Does anybody have the part# for the small seal that fits on the shift shaft of the 2 speed transfer case. the one that goes on the shaft that attaches to the shift fork? I looked through this thread and I couldn't find a reference to it.

[Bob Carriere]

Hi Harry

Was at a seal wholesaler today and they still prefer to search by OD/ID since numbers vary from manufacturer and over time..... once found they give you a choice of made by 'who' where (time) and/ or shipping cost.

You can probably figure out the ID easy enough but it will be a hell of a tight fit to measure the OD without taking your T case out....

Any body on the forum that has a 2 speed already taken apart for measuring....
I would suspect that the size for the two rods on the 2 speed and the one speed T case are the same...... need some time to read and compare in the parts manual..........

Mine where tight when I rebuilt my t case...... one of the few parts I did not have to change.

Good luck

[Harry Moon]

This shaft is only on the 2 speed, and its apart on the bench.

[Hanno Spoelstra]

Harry, if you can measure the shaft diameter and bore, go to http://www2.chicago-rawhide.com/ and click on "Seals North America Part Lookup".

Entering the ID and OD will give you a match from the current SKF seal catalogue, which in turn can be crossmatched to other manufacturers.

HTH,
Hanno

It is the best advice to replace the original seal 50300 with two CR19360?

I put 2 in and it seems good.

In building up the big 6 inch front axle with the big brakes I found the BH5931 hoses to short to cover the range of movement. I sourced BH6222 and they are the same length as the originals and have the same 5/8 thread end as well. I would recomend these be added to the parts list for 6 inch axles and they would be fine on a 5 inch axle as well..

[Jordan Baker]

In the 5” or 6” axle. What is being measured to determine those sizes? Was one used on the 15cwt trucks?

[Bob Carriere]

You can tell the 5 from the 6 from the flange cross section diameter....6 also has more bolts on the flange an the six has 6 bolts holding the top cap where the new departure bearing is located.......small C15a larger on C60 but there are exceptions Aussie C60 made in Canada late in the war has small axles and 16 in tires.

[Jordan Baker]

Thanks. I see the differences now. And with 7min to spare I learned something new today.

[Harry Moon]

the easiest way to spot the 6 inch front axle with the larger brakes from the regular 5 inch front axle is at the hub. you can see the obvious bulge behind the lift ring on the 6 inch. not so obvious is that the wheel base is wider by a couple of inch's.
Soi far I have only seen the bigger 6 inch on FAT's and winch trucks.

[Harry Moon]

Somewhere in the past there had to have been a Wagner/Raybestos/Delco part number for the original master cylinder. Anybody have that information? Might be useful in checking out old NOS stock we sometimes come across.

[Jon Bradshaw]

So I just pulled the seals out of my transfer case and they all appear to be the same size. One was so bad that the oil could have been drained out the gap instead of the drain hole.....
Two of them have a paper gasket behind the plate and they are in bad shape. The input one has a steel gasket in place and no paper ones. Any ideas on sourcing these paper gaskets?
The steel one looks fine although I am unsure if it would work without a paper one as well? If it was aluminum or copper I could see it being a crush type but it is definitely steel (has rust).
Thoughts on the gaskets? Should I just try to cut my own?

[Jordan Baker]

I believe the steel one to be a shim. In the MB-C2 manual there is a very good detailed write up on the servicing and rebuilding of the transfer cases.

[Jordan Baker]

Does anyone have a source for the through bolts used on these brass blocks and for the rear brake one? All of mine were rusted junk. Are the front ones the same as the rear ones?

NAPA has them complete with or without washers. You just need to know your thread size (usually 7/16-20 on most of the old North American stuff). Use the term "Banjo" bolt when talking to the (oldest) parts guy. I find the younger parts guys go crosseyed when you use common terms like this.

If you lived closer, I have a bin of about 50 of them out in the shed.

[Jordan Baker]

Ok great. I just wasn’t sure as there seemed to be different ones. I’ve got an old school NAPA in town. I’ll go visit them tomorrow.

[Jordan Baker]

Not truly a modern part but these are measurements from NOS felt seals used in the steering knuckles.

These are for the 6” ones but are the same for the 5” axles except in overall length.

The length is 24-1/2”

Hi Jordan

Thanks, good information to add to CMP Knowledge Base.

I've been using leather replacements since 1979 back then it was really hard to get information on CMPs. My first discussions with anybody who could answer questions was via regular mail. The first responses I got were from guys in Australia and New Zealand.

Cheers Phil

Good Day,

Here's another seal number that fits the Ford transmission rear seal to add to CR 21211

KOK brand Part No. TC 12167, rubber covered. They conveniently even give the dimensions embossed on the seal, in inches no less! KOK is a Taiwanese company so probably available worldwide. Cost $10 at the local bearing shop in Australia.

Cheers,

[Hanno Spoelstra]

Ian found out the hard way (= buying the wrong seal), that the Ford F15A seal front hub inner 5", Ford part number C01Q-1190B matches with SKF/ CR 49998 with ID 5" and OD 6.25"

[Jacques Reed]

Hi Hanno,

It is easy enough to do, get the wrong part, I have a box or two of them, but measurements in the case of seals are the only true way to go. Even then, take the sample and, if possible, the part it is intended to fit to the shop. I did that with the rear transmission mount and seal and the bearing dealer confirmed my measurements.

Of course, in these days of mail order only without bricks and mortar shops it is often hard to compare parts.

I downloaded the CR Seals Handbook (SKF) and it is a wealth of information besides listing available sizes of seals and Speedi Sleeves. Recommended download for any restorer of any vehicle.

Cheers,

[Tony Smith]

Where did Ian's info come from? Was it the .zip file I posted in Post #10 on page 1, or is there another table? I no longer have Excel on my computer so can't read that table, but Keith's post #19 still has that info brought across on his webpage and it clearly shows C01Q-1190B to be a 5" seal and part number 49998. Where has the conflicting info come from?

Hi Tony,

Going back through the releated threads the correct info was there indeed, but I did not help with muddling it up. The p/n I shared is correct for the seal with the dimensions shown, but that seal does not cross reference to C01Q-1190B. It now turns out I was wrongly informed and have been sold the wrong seal as as well...

Anyway, I have offered compensation and invited Ian to add his lessons-learned to this thread.

Ford master brake cylinder, 1 1/4" bore: current part number of a Rebuild Kit is 91T-2004-A, 91T-2004.



These kits seem to be quite easy to source in the USA, Canada and the UK, but I could not find a rebuild kit closer to home - until I remembered this:

As Dodges are very common here in The Netherlands it was much easier to buy a rebuild kit off the shelf, e.g. at Staman Trading:

Applicable to the Otter, C15TA and I believe the Fox AC and C60X transmission.

I had to do a rear U-joint on an artillery tractor (Chev) a couple days ago and found the U joint that was commonly referred to on MLU was too short. The U joint referred to equals a UJ331 (the 331 is a common reference and the spicer number is 5-1350x). Caps are 1.188 diameter and the height is 3.622

A little research led to the right U-joint. The caps are 1.188 diameter and the height from top to bottom on the caps is 4.187. They are spicer 1410 series U joints and use part number 5-1410X. Another common trade number is UJ330.

It may be that the number listed on MLU is for the smaller or earlier trucks. But the various cab13 shafts I have sitting here all appear to use the latter UJ330 (spicer 5-1410X) U-joint.

[Jordan Baker]

Rob, these are the parts I had a heavy truck shop tell me where the same as what I brought in from my C15a truck.
