Honda did a good job engineering the B-series' timing belt configuration. For the average commuter who replaces their timing belt on a regular basis and doesn't spend the majority of engine operation in the 8,000rpm zone, the OEM setup is just fine. But high-rpm engines can stress Honda's belt in ways B-series engineers never imagined. Making sure that the belt is replaced on a regular basis; that the OEM tensioner is installed correctly and in good working order; and accompanying the system with a supplemental tensioner like Vibrant's is a good start to ensure the timing belt is the last place you'll find your next problem.
Timing belts are tensioned...
Timing belts are tensioned by either a bearing-type tensioner (shown here) or a hydraulic filled, piston-type tension such as those used by Honda H-series engines and Mitsubishi's 4G63. When the bearing tensioner's bolt is loosened, the pulley can be moved left or right, allowing the proper amount of tension to be imparted on the belt.
Vibrant Performance's adjustable...
Vibrant Performance's adjustable timing belt tensioner attaches to the front of the engine block and adjusts both vertically and front to rear for precise placement.
The tensioner is constructed...
The tensioner is constructed of T6061 billet aluminum, so it's light and strong.
Vibrant's tensioner pulley...
Vibrant's tensioner pulley features a special coating to help prevent unnecessary belt friction and to not mess with Honda's 60,000 mile replacement interval.
The pulley can be driven closer...
The pulley can be driven closer to the belt by adjusting the set screw and then locked into place by tightening the through bolt.
