Linear transfer system LFA
Version 1.0
7.3.1
Re-tensioning the chain
To re-tension the chain, proceed as follows:
The linear transfer system has been disconnected from all power supplies.
1. Loosen the cylinder head screws (9) on clamp B of the side panel on both sides by a quarter turn.
2. Slacken chain tensioner A by loosening the hexagon nut (10) and screwing back the hexagon bolt (1).
3. Set the chain tension by gradually turning the hexagon bolt (1) in the clockwise direction while constantly checking
the pretension of the deep groove ball bearing (2) at bearing C on both sides.
4. Check the 16 deep groove ball bearings (2) for correct pretension along the entire circumference of the deflection
wheel (6).
5. The pretension is correct when the deep groove ball bearings (2) can be turned tightly by hand.
6. Use a torque wrench (torque 28 Nm) to tighten the cylinder head screws (9) on clamp B on the mounting plate on
both sides.
7. Repeat step 4. If the pretension of the deep groove ball bearings (2) is not correct, start again at step 1.
8. Secure the hexagon bolt (1) against turning and tighten the hexagon nut (10).
The chain tension is correctly adjusted.
