Smile 3G alternator upgrade

'85 6.9 F350. Just wondering what's all involved with this and where to get this famed alternator and anything else I might need. Thanks!

Here is a good thread on the 3G Alternators. There is a lot of threads on this upgrade.

In this thread is a list of vehicles you can get the parts off of at the PNP type yards.

Thanks, I try to help. Iam still learning from the others before me.

I have been going to do the 3G upgrade, just too many other things get first priority.
Have owned this 86 7.5 years and on the 3rd G1 Alternator, this present one has
run 4 years and 70K miles.
Last time I changed it out, got it from O`Reilly`s, and working with the MGR, went
through 3 to find one w/o dry bearings, right out of the box.
Right after I changed it, found one at PNP in a 6.9 that was just replaced, wasn`t
even dusty was so new . Another G1.

So you never know what you will find in the yards poking around, wish it was a G3.


Charlie

Sorry about your luck Charlie. In my opinion just order a new 3G and be done with it.
