Starter Problems ?? Read Here !!

Hi, I've gone through a few problems regarding my starters...

It all started with my stock starter loosing power, it just would not turn the engine over, even with plenty of charge in the batteries, it would click but would not spin...

So I ordered a new one... why buy expensive when I can get one for no Money at all from USAutoparts (155$) ?

Part Number MPA17801N

"GMC Sierra 2500 HD Quality-Built Starter"

No longer for sale (removed after I complained and received a new one), but I suppose what I found could be applicable to other low cost starters as well..


My problem was: It turned the engine over like nobody's business but started to grind it's gears, made a horrible sound, and I thought OK, I need a new flywheel\starter ring gear..

But no.. I checked it, it looked absolutely fine...

I complained and USAutoparts sent me a new one.

Now I searched the web, and found others with similar problems, but no real explanation..

I started to compare stock vs new starter... Visually they looked almost identical...

Problem is shown here:

cheap US Autoparts starter:



Stock Isuzu:



See the difference ?

A 2.3mm difference in gear width..

I also pulled the gear out as far as it would go, that's maximum excursion, it was about 22 mm on the cheap one, and 24.5 on the stock starter..

So the gear engages 2.5 mm less with the cheap starter than it does with the stock one.

Not much, but enough to make it grind ?

Also, the stock one had all metal parts inside, where as the cheap one had a lot of plastic parts, the solenoid design looked a lot better on the stock one as well..

I will try a shop in Murmansk Russia that a friend of mine mentioned, (I live right next to the border) I think the entire problem is a bad solenoid, (Might also be the wiring from the solenoid to the starter itself, as the wire was partly melted) the brushes in the starter looked fine.. So did the reduction gears and the contractors on the stator.

Yeah its always better to rebuild the original when its an option. And its usually cheaper with starters and alternators too. Glad to see you got a refund as well.

Personally I always buy Alternators from www.dcpowerinc.com

Now I have a 270a alternator that delivers 170a at idle
Makes a HUGE difference, and insures fully charged batteries even after a short trip..

Not to mention it powers my huge stereo system.
