Checking Stub Guard Hold-Downs - MacDon D65 Operator's Manual

Checking Stub Guard Hold-Downs

This procedure is to measure clearance between hold-downs and knife sections on single- and double-knife headers with
stub guards.
DANGER
To prevent bodily injury or death from the unexpected startup of the machine, always stop the engine and remove the
key before adjusting the machine.
1. Shut down the engine, and remove the key from the ignition.
2. Manually stroke knife to locate section under
hold-down (A).
3. Standard guard: At standard guard locations, push knife
section (B) down against guard (C) and measure clearance
between hold-down clip (A) and knife section (B) with a
feeler gauge. The clearance should be as follows:
• At hold-down tip (D): 0.1–0.4 mm (0.004–0.016 in.)
• At rear of hold-down (E): 0.1–1.0 mm (0.004–0.040 in.)
• At sheet metal hold-down (F): 0.1–0.6 mm (0.004–
0.024 in.)
4. If necessary, refer to Adjusting Stub Guard Hold-Downs,
page 152.
