Collecting Shaft Fork Data

A. Use the outer straight edge of the vertical carriage support at one side (left or right) as a common datum
to measure from.

B. Measure horizontally across to the front of the shaft that supports the fork.

C. Measure the diameter of the shaft. (Preferably away from the center of the shaft as it may be worn.)

D. Measure horizontally across to front face of the lower carriage bar.

E. Measure vertically from the underside of the shaft to the top of the lower carriage bar.

F. First check for wear on the underside of blade just in front of the outside heel, if there is no wear,lower the forks onto a flat smooth surface and measure from that surface up to the underside of
the shaft to get a vertical dimension.

G. Measure the I.D. and O.D. of the tube. Check if the tube has a bushing in the I.D.

H. Check for any other restrictions for the tube that can limit the tube O.D. such as a top carriage cross-member.

J. Measure the carriage bar height.

K. Use the TUBE LOCATION formula above to establish; INSET, OFFSET or INLINE value.
