11. Turn the planetary gearbox again as shown in the figure on the left:
Bore 6 in 6 o'clock position.
12. For checking the oil level, loosen the screw plug of the bore 5 slowly, so that any
existing pressure can be released. Then remove the screw plug again from the
bore 5. The oil level is correct if some lubricating oil escapes from the bore 5
when the planetary gearbox is at standstill.
13. If the oil level is too low, fill lubricating oil via bore 5 until it drains from bore 5.
14. Check whether the seal on the screw plug thread of the bore 5 is still in perfect
condition and can be reused. Replace a damaged seal.
15. Seal bore 5 with the corresponding screw plug.
Filling the planetary gearbox K model with lubricating oil.
f Refer to the figure on the left
• Bore 10: for filling or checking the lubricating oil
• Bore 9 for draining the lubricating oil
1. Turn the planetary gearbox as shown in the figure on the left: Bore 9 in 6 o'clock
position.
2. Place a catch basin with sufficient capacity under the planetary gearbox.
3. Loosen the screw plugs of the bore 10 slowly, so that any existing pressure can
be released.
4. Then remove the screw plug from bore 10.
5. Refer to the technical data sheet in appendix D "Technical data / Drawings"
of the material number-specific operating instructions for information on oil
viscosity and oil capacity.
6. Fill the planetary gearbox with clean lubricating oil via the bore 10. Fill sufficient
lubricating oil until some oil drains from bore 10.
7. Check whether the seal on the screw plug thread of the bore 10 is still in perfect
condition and can be reused. Replace a damaged seal.
8. Seal bore 10 with the corresponding screw plug.
9. Let the HYDROTRAC GFT planetary gearbox run for approx. 5-10 minutes.
10. Allow the planetary gearbox to cool down to approx. 50°C after switching off.
11. Turn the planetary gearbox again as shown in the figure on the left:
Bore 9 in 6 o'clock position.
12. For checking the oil level, loosen the screw plug of the bore 10 slowly, so that
any existing pressure can be released. Then remove the screw plug again from
the bore 10. The oil level is correct if some lubricating oil escapes from the
bore 10 when the planetary gearbox is at standstill.
13. If the oil level is too low, fill lubricating oil via bore 10 until it drains from
bore 10.
14. Check whether the seal on the screw plug thread of the bore 10 is still in perfect
condition and can be reused. Replace a damaged seal.
15. Seal bore 10 with the corresponding screw plug.
