Rod, I know what we have seen on these seals, but Wleit and Crankshaft45 are correct, according to TM 9-2320-246-34, "Position first plain encased seal, lip end in, on shift shaft, being careful not to injure lip of seal. Position second seal on shaft, lip end out." The last few seals that I have replaced, I installed the new ones this way. It makes more sense, the inner seal seals the transmission oil in and the outer seal seals out dirt and water

Of all the shift shaft seals I have replaced, only 2 mules had the seals installed as described in the TM.

Guys,
That's what is great about these forums, it is a place for us to share what works well for each. The way I put seals in works for me. Yours maybe different.

I can not think of a mule I have worked on which had the seals installed the way the TM shows.

Each to their own...

I know, I've only seen 1 or 2 and I thought they had just been installed wrong! I'm looking through my literature to see of there ever was an MSO or something issued about these seals, too many of them are installed "wrong" for it to just be a mistake.

Yes, that's the way I put mine in. On facing in and one facing out. Figured it was to keep out water and dirt as well as oil in.
Working good so far but always interested in how others fare.
One of them YMMV things I guess (Your Mileage May Vary)
Best to all,

Just finished mine and i did it like the book, one facing out the second in, but that's how they came out too. I was wondering what would happen if you just put one in, if you had no plans in running through a swamp. Oh, well, on to the last item (next Spring): changing the brake shoes and finding out what is causing a nagging drip from the drum when it's in all but one position (which i've marked on the drum and park the Mule with the mark in the 9 0'clock position to keep it from leaking about a teaspoon a day). Now that it's done, i'm getting ready to haul logs to the Central Boiler and can't wait to check out the weight dragging abilities. Crossing my fingers!

Mike,

Have you used this puller on the Mule shifter seals? The reason I ask is one of the semi - local Napa stores has it it stock but it is a 32 mile round trip. Wanted to be sure before I made the trip.

At that price, grab a couple of them and I'll buy one from you next time I see you, mine is worn out!

Guys

One thing to note I did this with a very worn out puller from the Transmission shop (different from a tranny shop) across the street. I could only get the outters removed. So in my infinate wisdom (or lack there of) I just replaced the outter seals thinking, "how bad could it leak",,, AAHHHHHHH Bad, now I get to do it again..

Just went through shaft seal replacement on my A5. Had purchased one of the GM seal pullers online SST version. Pulled first outer seal with tool and the tapered threads, which grab the seal, ended up damaged and would not thread into the next seal. Threads are cut very shallow and not hardened. I ordered up the SP 96480 puller. What a difference in the thread design. Much more aggressive. Removed the remaining 5 seals and tool showed no wear or damage to the threads. I did need to get a longer 3/8 center puller bolt as the SP puller is much longer than the SST. Length of supplied bolt was not long enough to contact shifter rod and pull seal. A quick trip to store for new 3.5" bolt. Just have to have a full length threaded bolt. Ended up with a carriage head bolt. Used square shoulder under head for turning with crescent wrench. Works great. Note it may take two tries with puller to remove outer reversed seal. I found the first attempt pulled the rubber lip seal off the steel main body. Got that out of the way, threaded puller into remaining steel body and pulled it out easily. Used a deep socket to reinstall new seals as its' OD much closer to seal OD than the SP supplied installer. Be careful installing reversed outer seal. Since it is backwards you do not have a good flat area to drive it back in (only the seal outer shoulder). Found a small piece of flat steel, drilled hole in center for shifter shaft, placed over shaft, and the tapped in with deep socket.

The new plastic seals are a tad taller in height than the original metal Victor seals. But they went in nicely.
