The front Bendix Bolt is broken off 1/8" below the surface that left a rough hole in the front disk of the Bendix and the Bendix spring is removed. I tried to center-punch the bolt in the hole and drill it out with small drills enlarging the drills a step at a time but I don't have the power to center-punch the broken off bolt and even when I try a little off-center the drill just dances around because I don't have the strength to force the drill into the bolt. I locked the Bendix disk in position with vice grips so that it would not rotate.
I am thinking that I can remove the four mounting bolts and slide the starter forward and take the starter to my powerful floor drill press, lock the Bendix part with the broken bolt into the drill press vise, center-punch the bolt and drill it out.
Any other suggestions ? thanks, Frank
If it were me, I would remove the starter (disconnect the negative battery cable first if you haven't already done so), it will make things much easier to work on. Do you have any left hand drill bits? sometimes drilling with a LH drill bit will remove the broken bolt without having to use an extractor.
Mark, I do have a set of the square type of extractors the have sharp knife-like edges that are pounded into the drilled hole.
Before you try center punching it again, make sure the starter shaft is well supported so that you don't bend it, and if you have a small grinding stone that can fit in the hole (maybe one of the small Dremel tool stones?), grind the end of the broken bolt flat to make it easier to center punch and reduce the tendency for the drill bit to wander.
Yes as I stated above I will mount the shaft in the large drill-press vise. I do have a set of small grinding metals in stone and tool steel.
Does your car have a magneto? If not, try to remove the whole starter with the bendix in place. If you still have a working magneto, try to drill out the bolt and use an extractor. Only the outer sleeve is threaded, so even if you ruin the threads, you can still save the starter shaft.
You can't remove the starter with the bendix still attached, It hits the Mag ring and flywheel. The only way to remove the starter with bendix still attached is to remove the hogshead with the starter still attached, then you can pull the starter off.
My bad, I forgot about having to remove the Bendix before attempting to remove the starter, my apologies.
Norman it is a highly modified flat head T engine with special cam, pistons, and 8.6 compression ratio that puts 48.6 horsepower to the rear wheels. Thanks for the part about the shaft not being threaded, I looked at a spare shaft and found that all the front hole does is to hold the spring in position.
Why can't I simply pull the Bendix collars off to the rear with a puller ?
"Why can't I simply pull the Bendix collars off to the rear with a puller ? "
Because the end of the bolt is in the shaft and it will prevent the collar from moving.
Frank, that bolt doesn't do anything except hold the spring. Remove the back bolt and slide off the bendix. Then deal with the broken bolt.
Thank you Kenny ;~)
Holy cow! Kenny is right!
