Adjusting Roll Timing - MacDon R85 Operator's Manual

4.4.2 Adjusting Roll Timing

Follow these steps to adjust the roll timing (if necessary):
1. Loosen four bolts (A) in slots of yoke plate (B) on upper
roll universal shaft.
2. Locate roll timing gauge (MD #150572) (B) on
frame member under the flange. Remove nut (A) to
remove gauge.
3. Position gauge (MD #150572) (A) at left end of rolls,
and manually turn the rolls to engage. The rolls will
automatically adjust to the correct timing.
This will provide for a roll gap of 11 mm (7/16 in.) and
a roll timing setting of 4 mm (3/16 in.).
4. Using the roll gap adjustment bolt, reduce the roll gap
until the roll sits lightly on the gauge.
5. Repeat procedure for right end of the conditioner.
6. Tighten bolts in slots of yoke plate to secure the upper
conditioner roll position.
7. Turn the rolls manually to release gauge.
CAUTION
To ensure gauge is not forcibly ejected from rolls
when machine is started, ensure gauge is securely
reattached to frame.
