MAINTENANCE AND SERVICING
Lubricating Auger Drive Chain
Lubricate auger drive chain every 100 hours. This can be
done with the adapter attached to the combine, but is easier
if the adapter is detached.
To lubricate the auger drive chain, follow these steps:
1. The auger drive cover consists of an upper and a lower
half.
Only the upper half needs to be removed to
grease the chain. Remove six bolts (A), securing the
upper half (C).
2. Loosen two bolts (B) at the rear of the cover.
3. Rotate upper half (C) forward to remove.
