DIFFERENT FELLER
I LOOKED AT 3 ONLINE PARTS STORES, 157 TOOTH SEEMS TO BE THE NORM ON A 289
MAYBE MR. STARTER MIGHT HAVE THE WRONG TEETH OR BE THE WRONG STARTER?
RAN INTO THAT ON MY DAD'S '76 F-150, SOMEONE JUST SLAPPED ON ANOTHER FROM ANOTHER FORD. MANY FORD'S WILL "FIT" THE HOLE, THROW AND TOOTH COUNT MAY BE WRONG, BUT STILL SORTA WORK FOR A WHILE. 'TIL THINGS CHEW A WHILE
WHEN HE GOT A REPLACEMENT, THE STORE DECIDED THE "CORRECT ONE" WAS NOT A MATCH TO THE (WRONG) OLD ONE. SO THEY COMPENSATED (WRONG THING TO DO)
IT TOOK ME 3 MINUTES TO INSTALL IT, UPON STARTING, IT TOOK ONLY A MILLISECOND TO BUST OFF BOTH EARS, AND LEFT IT A DANGLING BY THE CABLE!
NOT SAYING THIS IS YOUR CASE, BUT MAYBE WORTH COMPARING IT TO ONE AT A PARTS STORE
THE "BANG" MAY ALSO HAVE BEEN THE FLYWHEEL ROTATION SUDDENLY HITTING THE GAP IN THE TEETH, AND SLAMMING INTO THE NEXT BETTER TEETH
OR, AS THE STARTER'S TEETH WERE RETRACTING NICE AND SMOOTHLY, STILL MESHING SMOOTHLY WITH GOOD FLYWHEEL TEETH ON IT'S WAY OUT. BOOM. HERE COMES THE GAP TO INTERRUPT THE FLOW OF THINGS!
MY '46 WILLYS JEEP STARTER RELIES ON A LARGE ECCENTRIC WASHER (SORTA OFF CENTERED ON THE STARTER SHAFT) TO "WEIGHT" THE STARTER DRIVE SO THAT WHEN I HIT "START" IT MOMENTARILY HOLDS IT STILL WHILE THE STARTER SHAFT SORTA "SCREWS" THE TEETH INTO THE FLYWHEEL, ONCE IN THERE, IT'S AT THE END OF "SCREW TRAVEL" AND IT BEGINS TO ROTATE THE FLYWHEEL
WHEN IT CRANKS UP, AND I RELEASE THE KEY, THE FLYWHEEL TOOTH ENGAGEMENT WITH THE STARTERS TEETH "UNSCREWS" THE STARTER DRIVE BACK INTO THE STARTER. A VERY LIGHT SPRING ON THE STARTER DRIVE HOLDS IT FROM "FLOPPING" BACK INTO THE FLYWHEEL TEETH (THIS SPRING IS SO LIGHT, IT DOES NOT SHOVE IT BACK OUT OF THE FLYWHEEL, WHEN CRANKED UP)
THE MORAL OF THAT STORY IS
IT IS NORMAL FOR TEETH TO STILL "MESH" (FOR MOMENTS) WHEN IT'S CRANKED UP, AND STARTER IS IN THE DISENGAGEMENT PROCESS. IT'S NOT A "SLAM IN" AND "JERK OUT" KINDA THING, BEFORE THE TEETH CAN CATCH THE NEXT TOOTH!
OUR OTHER "DEFAULT STARTER" IS FOOLPROOF, AND WILL NEVER BREAK, AS DEMONSTRATED BY MY DAUGHTER WHEN SHE WAS 10!
