Viton handles high heat and chemicals very well .
