How to Repair the Roof of the Smart 450

Model: Smart Smart 450 - Years 1998-2007
Part: Convertible top

It often happens that during the closing and/or opening of the roof, it struggles to reach the end of its travel and latch due to wear on the gears of the motors that operate and drive the mechanism. You can permanently solve this problem by replacing the original gears with rebuilt ones made of hardened steel, which are much tougher and more resistant to wear. The replacement is straightforward as the motors are easily accessible and removable, located at the rear of the roof, hidden by specific caps. Once the motors are removed, use a puller to take out the old gear and insert the new ones.
