While holding end play gauge, rotate center screw until gauge locks into converter hub. DO NOT overtighten. Assemble remainder of special tools, as shown, onto torque converter. See Fig 1.
  2. Adjust Lug Attachment (J-5959-7) or equivalent, so Dial Indicator (J-5959-1) or equivalent, firmly contacts top of end play gauge. Set dial indicator to zero and lift end play gauge upward as far as possible. Read dial indicator and note results.
