Starter turning slow

[lcattin]

I have a 1999 Dodge 1 ton Cummins with 2002 engine showing 365K on the ODO.

 

The starter seems to be spinning too slow. 

Voltage regulator was out on the alternator so that was replaced. 

Batteries were 4 years old and store checked them failing their testing so they were replaced.

The starter speed hasn't changed with the new alternator and batteries.

 

The question is, do I get a reman starter from O'Reilly or AZ,  or rebuild the starter that I have?

 

The rebuild kit would be a little cheaper but more labor intensive.

 

Please weigh in with you opinions on the best way to go.

 

Thanks,

Les

Rebuild. Larry B has a better than stock rebuild kit. @Mopar1973Man is the rebuild kit in the store?

Rebuild is simple. If we don’t have a kit here genos and others have them.

Sorry no. We don't have any start rebuild kits in the store...

Thanks for the help guys.

 

I ran across the Larry B website the other day so now I know that is the way to go.

Just a thought but have you checked the electrical connections and wires?  Maybe old and corroded and not giving you the power you need.

I see I'm late to the party and you already made right choice, contact and plunger kit usually does the trick. And yes very easy to do.

Starter spinning to slow could be bad field windings

 

I had a year old napa starter that was spinning slow with new bats. Pulled the starter and napa tested it. Drawing to much amps/bad or broken field windings.

 

Napa gave me another new starter free . warranty

 

I should have kept my factory Denso starter

My factory Denso left me about 11 years ago. Did not know at the time how easy they were to fix

[lcattin]

If I remove the starter how can I tell if it is original Denso or Cummins?

[lcattin]

Ok. Re-tightened the connections and not much help. Also found the tag that showed that it is a Denso. Time for rebuild.

If the starter turning slow, and since you're in there, you might as well get the brush kit.  I recommend a small torch to do the soldering of the brush leads, rather than a soldering iron, you'll be waiting forever for it to flow.  Try to protect the brush sleeve with some fiberglass or aluminum foil.  Also, that old phenolic lead to the solenoid is very brittle by now, snapped mine right off trying to remove the wire.

File too large

[lcattin]

Thanks for the tips.

 

I have it removed and torn down. It is really dirty inside and I think the brushes are sticking a bit so I ordered the Larry B kit with brush kit included. I don't think this starter has ever been apart in 365K miles. Should take of things.

 

I'll update when I get it done.

Got the starter kit with contacts and brushes today and got it rebuilt and installed. This truck has never cranked over this fast in the 4 years I have owned it.

 

Thanks to everyone who offered advice and guidance to help me get this done.

 

Now all I have to do is change the heater core. That's for another day.?

How hard are they to rebuild?

Been there done that many times...

Good to hear she's cranking again.

It was easy to rebuild. I used a Weller gun to solder the brush leads in.
