CHAIN & IDLER SPROCKET ADJUSTMENT
Excessive chain slop or play may develop after using system for some time. We have incorporated
in a chain adjustment to keep chain slop or play at a minimum.
Please review drawings shown for more detailed information.
To adjust system:
1. Remove the chain cover (Cover not shown on picture above). Position your array where it might
be slightly out of balance so to allow the chain slop to gather between the adjustment idler sprocket
and the large drive sprocket. Loosen the 1/2-13 x Locking nut on the adjustment sprocket slightly.
2. Use a 9/16” socket wrench to turn adjustment bolt.
3. Clockwise rotation of the adjustment bolt will tighten the chain. Adjust the chain to 1/8” of slop or
play. Over tighting the chain can put excessive tension on the idlers and gear box drive shaft.
4. Counter clockwise rotation of the adjustment bolt will loosen the chain.
Note: Over tighting the chain can put excessive tension on the idlers and gear box drive
shaft. A loose chain can allow elevation axis system movement
5.Tighten locking bolts and nuts testsystem. Look for consistent chain tension throughout your sys-
tem movement.
6. After test tighten all hardware and replace cover.
