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)

To measure a 6 in. bore, each leg must be set to 3 in.

Set the caliper to read 3.000 in.

Twist the locking nut on the caliper so it does not slide, then

insert the caliper inside the hub on the leg setting fixture.

Slide the leg setting gage into position and tighten the bolt

using the Allen wrench provided.

Slide the bore adapter over the hub and place the stop pin in the

desired hole.

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.

Tighten the bolts with a 7/64 Allen wrench.

Remove the stop pin and turn the bore adapter one more

time, replacing the stop pin. Repeat the process for the next

leg.

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.
