5.4.6. Auger Drive Chain – Tensioning / Replacement

The proper chain tension is important to reduce premature wear of the auger drive chain
itself and the sprockets that it runs over. It is more cost-effective to maintain/replace the
chain and avoid having to replace the sprocket.

To properly tension auger drive chain (see Figure 5.12), proceed as follows:

1. Open the chain guard.

2. Loosen the bolt securing the chain idler sprocket enough to allow it to slide into the

adjustment slot.

Figure 5.12 Auger Drive Chain Tension

3. Apply pressure down on the idler against the chain until there is approximately 3/4”

(19 mm) deflection of the chain in the middle of the span between the idler and the
top driving sprocket (as shown by arrow in Figure 5.12).

4. Tighten the idler adjustment bolt.

5. Recheck the deflection of the auger drive chain.

6. Close and latch the chain guard.

The auger drive chain may need to be replaced if the chain is stretched or worn exces-
sively and can no longer be tensioned properly.

To replace the auger drive chain (see Figure 5.13), proceed as follows:

a. Open the lower chain guard.

b. Remove the chain connector link and remove the auger drive chain from the

sprockets.

c. Before installing a new chain, use a straight edge to ensure that all sprockets are

properly aligned; adjust as necessary.

d. Install the new chain (95 chain links) over the sprockets; join with a new connector

link.

e. Set the chain tension as described above.
