Installing the Drive on Gate Post
Rev: A
1-3
Adjusting the Drive Height:
1)
Raise the operator to the correct height so that it engages the toothrack in the gate beam.
Clearance between the toothrack and spur gear should be .11” (2.7mm); an 11ga tie wire can be
used as a gauge to set the correct clearance. See Figure 1-4.
Adjusting the Spur Gear Alignment:
1)
To adjust spur gear alignment with the toothrack, loosen but DO NOT REMOVE, the
2 - ¼-20 x 2.0” retaining bolts and lock nuts on spur gear. See Figure 1-5 & 1-6.
2)
Insert 2 – ¼-20 hex bolts into the threaded holes in the taper bushing. Alternately tighten the
hex bolts to release the taper bushing. When bushing is loose remove the 2 hex bolts.
See Figure 1-7.
3)
Adjust spur gear so it is centered on the toothrack, re-tighten the 2 -¼-20 x 2.0” retaining bolts
and lock nuts on spur gear.
