Apparently the verdict is in even though the Judge (Dan) has not seen the evidence yet. However given this new information (new to me anyway), I will no longer tighten the timing gear to the mythical 100 ft lbs, I will instead use Dan's recommended 50 lbs. Also, I will clamp the gear to avoid damaging the teeth.

Unfortunately this experience also causes me to question the guidance of several well known and recommended sources.

Interesting to note, this is the fifth engine I've rebuilt, the other four had laminated gears and now it seems all were torqued too much and tightened incorrectly. Yet this one is the only one that seems to have sustained damage. Doe this same procedure need to be done for macerated and laminated gears as well, or only aluminum? How about the bronze ones? Perhaps someone else can chime in and state whether they've damaged other gears by over torquing and blocking the crank or as others have mentioned using the "rag" method?

In regards to H.L. Chauvin's comments to Dan: "it may be better to hear from you about how "NOT" to follow the forever "written" and recommended timing gear tightening method" and Greg Jones comments to Dan: "it might be a great public service to tell the community", I agree and I simply suggest that an instruction sheet with the correct procedure be included with the gear when purchased. I suppose however that this suggestion might prompt other forum members to simply say "Ignorantia juris non excusat".
