(1) The pump that is newly put into use; usually it needs to replace the smooth grease (oil) after 100 hours of operation; it will be replaced once every 500 hours in the future.
(2) Select smooth bearing with smooth grease; after 1500 hours of operation; replace the smooth grease; the amount of oil added may not be too much or too little; too much or too little smooth grease will cause the bearing to heat; the amount of fuel is usually grasped 1/2 to 2/3 of the bearing chamber volume is appropriate.
(3) Regarding the selection of smooth oil smooth bearings; the amount of oil should be added to the regular orientation.
(4) Containers containing smooth oil or smooth grease should be clean; usually should be sealed; there should be no dust, iron filings, etc.; avoid damage to the bearings.
(5) The motor bearing usually uses sodium-based smooth grease; this smooth grease is characterized by high temperature (125 ° C); but it is easy to dissolve in water; therefore it can not be used for the smoothness of water pump bearings.
