Starter ?

Will a 7.3PSD starter work on a 7.3IDI?

I dont think it will, in my books they look like to completly diff starters

The PSD starter will work. BUT it has its advantages and drawbacks. Advantage...if you have a damaged teeth on the ring gear the PSD starter is good.
Disadvantage.....this starter is very sensitive to voltage drop. If you battery voltage drops and you are still cranking at 11.5 volts, the internals will melt down quickly.
suggestion......stick with the mitsu starter(one with a nosecone) unless you have ring gear issues.

The IDI starter has 13 teeth which spins faster. PSD spins slower.

So I take it, the starter will physically fit, but it spins slower. possibly requiring longer crank time thus leading to possible internal damage due to extended cranking time. Right?

sorry about that i was looking at the 6.0L starter

Would put a strain on the batteries as well due to longer cranking time and cold weather may pose a problem.

Thanks for all of the replies.

i thought i remember reading on ebay where the PSD starter had 12 teeth instead of 13.

Yup, it's confirmed, http://cgi.ebay.com/ebaymotors/ws/e...tem=7966811731&category=33576&sspagename=WDVW

12 teeth.

12 teeth.

Wouldn't that make the PSD spin faster? Or do I have my drive gear info backwards? I guess all of that depends on the flywheel or ring gear.

Is taht why the PSDs take so much longer to start than an IDI? Calvin, this info sounds just like what you said about the Nippon-Denso starters, are they and the PSD starter one and the same thing? I'm very happy with my Mistubishi starter, had it in about a year, and had some hard cranks in that time, lots of starts, no issues.

I recall someone once saying that PSD's take a relatively long time to start 'cause the engine won't start until there's enough oil pressure present to make the HEUI injectors work...so the engine has to crank until ol pressure builds up before she'll even light off.

I may be remembering it wrong, though...

U hit it right on the nail warden they need oil pressure to opperate the injectors
