DAYCO HARMONIC BALANCERS
Increased power with “total reliability”
The Dayco Powerbond harmonic balancer range includes a number of precision engineered applications designed specifically for high performance and racing vehicles.
Dayco says its Powerbond Street Series delivers bonded balancer technology within the budget of every performance street engine builder while also being an excellent option for heavy duty OEM balancer replacements. The bonded dampening rubber eliminates spinning and component separation, providing reliable performance in engines used to 6,500rpm, and these balancers combine new high strength SG (Nodular) Iron Balancer centres and inertia rings, which have been bonded and balanced to extremely tight tolerances. To assist automotive technicians and enthusiasts, Dayco Powerbond Street balancers also feature easy to read permanently etched timing marks on the outer ring.
The Dayco Powerbond Race Series reportedly brings the advantages of bonded balancers to high revving race applications where an SFI approved balancer is required. Every Race Series Powerbond balancer features a precision CNC machined AUSI 1045 forged steel hub bonded to an equally strong steel inertia ring.
Dayco says this highly advanced design ensures that Powerbond Race Series balancers are extremely light for an all-steel product and in most cases, they are only marginally heavier than the original cast iron balancer and generally much lighter than other all-steel balancers available in the aftermarket. In addition, the steel inertia ring of the Race Series models is positively protected against forward and backward movement and has the assurance of bonded rubber to eliminate spinning; and every model has easy to read laser etched timing marks. All Powerbond Race series balancers meet SFI specification 18.1.
The Dayco Powerbond Underdrive balancer is a smaller and lighter harmonic balancer that acts like a lightweight flywheel which under-drives the accessory pulleys to reduce parasitic power losses from the alternator, air conditioning, water pump and power steering at high engine RPMs.
Dayco Powerbond Overdrive balancers are suitable where a supercharged engine requires more boost. This is achieved by increasing the diameter of the harmonic balancer, which in turn increases the speed of the supercharger. Dayco Powerbond overdrive balancers are available five percent to 18 percent bigger in diameter and also feature an eight-rib serpentine drive for maximum belt grip. Dayco Powerbond supercharger balancers offer twin keyways for secure crank mounting and have extra bolt holes for bolting on the factory pulley or six bolt Gilmer drives.
Dayco’s Powerbond range also features power pulley kits for a complete heavy-duty fitment of under driven harmonic balancers.
Dayco has responded to market demand and introduced a high quality Nissan Navara OEM replacement harmonic balancer (Dayco Part Number HBB1882N) for models manufactured from May 2015 onwards. This part number also suits Mercedes-Benz X220d and X250d models manufactured from December 2017.
