      HINT: 

      By applying MP grease, the wobble within the clutch drum oil seal ring installation groove will be eliminated, preventing damage to the clutch drum oil seal ring at the time of front oil pump assembly installation.

    2. Coat 4 new clutch drum oil seal rings with Toyota Genuine ATF WS and install them to the front oil pump assembly.
      NOTE:

      While making the spread of the opening of the clutch drum oil seal ring as small as possible, install it to the front oil pump assembly.

      If the ring opening is spread, briefly hold it closed with your fingers to return it to its original condition.
