Chain Slack
Initially check the drive chains after the first 10 hours of
drill use. Thereafter, check the chains every 100 hours.
Hub Chain
Refer to Figure 82
This chain connects the hub sprocket weldment to a
sprocket on the main drive shaft
at the left rear cart
wheel.
Check chain tension. Chain should have
1 ⁄
8 inch
(3 mm) slack. To adjust, loosen the bolts holding the
main-shaft bearings and slide the main shaft. Retighten
bolts.
Note: If you make any adjustments to the hub chain,
check tension on the chain from the main shaft to
clutch shaft (next item, not shown in Figure 82).
Clutch Input Chain
Refer to Figure 83 and Figure 84
This chain
connects a driving sprocket on the main
drive shaft to a driven sprocket on the clutch
jackshaft above the meter gearboxes.
Check that both driving and driven sprockets are aligned
(in the same plane of rotation) and that the chain is not
skewed. If not, loosen the set screws holding one or both
drive sprockets in place and move them until they are
aligned. Re-tighten the set screws.
Refer to Figure 84 and Figure 83
Check chain tension. Lower span should have
1 ⁄
2 inch
(13 mm) slack at the midpoint. To tighten, loosen idler
bolts
and adjust idlers. Do not adjust main shaft
bolts except to keep main shaft parallel to wheel
spindle if significant adjustment was necessary on hub
chain.
