Adjusting the Sliding Load Pin Depth
The sliding loads in this kit have a setback mechanism that allows the pin depth to be set to any
desired value. The pin depth of the sliding load is preset at the factory. The pin depth should
not have to be reset each time the sliding load is used, but it should be checked before each
use.
If the pin depth is outside the
observed limits listed in Table 2-2 on page 2-4 , use the following
procedure to reset it. Always measure the sliding load pin depth before attaching it to any
connector.
This procedure assumes that you were directed here from
“Gaging the Sliding Loads” on
page 3-12 . If not, perform the steps in that procedure before performing this procedure.
1. The gage should be attached to the sliding load. The sliding load should have its centering
bead installed. Refer to “Gaging the Sliding Loads” on page 3-12 if necessary.
2. With a 0.050 inch hex key, loosen the two largest hex screws by turning them 1/4 turn
clockwise. Refer to Figure 3-6 .
CAUTION Do not loosen any hex screws other than the two largest hex screws pointed out
in Figure 3-6 .
3. Gently turn the center conductor pin depth adjustment knob on the sliding load until the
gage pointer reads

3.81 micrometers (

1.5 x 10
 4
inches). Refer to Figure 3-6 .
4. Tighten the two hex screws just until they are finger tight (do not overtighten).
5. Wait approximately five minutes to allow the temperature to stabilize. Do not touch either the
gage or the sliding load during this time.
6. Note the gage reading. If it is no longer within the allowable range, perform steps 2

5 again.
7. Loosen the connecting nut and remove the gage from the sliding load. If you’re gong to
store the sliding load, leave the centering bead installed. If you’re going to use the sliding
load for an electrical calibration, remove the centering bead.
NOTE
When performing pin depth measurements, use different orientations of the gage
within the connector. Averaging a minimum of three readings, each taken after a
quarter-turn rotation of the gage, reduces measurement variations that result
from the gage or the connector face not being exactly perpendicular to the center
axis.
The sliding load pin depth is now in specification and the load is ready to use. Once the sliding
load pin depth is set it rarely needs to be adjusted. However, the pin depth should be
rechecked before each use. Replace the protective plastic caps on the sliding load and gage
connectors when these devices are not in use.
