Adjusting The Roll Timing - MacDon R85 Operator's Manual

6.4.2 Adjusting the 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 gauge. The
rolls will automatically adjust to the correct timing.
This will provide for a roll gap of 0.43 in. (11 mm) and
a roll timing setting of 0.16 in. (4 mm).
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.
