is consumed distributor gear

hi I have a problem with the gear changed the distributor and after about 600 miles and already half eaten what can it be?

 thank you

Check alignment and verify that both gears are cut at the same angle (number of teeth may be correct but if at the wrong angle they may engage, but self destruct).  Good Luck   Fred  

thanks Fred could be the game of the shaft of the distributor now I put a 0.008 inch

The new gear is not mellonized. It is incompatible with the camshaft material. Distributor gear wear is very common when guys start swapping parts around without knowing about the material requirements. Roller-lifter cams require a melonized gear. Or the distributor gear gets eaten very quickly.

understood

 you tell me the cams and gears  differences?

Google "melonized distributor gear". You ought to end up really confused.

One of the things I've learned about this subject is that the bronze distributor gears many people suggest are NOT a solution for street engines. They don't last more than 1,000 miles. Race-car only stuff.  If you start purchasing gears, pay attention to distributor shaft diameter. There are 3 different diameters.

I've never had trouble by sticking with the stock gear on the stock cam. The problems seem to arise when people swap an aftermarket distributor onto a stock factory roller-lifter camshaft. The roller-cams are a hardened steel material that eats up a gear intended for a 'softer' iron-material non-roller cam.

ok then you say that if I mount an original should not have problems

I know this is an old post   & i don't know if that engine has or dose not have a roller cam I have a roller cam in my ZZ4 block with a Bronze distributor gear (aftermarket distributor) and I have well over 20,000 miles on it Comp.cams has a composite gear that Racers are now using
