Housing brake AL-KO 2.8VB diameter 60 mm

The original case for storing the 60 mm diameter pull pipe of the AL-KO 2.8 VB/1 overrun brake is supplied one piece. Nevertheless, we recommend always changing the cases in pairs - the front and back cases are the same. Excessive play in one bushing significantly affects the life of the other bushing.

The pull tube of the overrun brake has a diameter of 60 mm. The inner diameter of the bushing is always smaller and after being pressed into the brake body, it is necessary to calibrate it to the exact diameter of the used draw pipe. Before replacing the bushings, we recommend assessing the state of wear on the surface of the towing pipe and, if necessary, replacing the bushings as well as the pipe. The surface of the draw pipe should be completely smooth. Any unevenness of the surface leads to a reduced service life of the new bushings.

ATTENTION: After pressing the bushings into the body of the overrun brake, it is necessary to ream the bushings (preferably with a manual adjustable reamer with an extended guide) to the exact diameter of the draw pipe. Before inserting the draw tube, it is necessary to drill holes for the lubricating grease in the place of the lubricators. Improper installation can lead to irreversible damage to the bushings or other parts of the brake system.

We recommend entrusting the replacement of the bushings to a trained service center with the appropriate workshop equipment. In our service, we will re-encase your service brake after prior ordering (repair time, depending on the condition and age of the brake, approx. 80 - 120 minutes).
