Setting the Legs for the A-514GS (Using Small and Medium Bore Adapters)
Example: (see Figure 7)
1. To measure a 6 in. bore, each leg must be set to 3 in.
2. Set the caliper to read 3.000 in.
3. Twist the locking nut on the caliper so it does not slide, then insert
the caliper inside the hub on the leg setting fixture.
4. Slide the leg setting gage into position and tighten the bolt using
the Allen wrench provided.
5. Slide the bore adapter over the hub and place the stop pin in the
desired hole.
6. Turn the bore adapter so it’s up against the stop pin and slide the
leg out so it rests against the leg setting ceramic plate.
7. Tighten the bolts with a 7/64 Allen wrench.
8. Remove the stop pin and turn the bore adapter one more time,
replacing the stop pin. Repeat the process for the next leg.
9. To set the remaining two legs, the bore adapter must be removed
from the hub and flipped. Secure the legs again using the same method.
Note:
The caliper is used to set the legs to the nominal bore radius. The accuracy of the caliper’s measurement of
the radius is not important since the bore adapters can handle a small range of diameter changes (typically ± .010
in. to .025 in., depending on the adapter size). The most important part of the process is to ensure the legs are the
same length, which is done with the Leg Setting Gage. So if the digital caliper has an error of .0015 in., as long as
the legs are set to the same length using the Leg Setting Gage, the bore adapter will self-center to .0005 in. (0.0127
mm) or better.
