Missing Transfer Case Bracket Insulator Retainers

[Elwood]

I'm finishing up the details on the NP200 transfer case that I rebuilt, and noticed an item in the ORD 9 SNL that has me puzzled. Part No. G505-0638124 (Chrysler p/n CC-690347) is listed as a "RETAINER, mounting bracket insulator" in section 0800, Transfer Assembly, quantity four (4) required. But I've never seen one, my truck didn't have them when I disassembled it, and none of the vendors' catalogs that I've read show it. The "G505" prefix means that the part originated with the earlier Dodge WC series of 1/2-ton trucks.

This part does not appear in the later (1972) TM9-2320-212-34P parts catalog, either.

It's apparently used as part of the rear motor mount assembly for flathead six Dodge and Plymouth cars, and I suspect it's some sort of metal cup to control deformation of the rubber isolator used in the mount.

The only possible illustration of these retainers that I've found is Fig. 163 in TM9-8030 Operation and Organizational Maintenance manual:



If you look closely, there appear to be upside down shallow cups on top of each of the lower insulators (the ones underneath the transfer case mounting brackets) between the insulator and the transfer case mounting bracket. The text on how to install the transfer case onto the truck's frame that goes with this illustration makes no mention of these retainers, however.

Elwood,
Mine were welded to the T-case bracket. Is yours flat?

Look here:

They are in the photo in the end where I was filling the T-case. You can see the yellow strap that's passed through them.

Andy, I don't recall. I'm not at my shop at the moment, so I can't look at them, but I don't remember that they did.

Typically, when a part includes other parts that are available separately, the ORD 9 SNL will refer to it as an "ass'y", and include the other part name(s) in all caps in the description. The transfer mounting brackets descriptions only include "INSULATOR", but not "RETAINER".

this piece is easily made with a washer and a bit of pipe. if you want to pay you can check out vps new catalog T case page #4 https://drive.google.com/file/d/0BxzO_O ... 4zM3c/view

Thanks, RMS, but I think you're referring to the "SPACER", which is p/n CC-1268339?

It is a large "fender" washer brazed to a tube. The length of the tube sets the amount of crush when you tighten the mounting bolts. I don't have a spare out to measure, but someone here surely will.

That part is welded to the mount.

[just me]

It wasn't hard to remove to measure.
It is a 7/16 fine thread bolt 2.25" long.
The spacer is a flat washer 2.5" diameter .100" thick brazed to a steel tube .635" OD, .450" ID by 2.300" OAL.
I can't post pictures here but will post one on the Facebook m37 page.

(My bad. Poor reading comprehension. That part is welded to the brackets on mine, also. 4 locations. I measured the spacers.)

Thanks for all of the replies, photos, and measurements, guys.

I was able to check my transfer mounting brackets, and sure enough, they have those rings welded on the undersides. I guess I was reading the description in the parts book as being a different part, since there was no mention of an assembly or "welded", which is typical in that manual for parts with different part numbers that are welded together.
