ROLLS AND ROLL DRIVE (continued)

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,

detailed in Operation section.
