The A-514GS and A-514GL Leg-Setting Gage
The gages are used to set the A-514 Adapter legs to the correct bore
diameter. The gages are available in two sizes, depending on the
size of the bore being measured. The A-514GS is used with the
small (A-514A) or medium (A-514B) bore adapters. The A-514GL
can be used for all three adapters and must be purchased if using the
large bore adapter.
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. Iif 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.
