HARMONIC BALANCER REBUILT XJ6 93-94
The Harmonic balancer is no longer made for this car, not original, nor afternarket. The old balancers have to be rebuilt. This balancer when last sold by Jaguar had a list price of $990.00 and sold for about $661.00 average.
The harmonic balancer, also known as the main engine pulley, has a useful lifespan of approximately 10 years. Anytime after then, the rubber mounting between the two pieces is subject to de-lamination failure. The area at the front of the engine is subject extreme heat. This daily heating of the rubber slowly makes the rubber brittle and eventually, failure results. Parts like this should be replaced and not driven into the failure mode. Being stranded beside the road (with no replacement part readily available) can also cause other damage, possibly including the radiator. An old part will usually fail without notice. A failed unit makes a squealing noise (but not always) much like a slipping belt. Also the alternator will read a lower voltage much like a failing alternator.
This unit is guaranteed as long as you own the car!
We can email instructions on how to properly remove the unit and reinstall the new one at purchase.
