Starter DIY Rebuild...or Buy new?

The starter, a Mitsubishi M8T50071, on my 95 7.3 F350 sometimes just has a loud click when I turn the key and it doesn't do anything else. It seems to be getting worse and this afternoon when I tried to start it, it took about 20 times before it engaged. I'm thinking about buying a rebuild kit for it. Has anyone here ever rebuilt one? Any advise?

I have never done a rebuild, but it sounds like the solenoid may be weak. I used to rebuild AC, DC, and servo motors, so I'm not sure why I haven't tried rebuilding my own starter. It should not bee too difficult if the kit has everything you need. I guess you would have to use an ohmmeter to test the armature and windings. So, I guess it all depends on the quality and price of the rebuild kit or parts.

I don't rebuild starters. I just buy a new one with life time warranty. If you rebuild it and it goes bad then you will either have to rebuild it again out of your pocket or buy a new starter. Where if you buy a new starter with lifetime warranty you never have to buy another starter again.

I would make sure it is not a solenoid problem like Pipelayer is saying. I believe that on the 95's the soleniod is not attached to the starter. The solenoid should be on the passenger side fender by the battery.

Thanks for the replies.

After dinner tonight I decided to jump the fender mounted solenoid. With the truck in neutral, I took a doubled piece of #10 Romex and jumped it. I could hear a distinct thud from the area of the starter, but no cranking occurred. I think what I’m hearing is the pinion gear engaging the ring gear. However I don’t know if I’m actually getting any power to the starter motor itself…could be a problem with the starter mounted solenoid, but I’m thinking that is most likely the brushes. It will be Friday before I get a chance to drop the starter and check it out.

The other problem is finding a part store that has a rebuild kit in stock. Back in the day this would be easy to do. But now adays they just have a factory do all the rebuilding. It maybe easier to find a starter in stock then the rebuild kit.

To me, it just makes sense to go lifetime. But that's MHO.

I got a rebuild kit off eBay. I always wanted to do one just becasue, and it was like $50, couldn't pass it up. Pretty neat experience. Then the starter mounted solenoid went bad. Dam thing cost as much as the rebuild kit, I would have been better off just buying a new starter off eBay for $120. I know a ton of guys that have and they work great.
Lifetime warranty is good piece of mind, what's the charge for that type of starter?
If it's a lot more, than not worth it IMO as my experience the 'lifetime' stuff dies rather quickly anyway leading to more R&R work... Maybe it's just me.

Oh, and Fords actually have 2 starter relays.
One on the starter and one on the passenger fender.
Just more stuff to go bad...

An OBS or 2, or 3...

Make sure your batteries, cables, and grounds are all good and clean. I had starting issues with mine and it ended up just being a bad battery and it ended up just being a bad battery.

Go to Ford or International and buy one! A new one, i went through 5 reman with life time warrantys from different parts stores. 5 starters in about 6 months, it got old quick, they would leave me stranded, stay engaged and are not the most pleasent to change out in a parking lot in the cold and rain. Save yourself some head aches and spend the extra money and buy a new one
