Brake bushings AL-KO 90 S dia. 35 mm new design (square), pair

Set of original tow tube mounting bushings, diameter 35 mm, for brakes AL-KO type 90S/3 and 60S/2. The set consists of one front and one rear case. The front sleeve has a groove for fitting a rubber cuff. This type of bushing, which is square on the outside, is suitable for newer brakes AL-KO (older types of brakes used bushings with a round outside).

The pulling tube of these ramp brakes has a diameter of 35 mm. The bushings always have a smaller inner diameter and after pressing them into the brake body they 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).
