(TOM) D300 pics/info

[UnkleMunky]

With the talk of Dana 300s out of CJs and such, thought this link would be interesting for anyone to look at:

http://cgi.ebay.com/ebaymotors/aw-cgi/ebayISAPI.dll?ViewItem&item=597816394&r=0&t=0

It's an ebay auction item for one of them from a CJ. Gives some good pics, which is nice to see.

BTW...only 1980 model Scouts carried a D300, so they are quite rare in the IHs!

Not an expert on them, but thought this a good page to look at it.

Enjoy

If, you found a Scout D300, do they bolt up, or do ya need to swap parts or an adapter.

I've got a D300 I'm going to put behind my NV4500. I would have bought that one for a spare for $100 with the shifter, that was a good deal.

Not trying to confuser you, but here's a ton of information:

Jeep Transfer Case: Dana 300

The Dana 300 is a heavy duty gear driven transfer case that takes a 23 spline input shaft. The case is cast iron with a number C300-15 and the tail housing is aluminum. The output for the front driveshaft on the Dana 300 is on the passenger side and the rear output is centered. Low range is 2.62:1 and high is 1.00:1.

The bolt pattern is the same as many New Process transfer cases, but the drop is on the opposite side. Most New Process transfer cases used on Jeeps have the round bolt pattern and 23 spline input so it is compatible to some extent. The difference is all the New Process transfer cases are drivers drop and the Dana 300 is passenger drop. Some drilling and or tapping may be necessary may be necessary in the transfer case or the adapter to "clock" the transfer case. One bolt hole in the pattern is offset to allow the transfer cases to only be bolted on one way. The other option is to not use the bolt that clocks the transfer case.

One way people modify the Dana 300 is by adding oil paddles to the main shaft. The oil paddles prevent oil starvation of the rear bearing when flat towing. Another possible modification to the Dana 300 is converting it to u-bolt yokes rather than strap yokes.

Usage
The Dana 300 was used only in CJs from 1980 until 1986. The first year the Dana 300 was available there was a slight difference from transfercases used in '81-'86 CJs. The 1980 Dana 300 features a shorter tail housing which allows a slightly longer rear driveshaft.

This is from the Off-road pages. I couldn't find the page for this, so pulled it off my saved information. They do still have the Scout D300 page though:

If that doesn't keep ya busy, don't know what will. Looks like the Scout300 will work where a D20 or D18 was, but a Jeep300 will go in where a NP case was(only these were pass. drop versus the rest of the NPs in Jeeps, which are driv. drop). Then, there's the gearing and that most of this info is aimed at CJs(what else is new?), where tailshafts were often different lengths. Fun, fun, fun.

Hope this fills in even more. I liked the pics on ebay...that was nice to see.

Take care...
