Cummins Internal Combustion Engine Belt Tensioner A3914086 Use Attention

​The timing belt needs to be properly maintained to avoid breaking the belt. If the belt is not synchronized with the timing of the camshaft and the valve, problems may occur. Pistons hitting the valves may cause these valves and pistons to bend or damage, as well as damage to the camshaft. These are very expensive repairs that you want to avoid.

You should consult the user manual and replace the timing belt as recommended by the manufacturer. The time interval between each vehicle can vary greatly, so the interval that applies to one vehicle may not necessarily apply to the next vehicle.

You can replace your own timing belt and related hardware, but it is recommended to find a professional to replace it. As mentioned earlier, because the belt is located behind the serpentine belt assembly, it is difficult to operate. Doing the work yourself can save you a lot of money, because the biggest repair cost is labor. If you are going to do this project yourself, please make sure you review the repair guide and fully document the process so that you can return all parts to where they belong.
