Description
-
All dimensions indicated in the figures are actual.

When using a tracking gauge, adjust both pointers to equal length. Then check the pointers and gauge itself to make sure there is no free play.
-
When a measuring tape is used, check to be sure there is no elongation, twisting or bending.
-
Measurements should be taken at the center of the mounting holes.
-
An asterisk (*) following the value at the measuring point indicates that the measuring point on the other side is symmetrically the same value.
