Belt Replacement; Belt Tension; Drive Chain Alignment And Tension - HYTROL Gapper-D Manual De Instalación Y Mantenimiento

• Belt Replacement

The conveyor belt has been cut to the proper length and spliced
together for endless joining. To replace a belt, follow these steps:
1. Loosen belt by loosening the take-up bolt weldment on the spring
take-up until belt is no longer in tension.
2. Remove tail pulleys, drive pulley and slider pan.
3. The new belt can be installed as shown in Figure 6A.
4. Slide belt over tail pulleys. Belt is installed on top of Auto Belt
Tracker and over Take-up pulley.
5. Put slider pan in place.
6. Reinstall drive pulley being careful belt is in proper position.
7. Tighten hardware.
8. Adjust belt tension by adjusting the take-up bolt weldment on the
spring take-up. See Belt Tension section.

• Belt Tension

The Spring take-up prevents over-tensioning of the belt. The yellow
spring tension guide located on the spring
tensioner provides a quick and easy way to
adjust to the desired tension. To adjust to the
proper tension, turn the 1/2-13 hex nut on the end
of the take-up bolt weldment until the take-up lug
is aligned with the corresponding BR as shown
in Figure 6B.

• Drive Chain Alignment and Tension

The drive chain and sprockets should be checked periodically for proper tension
and alignment. Improper adjustment will cause extensive wear to the drive
components.
TO MAKE ADJUSTMENTS
1. Remove chain guard.
2. Check sprocket alignment by placing a straightedge across the face of both
sprockets (Figure 6C). Loosen set screws and adjust as needed. Re-tighten set
screws.
3. To adjust chain tension, loosen bolts that fasten motor base to mounting angles,
both sides of the conveyor.
4. Tighten take-up bolts until desired chain tension is reached. (Figures 6D & 6E).
Re-tighten mounting bolts.
5. Lubricate chain per lubrication instructions.
6. Replace chain guard so that it does not interfere with drive.
