CHAIN IDLER SPROCKET ADJUSTMENT
(See Figure 8)
INSIDE CHAINS ARE FOR TINES - OUTSIDE CHAIN ARE FOR REAR WHEELS
The chain idler sprockets (two per side, total four) can be adjusted to remove excess slack in the
chain caused by normal chain wear or stretch. Before adjusting idler sprocket position, ensure that
the chain and all sprockets have been cleaned and that the chain seats properly on the sprockets.
A build-up of dirt on the sprockets or chain can cause the chain to become too tight. Inspect all the
sprockets, bearings, and the chain for wear or damage. Inspect for sprocket wear.
TINE CHAINS - With the tine reel elevated, loosen the idler sprocket and move along the slot to
adjust to the proper tension setting. Chain should have a up and down movement of 1/2” inch
to 3/4” inch (12 mm to 19 mm). Take measurement half way along the upper half of the chain
between the tine sprocket the hydraulic motor. Retighten idler sprocket and recheck tension setting
measurement. Set both sides with the same tension.
REAR WHEEL CHAINS - With the rear tires elevated, loosen the idler sprocket and move along
the slot to adjust to the proper tension setting. Chain should have a up and down movement of 1/2”
inch to 3/4” inch (12 mm to 19 mm). Take measurement half way along the upper half of the chain
between the rear wheel sprocket the hydraulic motor. Retighten idler sprocket and recheck tension
setting measurement. Set both sides with the same tension.
