ASSEMBLY – Continued
1. Locate output shaft assembly (1) in a stud--driving fixture.
2. Carefully examine 10 1--14--taped holes (11) for presence of burrs, nicks and foreign material. Remove any
defects found.
3. Measure and record pitch diameter of 10 1--14 tapped holes (11).
4. Classify each stud (10) part number into groups of A and B according to stud pitch diameter ranges as shown on
stud selection chart, WP 0086 00.
NOTE
Pitch diameter data in the stud selection chart has been arranged to give a stud interference fit of
approximately 0.0033 to 0.0045 for the four studs listed. This criterion has been created for the
tapped hole pitch diameter requirement for stud that exceeds maximum tolerance specified on
the shaft drawings. Shafts falling in this category must have normal deviation approval from
quality staff office before assembly.
5. Select proper stud (10) part number and pitch diameter range from stud selection chart by matching hole pitch
diameter measurement recorded in step 3 above with tabulated values shown on chart.
