  16. Select the 6th main adjusting shim and then install it onto the mainshaft.
    • Calculate thickness "S" of 6th main adjusting shim by procedure below so that end play dimension between 6th main gear and mainshaft rear bearing becomes the dimension specified.

    End play: 0 - 0.1 mm (0 - 0.004 in) 

    Dimension "S" = ("S1" - "S2") + End play 

    "S": thickness of adjusting shim 

    "S2": 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 1 adjusting shim can be selected.
