Risk of mixing up the tensioner and deflection pulleys in the CT1038K1 and CT1038K2 kits during fitting
The deflection and tensioner pulleys are mixed up during fitting, resulting in incorrect tensioning. This can lead to increased noise and even engine damage.
The two pulleys look almost identical with only a small difference in diameter. As a result, it is easy to mix up the two pulleys.
The deflection pulley V55826 has a diameter of 67mm. The tensioner pulley V55822 has a smaller diameter of 63.7mm.
