The recall says specifically to INSPECT the existing bolt and replace ONLY IF NECCESARY. The newer design was available long before the recall was ever launched- it was not a designed upgrade. What's more important is that the proper torque is applied to the bolt. I've recently had a 96 SR come in with a "newer style" bolt that had backed off damaging the crank gear and dampener. On top of that, the recall tightening procedure was done close to 2 years prior. Upon interviewing with the customer- we learned that the timing belt had been replaced within a few weeks of this existing failure. I'm convinced that the bolt was not tightened properly to the 135FT/lbs specifications resulting in the failure.
