How to test/inspect 8 cyl timing gears before failure?

I have a 1942 C8. 
Nice car but as I am refurbishing all the mechanical systems in preparation for touring, I am wondering about the timing gears. I wouldn't want their failure to spoil a long trip. 

I dont want to open the engine just to look at them. And if I did, I think I would just go ahead and replace them. 

Is there a method where they can be easily inspected/tested/evaluated for wear or imminent failure?

    The best option is to put an alloy timing gear on if you can find one.  It is a matter of when not if it will fail if its never been replaced.  Taking the timing cover off and looking at the gear will not help.  Even new ones can fail in short order.  It is not a big job but if it breaks it is a bigger job ie off with the sump to clear out all the debris from the broken gear

    I agree.  The aluminum ones are not easy to find (you have to find the matching crankshaft gear too) but they're out there.  There's a trick to installing them, though; the web of the gear has to be machined to clear a bolt head on the face of the engine block, as I recall.  It's not a big deal to do.

     In the meantime, buy yourself a replacement fiber one (they're fairly inexpensive) and acquaint yourself on how to do a replacement, should your gear fail.  Pack the replacement gear and any necessary specialty tools, in your trunk.  Your present gear may have many thousands of miles left on it, but "be prepared".  

    Once you change to the aluminum gear, you're on Easy Street.  I replaced the one in my '37 back in 1978 and haven't had a bit of trouble with it.

    Is there some reason that no one has had aluminum gear sets made for 6 an8 Hudson motors is this something worth looking into I im more then willing to look into this if ther is enough people who would buy them.

    A lot of people have talked about this for many years. It took me 3 or 4 years to sell my last 2, cause Im in Australia and the postage.  I like the idea of an aluminium gear for the 1934 to 1940 so that we can keep the original crank gear.

    The ROC had some alloy ones made up a while back.
     I don't know whether there are any left.
     I have one but need the small steel gear to go with it - has anyone got a useable one, please ?
