Metric threading requires 5 gear changes to
achieve all of the available pitches listed on
the chart. refer to
figure 25 while reading the
instructions below.
To change gears:
1. loosen the nut below the middle gear and
rotate the bracket so the middle gear moves
away from gear F.
2. loosen the cap screw at the center of the
middle gear and slide it away from gear g.
3. gear F can be removed by loosening the cap
screw in its middle. gear g has a setscrew in
its rim. loosen this screw and pull the gear
off of the shaft.
4. replace these two gears with the gears which
will produce the desired pitch and secure with
screws provided.
5. slide the middle gear until it is in mesh with
the g gear. tighten the cap screw at the
center.
6. pivot the bracket until the middle gear is in
mesh with gear F and tighten the nut below.
