Starter and Flywheel Trouble
Hey All, thanks to those who aided with advice about my diff switch, will definately let you all know how it goes. Now on to another question...
'82 Bronco XLT Lariat, 351W, C6 I have had it for two years now and have had trouble with the starter not properly engaging the flywheel. I am about to replace my second flywheel, but that got teeth broken when it was -45 degrees and my block heater died. Before that it was working well, but in order to get it to work right my mechanic had to change the starter monting holes to a slot, by drilling it out, then putting a spacer in the slot to keep the starter in the new position. This seemed to work, but makes me wonder if something else is actually wrong. I have been told that Fords are notorious for having starter problems.
Anyone got any experince with or ideas about this one?
Thanks!!
btw, even with the troubles, I love my bronco!

I think you may have hurt the flywheel because the block heater wasn't working and the oil was like tar. Never heard of slotting the bolt holes before, that sounds like a shadetree fix. If you are running the gear reduction starter ( sometimes called a high torque starter and it is smaller than a stock one) they have some adjustment in the lower bolt hole, other wise the stock starter should not require any mod. I would make sure you are getting the right flywheel installed. Also, does this only happen when it's cold, because that may be more related to heavy starter load from the cold fluids. Just my .02,

if your starter gear doesnot mesh correctly with the flywheel you will definatly break teeth. fords are usually pretty good with the correct meshing of the teeth, chevy is another story. they use shims to adjust gear mash.
i have had to do this modification to a starter on a ford mustang back years ago.
my suggestion would be to replace the starter when you replkace the flywheel because the starter gear may be worn also and that would wear the flywheel gear out. in my opinion -45 degrees should have no effect on the gears breaking but improper mesh of the gears with the extra strenght or torque of the starter needed to start a cold engine could break teeth off.
are your broken teeth completely gone or are they only boken half off.?

extent of damge
I am not sure of the extent of the damage, I have not yet opened it up. I should be doing that this week. I was actually considering replacing the starters as well, just to be on the safe side. I'll let you know more about what itlooks like when I get it opened up. Thanks for the advice!

I'v replaced the flywheel once and the starter 3times on my bronco in the past 2 years, but thats because the starter would work its self loose and chew the teeth off the end of the gear, it still doesn't engage right but it works?

I had to put 3 new starters in my truck over the past year. I was actually using a 10 tooth instead of a 9 tooth, to get it to mesh right. I ended up having my transmission rebuilt and I had a B&M flywheel put on, and now I have no problems and I have the original 9 tooth starter in there. Even when we pulled the old stock flywheel off it looked good, but it must of just had a slight worp to it? Anyway I hope this helps.
