Overrun brake housing AL-KO 2.8VB diameter 60 mm

The original housing for the 60 mm diameter pull tube of the overrun brake AL-KO 2.8 VB/1 is supplied in one piece. However, we recommend that you always change the sleeves in pairs - the front and rear sleeves are identical. Excessive play in one bushing significantly affects the life of the other bushing.

The pulling tube of the ramp brakes has a diameter of 60 mm. The bushing always has a smaller inner diameter and after pressing into the brake body it must be calibrated to the exact diameter of the pulling tube used. Before replacing the bushings, we recommend that you assess the state of wear on the surface of the towing tube and, if necessary, replace the tube together with the bushings. The surface of the towing tube should be completely smooth. Any unevenness of the surface leads to a reduced service life of the new bushings.

CAUTION: After pressing the bushings into the ramp brake body, it is necessary to ream the bushings (preferably with a manual adjustable reamer with extended guide) to the exact diameter of the pulling tube. Before inserting the pulling tube, it is necessary to drill holes for grease in the lubrication points. Improper installation can lead to irreversible damage to the bushings or other parts of the brake system.

We recommend that you entrust the replacement of bushings to a trained workshop with the appropriate workshop equipment. In our service we will reinstall the brake after prior ordering (repair time depending on the condition and age of the brake about 80 - 120 minutes).
