How to change the starter on DETROIT 12.7

Better in every way except the fact it cost twice as much and lasts half as long.

 

It will make the truck sound like a 318 dodge pu truck when it starts

 

I had a guy tell me mitsubishi starter is the best anyone know about those?

 

Not true.,,,

The old Black 42mt I was going thru 1 every 3 years...

I Bought the 39mt.....Install it with 1 hand, Gear reduction starter with, Hasn't given me any issues,

Oh, you can get them for around $200 NEW on ebay

 

China junk new for 200 you mean. I'm gonna go with what my starter and alternator guy says. He rebuilds 5 or more a day. I change one once every million miles. I'll stick with the old style 42mt built with American parts by Americans with thirty years experience. 150$ out the door and delivered if needed.

Edit to add: no matter which starter a guy goes with keep that battery system in tip top shape. Low voltage drastically reduces a starters life.

 

I've had nothing but good luck with the gear reduction 39mt . Lasts way longer then the old style 42mt.
Mitsubishi seem to be the best .
Don't buy the cheap one.

 

Suprised this wasn't mentioned earlier lol.



Starters aren't too bad. They're heavy but if you have studs instead of nuts you're laughing when it comes to installing it.

 

Starter burned up on my T660 a while back and I helped the mobile mechanic replace it. 3 main bolts, the bottom one was the worst, took both of us pulling on the ratchet extension to break it loose. Original starter and the bolts had been in there about 6 + years. Bolt came out with clogged up threads where it took some of the material from the block. While mechanic was gone I chased all the holes with a bolt chaser and we put the bolts in a vice and chased those with a nut chaser then slathered the bolts with never sieze stuff and reinstalled. To keep the wiring straight, we put color coded zip ties on each on so the hooked back up to the correct way.

 

I take the ground wires off with a zip tie in my hand run it through eyelet. Do the same for positive wires. That way you are sure these go together and those go together. A small one isn't separated and over looked etc.

 

Make sure you don't miss the wire from the negative terminal to the block, and don't be cheap with the anti-sieze either.
