Changing the belts on an AutoGate Vertical Pivot operator is easy by following the step by step procedure outlined below. As al-
ways, we are only a phone call away should you need assistance at 800-944-4283.
1. Remove the (4) Tek Screws on the Top Panel using a 5/16” nut driver, remove and set aside.
2. Remove the STIFFENER PLATE (#1) from the POISITION SENSOR bracket. This allows a space to remove belts.
3. Release the MOTOR DRIVE BELT (#2) tension by loosening the (4) 3/8” CARRIAGE BOLT nuts securing the GEAR MOTOR
bracket (#3) to the SIDE SLIDE plates (#4) with a 9/16” wrench. Now using a 9/16” wrench, back off the (2) Gear Motor
FORCING screws (#5) so that only 1” remains through the coupling nut.
4. Slide the GEAR MOTOR assembly to create slack in the belts.
5. On the center of the pulleys. Loosen the FLANGE BEARING bolts (#6) about one turn that secure the shaft bearings using a
15/16” wrench.
6. Loosen the MIDDLE FORCING screw (#7) which is applying tension on the DROP ARM/GATE DRIVE belts (#8) by using a 15/16”
wrench. This too needs to be fully loosened to allow enough room to remove the belts.
7. Remove old belts and install new belts loosely.
8. Apply snug pressure to the MOTOR DRIVE belts by using the (2) GEAR MOTOR FORCING screws. This should also snug the
DROP ARM/GATE DRIVE belts. Do not overtighten!
9. Thread the MIDDLE FORCING screw to finger tight.
10. Re-Assemble the STIFFNER PLATE to the POSITION SENSOR bracket.
11. Operate the Drop arm/gate up and down for (5) time to seat the belts.
12. Tighten the MIDDLE FORCING screw to tighten the DROP ARM/GATE DRIVE belts. Correct tightness is 10lbs. of pressure ap-
plied at the center of belts with a 1/2” defection.
13. Tighten the FLANGE BEARING bolts on the middle set of pulleys.
14. Tighten the GEAR MOTOR FORCING screw to achieve 1/4” deflection with 10lbs. of pressure applied at the center of the belts.
15. Tighten the (4) CARRIAGE bolts to secure the GEAR MOTOR bracket to the SIDE SLIDE plates.
16. Operate the Drop arm/gate up and down 5-10 times to check for proper operation.
17. Replace the Top Panel using the (4) Tek screws.
