Inspection Wear Limits
Link Support Arm
• Nominal Arm Thickness – 3.000” (from contact area to top of body)
• Minimum Arm Thickness after wear – 2.938”
Bore (measured with bodies wedged apart to remove all slack in components)
1. BDA100-238N – 2.512” (maximum localized length = 0.594)
2. BDA100-238U – 2.764” (maximum localized length = 0.648)
3. BDA100-278N – 3.013” (maximum localized length = 0.718)
4. BDA100-278U – 3.264” (maximum localized length = 0.773)
5. BDA100-312N – 3.639” (maximum localized length = 0.875)
6. BDA100-312U – 3.920” (maximum localized length = 0.937)
If localized portions of the bore are found to measure larger than the maximum bore
allowance tabulated above, the bore need not be rejected provided that all of the
following conditions are met:
a) The depth of wear, grinding, or other damage in the localized portion(s) of the
bore shall not exceed 1/8 inch (3.2 mm).
b) The surface of all localized wear, grinding, or other damage, shall be blended back
to the adjacent bore surface with a transition not less than a ratio of 3 to 1 (length
to depth).
c) After blending, the total length (measured around the bore surface) of all such
areas of localized wear, grinding, etc., including transitions to the bore surface
shall not exceed the maximum length shown above.
