endplate (with wave washer and bearing) and cylinder assembly from motor module.
2. Remove Vanes (2A) qty # 5 from rotor and using degreaser clean all surfaces of rotor and endplates. Make sure not to get degreaser in
bearing or it may be damaged.
3. Oil all surfaces of new vanes (qty # 5) with ingersoll rand # 10 oil. Place them one at a time in rotor (1) slots. Make sure to match vane profile
