BALANCE SYSTEM CABLE, SPRING, AND SHEAVE REPLACEMENT
INSTRUCTIONS
NOTE: TURN POWER OFF BEFORE REPLACING BALANCE SYSTEM
COMPONENETS. WHEN REPLACING BALANCE SYSTEM COMPONENETS
ALWAYS CHECK THE SHEAVE BEARINGS, AND REPLACE IF NEEDED. MAKE
SURE THE TENSION CABLE IS IN THE GROVE OF CABLE SHEAVE WHEN
TIGHTENING THE SPRING.
1. Open access doors, and turn power off. If cable, or spring that is being replaced is on the
opposite side from access doors remove side panel on that side.
2. Open both manual bypass valves on hydraulic pump unit, (ref # 1). Manually raise barrier to
about 50 degrees. Place the safety rod thru the three brackets to secure barrier. Two brackets
welded to the frame, (ref # 2), and one bracket welded to the carriage, (ref # 3).
3. Check for paint mark on square tube under tension spring by upper spring end. If there is no
mark to indicate spring tension, make one to insure the spring is tightened to proper tension
for balance.
4. Lubricate spring tension screw. Use a 1 5/8” socket to turn tension screw nut counter
clockwise to loosen spring, and clockwise to tighten spring, (ref # 4).
5. To replace broken cable . Remove cotter pin from pin at the top of the carriage (ref # 5).
Remove flat washer, and cable. Remove cotter pin from pin on lower spring end (ref # 6)
Remove pin, and cable. Check bearings in sheaves, and route the cable under the front sheave
(ref # 7). It may be necessary to remove the front sheave to get the cable under it. If the
sheave must be removed to replace cable make note of the hole the shoulder bolt passes thru.
Place eye of cable on pin of carriage, and install flat washer, and cotter pin. Pull loose end of
cable towards spring end. Make note of how far spring end must move to reach the free end of
cable. Turn tension screw nut counter clockwise until the cable can be attached to spring end.
Install the pin thru spring end, and cable eye. Secure with cotter pin. Be sure that the safety
switch plate is aligned with safety switch when tension springs are tightened (ref # 8).Turn
tension spring nut clockwise until upper spring end reaches the mark on the square tube.
Remove safety rod, reattach position linkage, and check balance. Adjust accordingly. For
balancing instructions see page 68.
6. To replace broken spring
.
Remove cotter pin from pin on lower spring end (ref # 6). Inspect
cable for broken strands. If there are 5 broken strands per lay, or 10 over all replace cable.
Before unwinding spring refer to # 2, and 3 above. Turn tension screw nut counter clockwise
until upper spring end comes off tension screw. If your replacement spring did not come with
spring ends then you must reuse the ends from your broken spring. Start the new spring on the
tension screw, and connect the cable using pin, and secure with cotter pin. Turning the tension
screw nut clockwise watch the cable to make sure it is in the groove of the sheave. Also be
sure that the safety switch plate is aligned with safety switch (ref # 8). Tighten the spring up
to the mark on the square tube. Remove safety rod,
reattach position linkage, and check
balance. Adjust accordingly. For balancing instructions see page 43.
7. To replace sheave. Before unwinding spring refer to #2, and 3 above. Turn tension screw nut
counter clockwise until there enough slack in cable to rotate the sheave freely by hand. Make
note of the hole the shoulder bolt goes thru. Remove nylock hex nut and shoulder bolt.
Remove the sheave, and replace with new sheave. Reinstall shoulder bolt, and nylock hex nut.
Turning the tension screw nut clockwise watch the cable to make sure it is in the groove of
the sheave. Also be sure that the safety switch plate is aligned with safety switch (ref # 8).
Remove safety rod, reattach position linkage, and check balance. Adjust accordingly. For
balancing instructions see page 43.
8. After checking balance, and adjusting the balance close the manual bypass valves.
9. Turn power on. Cycle gate open, and closed to check for proper operation. Close and lock
access doors.
