Roll Timing
For proper conditioning, the rolls must be timed
with each steel bar on one roll centered between
two bars of the other roll as shown.
WARNING: To avoid bodily injury or
death from unexpected start-up or
fall of raised machine; stop engine,
remove key and engage lift cylinder
stops before going under machine to
examine roll timing, or for any
reason.
Examine roll timing along the length of the rolls
and adjust to desired position as follows:
1. Adjust roll drive chain tension (previous page).
2. Loosen two bolts (A) in slots
of yoke plate on
either upper or lower roll universal shaft.
3. Remove bolt (B) from one of the series of holes
in yoke plate.
4. Turn rolls to achieve best timing.
5. When roll timing is satisfactory, align any of the
holes in yoke plate with a hole in mating plate
at drive case and install and tighten bolt (B).
Tighten bolts (A) to secure the position.
NOTE: This adjustment should be made in
conjunction with the "Roll Gap" adjustment,
