85 2wd C&C Dump 4x4 Conversion

[Weberman]

Idk if you still need to know, I slightly skimmed and saw that you got a yoke BUT my NP208 and 1345 yokes did interchange. Same height, same diameter. I had a 208 in my Bronco and it went out. It came with a 1345 when I bought it but the rear yoke was different. I tried to take my old yoke off and swap, didn't go. Noticed the splines were square instead of tapered and 31 instead of 32. (Recently from messing around with yokes after I got another transfer case, I found out that the 1345 that came with the Bronco had 31 square splines on the rear and the 32 tapered splines on the front. No idea why they're different.) I bought another 1345 that still didn't bolt up but the rear double cardan BUT took the yoke off and it had 32 tapered just like the NP208. I swapped them out and good to go.

This is why I keep saying it is all about application.

There are dozens of variants, depending on which manufacturer and model the transfer case was intended for.

Shafts won't swap between  models and manufacturers but a 1345 could be found in anything from a Bronco to a dump truck.
Slip, fixed or flange yokes. Different shaft diameters and spline counts.
And then Spicer has to come up with whatever goes in between.

Anyway, it looks closer every day.

All very true.  I will not allege to know much about anything, but I do know the yoke I got was listed a "1330 Series CV Yoke for 203/205 front output T Case yoke" and it does fit my 1345. I realize there are aspects of that front output "shafts" between those two transfer cases that are different, but what sticks out of the transfer case that the yoke connects to must be the same (at least between my specific 1345 and a NP 203/205).

I also know Shawn (at Tom Wood's Custom Driveshafts) was very glad that I had a 32 spline. He insinuated 31 spline situations are not favorable for the double cardan application.

Weberman-  To be clear, are you talking specifically about rear outputs/yokes on Bronco application?  Just wondering for reference.

Wish I could post a video... There have been a lot of triumphs in this little project been hearing her run sounded pretty doggone good!

Sure sounds good from here too!  

[Gary Lewis]

Yes!  I intended to say that in my post but forgot.

[bp17oang]

Not too shabby

[ArdWrknTrk]

Looking gooood!  

I don't think you would budge those springs with the dump you have on there.
Do you intend a utility box or anything else on that step you have?

[bp17oang]

Yes I'm going to put one on it. There was one on it but it was rotted out

It would take a lot. The helpers aren't even touching the perches.

[ArdWrknTrk]

The great thing is it is under it's own power and ready to earn it's keep!

Congratulations.

Thank you... Everyone, for all your help and advice! Amazing group of guys. I've wanted a straight axle bullnose since I saw a crew cab with one 20 years ago. Now I have one... That I (and my daughter in the shop many hours) built!

Still have some things to tidy up, 3g alternator, utility box, a few wiring bugs, some interior stuff, and a set of tires...

I know it's not the end of the project but it sure is cool to drive her out of the shop!! 🍻

Got my hands on a 3g alternator and wiring harness yesterday. The alternator appears to have been remanned and not used much ($50 for the pair! ).  I didn't think it had any type of circuit protection but when I pull the wire loom off the end there is a fusable link.

The alternator I got is 130A small frame but it has the 10mm hole on the tab for the tensioner bracket.  Thus, it is too big to tap 3/8 16.  Does anyone see any reason I cannot just use the 3/8 bolt with a washer, lock washer and nut here?

For the record, the alternator was tagged indicating it was off a 2000 Taurus.  The wiring harness was off a 95 F series.

[ArdWrknTrk]

You can use a nut & bolt, but I usually Helicoil those later alternators,
because I find it too challenging to hold tension with a pry bar and use two 9/16 combination wrenches.

Small housing or narrow mount???

Small housing (135mm) would be the four hole 95A alternator.

7" C-C mount is from the 3.0l V-6

[bp17oang]

Yes, I misspoke... large housing with the narrower 7" hole mount.

Fair point on the helicoil vs bolt...

Thanks for the tip

Any thoughts, part numbers or other tips for running the 3G with dual v belts?

My current setup has a crank pulley with four sheaves. Unfortunately the two outer (closest to the front) sheaves are different sizes which are the ones that line up with my 3G alternator.

The other 460 has a three sheave crank pulley.  

Thanks

Gary was looking into this before he decided to go with a polygroove front dress.

Perhaps he has some numbers for the front crank pulleys?

I have been using mine with a single belt and it's been fine with a Load Response Control regulator.
