Calibrating Special Tool 9201

TOOL

The testing gage is designed for a display
of 4.0 scale units and permits the check-
ing and calibrating of Special Tool 9201
to 4.0 scale units.

The tool must be calibrated after:

	about 100 measurements
	hard jolts or knocks
	slight damage

Calibration will not be sufficient in case
of greater damage or display deviation of
more than 2.0 scale units. These special
tools can be sent to the supplier for
repairing.

CALlBRATING

Tools Required:

Small screwdriver 1.6 x 40 x 0.4 mm
Gage 9201/2

1.	Adjust to zero point by turning the dial gage's scale ring until the needle and zero point are aligned.
2.	Insert gage 9201/2, checking for centered position of both test bearing surfaces on the sliding shoes.

3.	Proceed to same procedures for use on toothed belt, i.e. press in testing point slowly until the lock pin is felt to engage and then read the displayed value from the dial gage.

N o t e

Sliding shoes of older manufacture
might be bored offcenter. Depending on
the position of the sliding shoes there
could be different displayed values when
checking with this tool.

Consequently the measurement with a gage should be repeated with different sliding shoe positions. Find the position, where the scale value is closest to the 4.0 adjusting value. Mark sliding shoe (e.g. with paint or an electric inscriber) and perform the calibra-tion as well as all measurements later at this position.

4.	If the display is outside of the test value of 4.0 +- 0.3 scale values, readjust the gage dial. This is done by turning the calibration screw with a small screwdriver until the specified value of 4.0 scale units is reached. In so doing the gage 9201/2 remains between the test sensor of the tester.

5. Recheck after finishing calibration.
