This is not just a filter change kit. This is a full rebuild kit. Becker engineers designed it to include every part that wears out over time. Here is what you get :

• A full set of vanes (3 plastic vanes) – these are the moving parts inside the pump 

• Bearings (2 ball bearings, type 6207) – for smooth rotation

• Complete gasket set – stops all oil leaks

• Coupling disc (spider coupling) – connects the motor to the pump

• Oil separating element (2 pieces) – stops oil from leaving with the air 

• Oil filter cartridge – keeps the oil clean

• Coarse separator – first stage of oil separation

• Float assembly – controls oil return

• Shaft seal rings – prevent oil leaks along the shaft

• Distance disc – for proper bearing spacing

• All O-rings and sealing rings – copper, aluminum, and viton seals for every connection
