Genuine Losi spare/option part. Replacing the pins on DBXL drive shafts LOS252001, LOS252021, LOS252019: Remove set screw completelyOpen bench vise until the pin just fits between the jaws Position shaft on vice, held by a second person if necessaryDrive pin out with light hammer blows using a pin punch or a suitable comparable tool If Loctite was excessively used in the assembly, heating the shaft end may be required. Depending on the thread locking compound, you will strive for a value of 200 - 300°C. The shaft end must not be annealed! An annealed pin will mushroom on impact and make it very difficult to drive it out if not impossible. When installing the new pin from set LOS252020 make sure that the flat section of the pin is positioned under the set screw. The set screw should be just slightly tightened against the pin using high strength thread locker (link). Firm tightening puts the pin under preload and increases the risk of breakage!Contents:1 piece
