Top ABDS tips for top technicians
When installing a new part in the Auxiliary Belt Drive System (ABDS), consider the implications for the other components in the drive. Gates research shows that surface wear resulting in the loss of material can negatively affect the overall performance of the belt.
Just 10% belt slippage can adversely affect the overall drivability of the vehicle. Think in terms of the recent cold snap when power outputs surge. The use of heated seats, cabin heaters and full lighting systems increases throughout the daytime, as well as at night.
In tests, Gates installed a new alternator while the old belt and tensioner were not changed. By replacing just one of the components, the equilibrium of the ABDS changed. The increase in vibration grew until it was noticeable and could be heard or felt.
Imagine the potential for customer complaint.
Replacing the alternator but not the belt and tensioner increases tensioner arm vibration as the worn tensioner fails to dampen the new component effectively. In this case, belt noise increased along with bearing wear in the other ABDS components. Performance of the new component began to suffer due to compromises arising from the associated adverse conditions.
The performance of the components inside the ABDS is integrated. Changing one part can disturb the equilibrium.
So, make a thorough check of the ABDS to ensure that installing a single component does not compromise the integrity of the system and consider installing a Gates kit that includes all of the necessary parts for a drive system overhaul.
