M939 Axle stub "RING - WIPER" installation tool?

[Wile E. Coyote]

Doing a couple of rear axle inner oil seal replacements on an M923 and the surface the oil seal rides on is badly grooved, so I want to replace what most of us would call the existing Speedi Sleeve - but which the Army calls "RING - WIPER, 2590-00-740-9553". Anyway, found a great deal on the sleeve itself, but nobody seems to have the "SEAL INSERTER - 5120-00-795-0136" you really should have to install it. I've put Speedi Sleeves on before and they're a bitch without the installer tool, so:

a) does anyone have one they care to sell, or know where to get one?
b) what are other owners using instead of the tool?

I've made tools up before out of various things but at the moment I don't have a lot of time to play around with fabbing up stuff like that.

we used a hand grinder to remove the old ring, we thinned the ring to a blue, then used a small custom ground chisel to go between the ring and the spindle, spliting the ring, dressed up the spindle with fine emery cloth,

You can heat them in boiling water for about 20-40 seconds, get them hot but you have to be careful not to get to hot. The key was I had what I believe was an old PVC toilet flange that fit perfectly. You heated up the ring, put on fast and then put the pvc flange over and drive it on with a small 3lbs hammer.

Get an extra ring or 2 in case you mess up putting them on. Take the ring to your favorite hardware store and find the right size PVC flange and you are golden.

4" abs drain pipe with a coupler on it works great to drive them on.

I am not sure if you already bought the new seals, but if you haven't yet, you could go with either National or CR "unitized" seals and get away from the old single lip seal and wear ring assembly.

Do you have a part number for that?

Ha. That's hilarious, because my 2 am problem-solving-half-asleep-mode mind also thought there might be some PVC out there about the right diameter The boiling water tip is great - never considered that. It made sense to heat them in some fashion but SKF basically screams it from the rooftops on their website not to heat them up (though I think they're picturing people doing it with an open flame propane torch which would indeed distort/ weaken the thinner varieties...like the virtual...tin foil...ones you get with the CUCV harmonic balancer sleeve kits.)

I had made up my mind to order a bunch of them in case I mess up. Sounds like something you'd be lucky to nail on the first try.

I think I only messed up one hit the shaft with some sandpaper before you put these on so you have a smooth even surface. I think 162Tcat hit the adapter on the head, no pun intended!!!!

Take some pictures of the install, I forgot

Will post seal PN's tomorrow.

The unitized style seal SKF (CR) PN is 47660 and the National PN is 370051A. I have had good luck with both of these in the drive axles (M936). If you haven't installed this type of seal before, read the manufacturer's install procedures...this style of seal is not installed like the steel cased lip type. I cannot say how these seals will perform during fording ops, but they are definitely far superior to the old style for keeping gear oil in the hub.

Do believe going to CR47660 you still have to run the ring / wiper
Removal was easy for me just used long brass rod and tapped the backside lightely with a hammer.
Also the ring wiper is like 10 bucks from military supply and the speedi sleeve is 60 bucks .
