92/93 Superliner drive axle

[FarnorthMN]

Good morning guys!   Can anyone help me with axel seal and hub specs.  Vent plugged up causing wheel seal to leak.  Does anyone have or know the spec. for wheel seal depth in axel hub.  And what should the hub end play/oil clearance be when setting wheel bearing?   its on a 85 RW613 Superliner. 

Thank you!

Looks like someone had Stemco "grit guard" seals on that one. Also looks like the shoe pins need to be replaced/ freed up before that becomes a big task. They already look "frozen" into the spider.

Need to knock the "wedding band" off the spindle before putting a new seal on.

Since you have the old seal, look on it for the seal number.

the wear ring has a 4 digit part number on the back side. I will lead you to the correct Stemco seal kit. The wear ring is installed with a special tool. I suggest looking at the spindle to make sure there is not a groove worn into it. If no groove is present, you can cross reference the seal you have to a voyager series that doesnt require a special tool to install, just be cautious. 

I see the blue seal is removed. you can look inside the seal for its 4 digit part number as well.  Of course if you are like me, i always end up putting the prybar right on the seal number.. 🫣

Thanks guys I was able to get the right stemco seal and wear ring and I have a steamco seal drive but not the ware ring driver.  Just wondering if the seal bottoms out on the inner shoulder ware my finger is?  im assuming it does. @Joey Mack

Yes if it doesnt have a flange.  When you install the wear ring, be sure to put a light bead of RTV on the leading edge so that it spreads the RTV as you drift the wear ring on. It stops when flush with the spindle. Then wipe off the excess RTV once its seated. The fancy tool does a perfect installation.

here is the tool. then you have to buy the correct installer head for the wear ring. It is designed to slide snuggly over the spindle , while keeping the wear ring straight and it doesnt mash the end of the wear ring too.  the tool numbers are on the stemco seal box.

Im not trying to make this a big deal, just showing you what is out there for proper tools.

awsome thanks again @Joey Mack that is what I assumed, but you know what happens when you start assuming things...   Hub end end play when setting wheels bearing .001-.005 is kinda what I have always been taught. does that sound about right? 

[FarnorthMN]

@Geoff Weeks yep I think your right that was my next step before anything.  just wanted yo make sure I get what i needed for the wheel seal ordered.   thank you sir!

if you are asking about bearing clearence, what we always did was.... preload the bearing at 200 lbft, then back it off, and set it at 50 lbft. to engage the lock ring on the dowel will sometimes require you to turn the inner nut a little. you can flip the ring over to see which hole is closest with out disturbing the final torque too much. I always choose to back the nut off a small amount instead of going too tight. 

does this post make sense?

[Joey Mack]

I forgot to say, the outer axle nuts gets put on with a large breaker bar as tight as you can get it. I think it is about 550 lbft. 

[FarnorthMN]

yep that makes complete sense.  So essentially the wheel bearings will have a preload of 50 ftlb give or take dowl alignment? 

[Joey Mack]

yes. the dowel location is not clocked to any certain degree. Many times after doing a zillion of these, when I back it off then set it to 50 lbft. the lock ring is lined right up to the dowel on one side or the other. it will be very close, half a hole off.. but dont sweat it if it is a full hole off anf you need to turn the inner nut to line it up. be sure that the dowel is in the ring hole so you dont jam the 2 nuts together and mash the dowel.. The wheel bearing will loosen up on it's own.
