Do these starters in these trucks last as long as a gas engine starter or does the fact turning the engine requires more grunt burn them out faster ?


The reason I ask is because it seems like I have to replace these more often than a gasser.

 

Yes. They use a lot of cranking amps and get hot as hell. You can make them last by keeping your crank times down and let the starter cool for a minute

 

The Ford recommendation is 20 seconds of cranking 2 minute cool down.

The biggest difference in starters is Direct drive versus Gear drive.

You want a gear drive, not a direct drive.

Thanks, so the trick is to make sure your fuel system and glow plugs are right and the starter will last......

 

The real problem is that there are a lot of really crummy rebuilds out there; it's a crapshoot what you'll get at the autoparts store. One might last a month(due to poor machining of the brush contacts eating the brushes up), while the next might last years.

Also, our trucks have a standard SAE #2(IIRC) starter pattern, so you'll find starters from other engines which fit. As long as it's a gear-reduction unit of the right physical size, it'll probably work.

On top of all that, Realslow has the right idea here: My tan 88 will fire off in about 5 seconds, with proper glow plug use. My blue 88 takes about 20 seconds of cranking(and two cyclings of glow plugs), due to a worn out IP and possible fuel bleed down(and probably other issues). Which do you think will have a longer lasting starter?

 

true true .. my orylies starters with lifetime warranty are shotty rebuilds .. keep the receipt

the brushes are ok in the second one .. but poor machined nose gears .. cutoff wheel repaired and it works good now ..

always cranks 2 seconds only with tiny spirt ether and zero working glowplugs

 

I do not like glow plugs but I live in the south but people up north say you have to have them.


I have read where people will install ether injection on these but when I use ether the engine tries to fire backwards.


Does anybody have a solution to this?

 

Means you're adding too much. Found that out myself. Just a whiff!
I personally hate ether. I think it's garbage on these high compression diesels. Modern ones works great for but these ones are way too touchy about it.
I recently found that gasoline in a spray bottle works REALLY REALLY well and won't pre-detonate. Was trying to bleed my IP after a swap and it will actually run the engine around idle speed or a bit faster if you pump fast enough, haha. Bled the injectors in just 10 seconds!!!

And to stay on topic...it's also really really easy on the starter.

^^Keeping it on track haha!

 

I went through four Mitsubishi starters in less than a year, got a denso and its made it a year so far. Even whips over like a powerstroke. Something none of my Mitsubishi starters would do. Maybe I just got duds. None of them actually died. They just began to drag. I'm hell on starters though. With a lifetime warranty I don't cut them any slack.

 

The best answer so far.

 

A 400$ starter? I'll pass

 

I have the gear reduction atarter from NAPA and it's been lasting me for number of years with no problems

 

Yeah! The Denso was $280 with a $120 core charge so I only payed $160 n change all said and done. So far so good
