    While working in the garage today I dropped my timing gear on the floor, I can see a little damage. So should I replace or use this one. What do you guys think?
    Thank you for any suggestions, as always![​IMG][​IMG][​IMG]

    Carefully file the mushroomed spots out of the lands of the tooth.
     
  3. Once you file it, it should be fine. I would use it.

    Why does the metal look so porous...?

    Inferior metal. Crappy casting.

    Yes it looks porous but I think it is just scratches from hitting the floor. I would file it also -but then I seem to like to do things that wake me up at 3:00 am.

    looks like dirt, not porosity, to me. But it's hard to tell without being there.

    Thank you all for taking the time to look at the photos.
    Yeah it was real dirty from hitting the floor which really made it look somewhat porous in the photos.
    I cleaned it up and filed any burrs from the gear. I think I’ll use it. Really bummed me out to drop a new part on the floor like that!
    Thank again for the help!!

    What’s that gear made of? Cheddar cheese?

    As has been said clean it up and use it.

    Was thinking you could test it in a partially assembled block. Bluing would reveal the clearance 'fit. First rotation trial may not need valve spring loading.

    More than just burrs. Make sure none of the profile of the cog has deformed into the V groove where it meshes with its mating part (chain, belt, gear). And definitely no high spots if its mating to a belt.

    it's a gear, not a pulley or sprocket

    I understand deformation from hitting the ground but to me that shows the material is soft.

    I would be interested how that gear ends up wearing.

    If I throw away everything I drop I would spend a lot of time ordering new parts

    Having dirt on it after hitting the floor concerns me. Every time I build an engine the floor is so clean that you could eat off of it.

    What does that matter? It still mates with a belt, chain, sprocket, or another gear.

    Just that you don't need to be too concerned with it mating with a belt.

    It might not be as finicky as you think.

    A bit like setting up a ring-&-pinion, where the paste 'marks' indicate the mesh.

    Except that there's no adjustment, and you can't hear it. If it still has a little bit of backlash where the teeth got messed up, then your filing job is just fine.

    I'm in the "file down the high spots and run it" crowd.

    File it and you might get lucky, but if you were lucky, you wouldn't have dropped it in the first place :D

    Seriously, there atr three outcomes if you file it and use it as is:

    1. It works fine.
    2. It has an annoying "tick" which might drive you nuts and affect the longevity of the gear.
    3. The gear has been streesed due to the impact and could fail & mess up your engine.

    For the relatively few dollars involved versus the possible cost of repairs due to failure and work to change it, why not just replace it ?

  24. I’d get a different one because that thing is way too soft not because it needs dressed.

    What do I think? I'd replace it. Besides the drop damage, looks like it is starting to wear from the looks of the striations on the tooth faces. I wouldn't try to save it....not worth it to me.

    Quite a few opinions and at the end of the day the only one that matters is yours.
    I’ve rebuilt engines in dirt floor sheds with used parts and others in clean shops with new parts. All ran fine. Never lost sleep over any build.

    No such thing as luck, it's all premeditated carelessness. I'm speaking from experience, you understand;)

    Dropping it on the floor didn't seem to hurt it too bad but..............did you hafta smack it with a sledge hammer!:eek:
    Great Day...it must have bounced like a rubber ball!!!!! J/K:D
    I think a little work with a file and you will be golden.
    Is it a gear drive with a floating idler? I believe "Kong" Pete Jackson's brother-in-law perfected the idea of two different size wheels in the idler. Anybody wanna guess WHY two different size wheels are used?!

    Those aluminum gears are indestructible, compared to the fiber ones!
