Now I know why there is no spark.

From what I read on the forum, aluminum would be the best investment.

The cost is about the same... I guess the only down side to aluminum is from what I've read a little more noise. FrankW on this forum replaced his with Aluminum, you you may wish to ask his thoughts on it...
 
This engine is in the 29 clampet mobile, AKA the Anna Mobile. Noise will not be a problem.
 
that metal gears make more noise is a myth. Aluminum and bronze are metal, but soft metals. Whole different story if you had steel against steel

in this case, the fiber gear did what they are all known to do: disintegrate

too many threads on this already
 
I don't agree with tb, I had an aluminum on a B motor and it was loud. I took it off and went back to fiber. This will start a fire storm.
 
if that was the case then you had a mesh problem. Your centerline to centerline distance was off....you had too much lash
 
I bought gears from Dan McEachern out in CA on tb's advice. I have not had the chance to install them yet (school and all that), but they look amazing.

I went ahead and bought both, but you can just buy one or the other. One is bronze and the other is heat treated steel.

This is what I used also.
 
If your metal gears are loud, your block line bore is off in one direction or another. If its done correctly, you wont hear the gears.
 
This engine will probably not be driven more than 500 miles. I have a newly professional rebuilt engine that I plan to put into this toy for a breakin period. Just wanted to wait until warm weather.
 
"How about 30,000 miles on a fiber timing gear? Working for me."

That is great!
keep an eye on it. Pull the side cover now and then and inspect.
Remember when it does trash itself you will have to do more than change the gear out.
You will have to drop the pan and clean the mess created so that shreds and pieces do not clog your oil pump.
 
OK I got a new timing gear and the tool to remove the old one.
I have tried an impact wrench with 150 pounds of pressure. I have clamped old timing gear. I have used torch and heated well. I have used a chisel with about a 5 pound hammer. I haven't moved the nut at all.
I am spraying it with a mixture of acetone and ATF. What do I try next?

You could always just buy a new Bill Stipe IB330 camshaft to go with your new timing gear. :D
 
The engine is still in the car. Radiator removed. I will soak it good for a day or two. If the impact wrench won't loosen it then, I will get the drill and give that a try. Thanks for the help. I think I will buy the hex nut to replace this old one.
