Stripped electrical post on starter

[Rozie]

The electrical post is stripped on the starter which connects to the selenoid. I need to replace it but am weary of opening up the starter. Any tips for me before I open up the starter to make sure the brushes etc don't fall out. I've heard they can be a pain to put back together. Thanks in advance

Rethread it down to the next size, use a smaller nut with a washer. Worth a shot !

Repair studs are available and are probably a good thing for you, if you are not experienced in repairing starters, including soldering a new stud in place.

You remove the nut that is still on the stripped stud and screw the repair stud in place, down to the good threads.

I like both of those ideas. I know a guy with retread tools. I will see if I can get my hands on them. Thanks. Much easier than cracking the starter open.

Just to let you know it takes a heap big soldering iron to solder in a new stud and your big soldering gun is not near big enough to do that job

IIRC, it's 5/16", trying to re-thread it to 1/4" won't leave much.

I have some extra of the repair studs, I'll send you one for FREE, if you'd like.

Just would need to versify the stud thread size, I'm THINKING 5/15" NF.

Let me know if you'd like one.

In my opinion, I would pull the starter and take it to my local reputable starter/alternator guy and have him install a new stud. He has all the tools and expertise to do it and maybe, if he knows you well, won't charge you much. Key to preventing stripping threads is to always finger start a fastener and try to screw on up until it binds to the mating part, then use a wrench for final torqueing. If a fastener gets hard to turn by hand, chances are it is cross-threaded so stop and try again. If threads are real rusty and/or dirty, try running a thread die over the stud but be careful not to cross-thread it and most importantly, be certain you have the correct size that matches the stud threads. Most nominal thread sizes come in both a coarse and a fine thread pitch. For example, a 1/4" nominal size has a 20 TPI and a 28 TPI (Threads Per Inch)and trying to screw a 28 pitch onto a 20 pitch will bind up almost immediately but I've known fellas that then take their air wrench or socket wrench and force the nut onto the stud therefore stripping it. Do the job right the first time. Why risk making things worse trying turn the stud down and going smaller, as that probably won't work nor last long being so small and weak. The last thing to prevent stripping is over tightening. many don't know their own strength and will use a breaker bar on everything. Just giving my advice...

Bob, where might these repair studs be found? Looks like it might be a good thing to throw into the tractor tool box just in case.

Looks like you would have to cut some off of the stripped stud so that nut shaped part could fit down on the undamaged threads.

Never mind, found them on Amazon. :wink:

 

[Rozie]

I was looking for them online and couldn't find them.
Suggestions?

Bob I agree I would love it to not be stripped in the first place. I stripped plenty of bolts in my day but this one was actually the starter repair guy about 5 years ago. I needed to take the nut off to find out the repair guy stripped it last time. I trotting down to have him fix it and of course the place went out of business.

 

[Rozie]

Thanks for the offer. I will get you the size tomorrow.

 

[Rozie]

Can't I just screw on the new replacement stud over the starter stud? I have minimal soldering skills.

 

[old]

Yes the stud that goes over the stripped one does just that all I was saying is that it is not easy to solder in a new stud and it takes a big iron to do so or in other words not for the unskilled person

 

[Bob]

Rozie got back to me with an address and I have mailed him a repair stud.
