(5) Remove TI from C-clamp.
b. Adjustments
(1) Remove micrometer from (A1) and C-clamp (B2) from TI.
(2) Loosen the socket head adjusting screw (1, fig. 1), at the back of the slider, four
turns.
(3) Position the TI on its back.
(4) Remove the socket head screw at the bottom center of the TI.
(5) Remove the shim(s) between the bottom of the gauge assembly and the frame.
(6) Remove the gauge assembly from the frame. Use care not to lose the loading
ball that is between the pressure button of the gauge assembly and the end of the slider
(7) Clean the mating surfaces of the gauge assembly and the frame with a soft
cloth.
(8) Adjust the shim thickness to achieve a correct micrometer frame reading as
follows:
(a) If the micrometer frame reads low, remove shim(s) as required.
NOTE
A .001 inch shim will move the gauge reading approximately
10 lbs. The shim utilized in the TI is laminated from .002 inch
shim stock. The thickness can be reduced by removing one or
more .002 inch laminates or by sanding the shim, using 400
grade sandpaper.
(b) If the micrometer frame reads high, add shim(s) as required
(9) Install the loading ball in the slider, the gage and the shims into the TI frame.
Insure that the loading ball is seated in socket of gauge assembly. Install socket head cap
screw and torque to 105 inch/pounds.
(10) Repeat the performance checks of 8a above.
9. Final Procedure
a. Deenergize and disconnect all equipment.
b. In accordance with TM 38-750, annotate and affix DA Label 80 (US Army
Calibrated Instrument). When the TI receives limited or special calibration, annotate and
affix DA label 163 (US Army Limited or Special Calibration). When the TI cannot be
adjusted within tolerance, annotate and affix DA Form 2417 (US Army Calibration System
Rejected Instrument.
