Why no puller (according to Haynes and common experience): Standard pullers can mar the crankshaft or break the balancer's mounting ring. The design of this particular balancer may make it especially susceptible to damage with a puller.
Safe Removal Methods (Prioritize these):
1. Penetrating Oil and Patience: This is the KEY to success. Generously apply a high-quality penetrating oil (like PB Blaster, Liquid Wrench, Kroil) to the interface between the balancer and the crankshaft. Let it soak for *hours*, or even overnight. Reapply several times. The goal is to break down corrosion and rust that's likely holding it fast.
2. Impacting (Very Carefully): After the penetrating oil has had ample time to work, you can try gentle impacts. Use a brass or nylon mallet (to avoid damaging the balancer) and carefully tap the back of the balancer around its circumference. *Avoid any forceful blows*. The idea is to loosen it slightly, not to break it.
3. Three-Jaw Puller (If Absolutely Necessary and Used Correctly): *Only if the above methods fail* and you understand the risks, consider a *three-jaw puller specifically designed for harmonic balancers*. These are different from standard pullers and distribute force more evenly. Even then, proceed with extreme caution and ensure the jaws are properly seated on the balancer's outer ring, not directly against the rubber damper. Apply pressure slowly and steadily. If the puller slips or feels like it's applying too much pressure to the snout, STOP immediately.
Important Considerations:
* Engine Support: Securely support the engine to prevent it from shifting or falling during removal.
* Crankshaft Protection: Protect the crankshaft threads and snout from damage. Use a clean rag or appropriate cover if necessary.
* Safety First: Wear safety glasses. Pulling a stuck balancer can be unpredictable.
If you're uncomfortable with this procedure: It's best to take your car to a qualified mechanic. Damaging the crankshaft or balancer is far more expensive to fix than paying for professional help. The risk of damage outweighs the cost of professional service in this case.
