Dist-cam gear alingnent



Rich,
In most cases you cannot war out one gear without doing damage to the other gear. If one gear is damaged then the damaged gear will in turn damage any new gear you install with it. Most folks ruin a gear, then continue to add new gear to replace the bad gear and often will eat up 3-4 gears before realizing the gear they are not replacing is causing the problem.


The next thing is gear compatability. Every gear made for AMC is not compatable with every other gear made for AMC. Many, many folks sell CROWN gears as real AMC gears. They ARE NOT!!!!! The tooth shape is not correct to mesh with other brands of gears. MATCHED SETS of gears don't seem to have problems.

Yes, in most every case you can shim distributior gerars. All you do is check the endplay and add distributor shims to set the end clearence. Many stone stock point type distributors have way too much end play for proper timing to be3 closely maintained. When the distributor shaft moves up and dpown it changes the timing .

There are many issues which cause distributor gear problems. Oiling , brands of gears, cam walk, etc. You must first determine WHY you are having the problem, then fix the problem. Just tossing in gear after gear does nothing except pump you oil system completely full of metal shavings which in turn wipes out all the bearings & eats up the crank.

Good Luck,

Randy Guynn
