Figure 5.52: Auger Drive
4. Rotate the auger (A) by hand in reverse direction, until it
cannot turn anymore.
5. Mark a line (B) across the drum and cover.
Figure 5.53: Auger Drive
6. Rotate the auger (A) by hand, in forward direction, until
it cannot turn anymore and mark a line (C) across the
drum and cover.
7. Measure the distance between the two lines (B)
and (C).
For a new chain:
• If the difference between (B) and (C) is 1–4mm
(0.04–0.16 in.), no adjustment is required.
• If the difference between (B) and (C) is greater than
4 mm (0.16 in.), the auger drive chain tension needs
adjusting. Refer to 5.7.3 Adjusting Auger Drive
Chain Tension, page 423.
For a used chain:
• If the difference between (B) and (C) is 3–8mm
(0.12–0.31 in.), no adjustment is required.
• If the difference between (B) and (C) is greater than
8 mm (0.31 in.), the auger drive chain tension needs
adjusting. Refer to 5.7.3 Adjusting Auger Drive
Chain Tension, page 423.
• If the difference between (B) and (C) is less than
3 mm (0.12 in.), the auger drive chain needs
adjusting. Refer to 5.7.3 Adjusting Auger Drive
Chain Tension, page 423.
