As with all engine components, the harmonic balancer will eventually fail and need to be replaced. The rubber layer between the metal parts is often the source of the failure. The adhesive bond between them can fail and cause the parts to slip, reducing the amount of power transferred. The engine accessories may not function properly when this happens as they do not turn at the required speed. The rubber can also break apart internally and cause a total failure of the balancer. Cracks on the visible edge of the rubber layer are a sign that it is deteriorating. The seal behind the balancer should also be replaced if there is oil leaking from it, as oil makes the rubber deteriorate faster.
It is often difficult to remove the harmonic balancer because of its tight fit with the crankshaft. However, a special tool called a balancer puller can make the task easier. The puller is a metal hub that attaches to the balancer with several bolts, and has a center bolt that presses against the end of the crankshaft. When the center bolt is turned, the puller pushes against the crankshaft and draws the balancer off it. After the balancer has been removed, the shaft key and slot should be inspected for damage and the key replaced if there are any chips or cracks.
Installing a harmonic balancer can be just as difficult as removing it. The contact surfaces on the crankshaft and balancer should be lightly oiled so that they slide together more easily. The balancer can be pushed onto the crankshaft by turning a bolt in the center hole. Since the locking bolt is too small for this, a larger bolt must be found with the same thread. To avoid stripping the thread in the crankshaft, the bolt should have several turns on it before any force is applied. It may be necessary to first tap the balancer on with a rubber mallet. Once the balancer is on the crankshaft, the locking bolt is secured with the correct torque.
Start with fuel pressure checking.If fuel pressure checks ok, then go for other troubleshooting possibilities.--------
