Dial Indicator Assembly and Set Up
The dial indicator set consist of three major parts:
1.
Vise Grip Pliers w/Swivel Joint
2.
Flex Bar Assembly
3.
Indicator Assembly
1.
Begin assembly by screwing the flex bar into the
swivel joint located on the vise grip pliers and tighten
securely.
2.
Insert the indicator into the indicator clamp and
secure in place using the clamp screw.
Note:
Always loosen the indicator clamp screw
when repositioning the indicator, otherwise the indi-
cator will be damaged.
3.
At the end of the flex bar opposite the indicator
clamp you will observe a lever with a red plastic cover.
This is the cam locking lever used to make the flex bar
ridged when making a dial indicator runout measure-
ment.
Note:
To increase the tension on the flex bar when
engaging the cam locking lever rotate the tension
screw located below the indicator clamp counterclock-
wise.
4.
When attaching the dial indicator assembly to a
vehicle for measuring runout, it may be necessary to
adjust the swivel bolt slightly to maintain indicator
position. This adjustment is only required periodically.
