Adjusting Top Idler Roll Drive Chain

To ensure that all slack is removed from chain, close gate and engage PTO a few seconds. Shut off tractor engine.

Adjust tension of main drive chain (A) as follows:

1. Loosen idler lock nut (B).

2. Press idler (C) against chain so that chain deflection to (D) is about:

  • 572 and 592: 20 mm (0.8 in.)
  • 582: 10 mm (0.4 in.)

3. Tighten idler lock nut (B).

If idler touches the end of slot before the chain (A) is tightened, remove one link from drive chain.

4. Engage PTO a few seconds.

5. Check the chain deflection. Repeat adjustment if necessary.
