Select 6th main gear adjusting shim and then install it onto mainshaft.
- Calculate thickness "S" of 6th main gear adjusting shim following the procedure below so that end play dimension between 6th main gear and mainshaft rear bearing becomes the dimension shown below. Refer to "6TH MAIN GEAR ADJUSTING SHIM ".
  End play : Refer to "6TH MAIN GEAR ADJUSTING SHIM ".
  
  Dimension "S" = (S1 - S2) - End play
  
  S : Thickness of adjusting shim
  
  S1 : Dimension from mainshaft standard face to mainshaft rear bearing press-fit end face
  
  S2 : Dimension from mainshaft standard face to 6th main gear end face
  
  CAUTION: Only one adjusting shim can be selected.
  1. Measure dimension "S1 " and "S2 " using a height gauge (A) and pick tester (B).
  2. Install selected 6th main gear adjusting shim to mainshaft.
