• Minimum Arm Thickness after wear – 1.813”
Bore
1. TEA035-238N – 2.512” (maximum localized length = 0.594)
2. TEA035-238U – 2.764” (maximum localized length = 0.648)
3. TEA035-278N – 3.013” (maximum localized length = 0.718)
4. TEA035-278U – 3.264” (maximum localized length = 0.773)
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.
