5.6. Check the Gearbox Oil
1. Remove sweep from lower gearbox
2. Remove access panel at center to expose lower gearbox.
3. Remove vent plug to check gearbox oil level.
4. Maintain oil level at half full (center of cross shaft) with 90W or equivalent gear oil, adding as necessary.
5. Ensure gearbox is level when checking or refilling.
6. Do not overfill when adding oil.
7. Replace vent plug.
8. Replace access panels when complete.
8. Follow same procedure dor sweep gearbox.
5.7. Change the Gearbox Oil
Use SAE approved 90W or equivalent gear oil.
1. Remove gearbox from the bin unload.
2. Place a pan under the drain plug.
3. Use a wrench and remove the drain plug.
4. Loosen the filler plug so air can enter the gearbox and the oil will drain freely.
5. Allow the oil to drain completely.
6. Replace the drain plug.
7. Add oil until the gearbox is half full (center of cross shaft) and replace filler plug. A flexible funnel may be
required. Gearbox should be level when checking or refilling.
Do not overfill.
8. Reinstall the gearbox and guards.
5.8. Tension the Belt Drive
1. Remove guard and push on the center of the belt span with a force of approximately 5 lb. The belts will
deflect approximately 1/2" (13 mm) when properly tensioned.
2. Tighten or loosen the drive belts (or idler pulley when equipped) to achieve the proper tension.
Important
The drive belt should be just tight enough to not slip on the drive pulley when operating. If the belt is too
loose, it will slip, possibly causing a squeaking sound and slowing the belt down. If the belt is too tight, it
will cause excess wear.
3. The belt tension can be adjusted by moving the belt tensioner notch up or down on the motor mount plate.
4. Reattach and secure guard. Start system to ensure proper operation.
