New York bound with wheel seal woes - plus VMSPC screen shot

Try some Lucas wheel seal stop leak before you replace the seal again. It worked for me, keep some in the coach all the time. You can get it at the truck stops.

What engine do you have in the coach and is the silver leaf showing the correct fuel usage?

How do you make a SilverLeaf read the correct MPG ? I have the 3.B2 version I have worked with Art @ SliverLeaf he has not made it read accurate yet it shows I get 8.3 mpg but using the pencil with miles traveled and gals used I always come up with 7.2 mpg on the 60 series

Hey Jack - great idea. I'll give that a try first as it sounds like a cheap and simple fix if it works.

The engine is a year 2000 Cummins ISM set at 400 hp. It runs through a Eaton Auto Shift (Gen 1). The mileage is correct within a a tenth of a percent every time. I hand calculate the mileage every trip as well. It is generally off on the high side, never on the low side.

Clifford - I haven't tweaked anything with my installation. However, I do know it is reading miles very close to what my odometer reads which is very close to what a GPS reads. So, miles traveled is pretty accurate. Fuel usage is generally pretty good as well. So - maybe there is something about how the Series 60 calculates fuel usage or the tire size/differential ratio/transmission ratios are not entered correctly in the DDEC so that distance traveled is not accurate?

Just how full did you have that hub?

That could be it Brian the engine was 400 hp a MCI factory setting I bumped it up to 470 hp it make take a little tweaking on my end

I had the oil about 1/2" up the clear plastic. This meant filled almost up to the filler hole.

Over filled.

Ed Hackenbruch · May 20, 2015, 07:15:31 AM

If you look very closely at the plastic part you will find in small print where the correct fill level is.....you might need reading glasses to see it.

So - will being overfilled cause what I described?

in my experience, it is pretty hard to overfill them. i think stemco pretty much calculated the maximum amount of oil that one can put in there, there are quite a few different hubs and caps in their catalog for different applications. 3/4 inch and 1 1/8 comes to mind.
if the fill mark was the only acceptable level, they would all have the bigger cap.< in other words they are pretty much idiot proofed (That is a figure of speech and is no-way meant personal)

you may notice that there are no indicators here other than the plug

some caps are vented, i would say that the amount that leaked out from the "overfill" could still be an indication of a bad seal, or closed vent

speaking of which, anybody buy the plugs by the case...they are about 99cents each by the box and $4 each plus shipping by the each...

How about the Scotseal CR40091. This is a direct fit for the CR40086. The 40091 is Scotseal plus XL. This appears to be very similar to the triseal. I was unable to find a cross match for the triseal to fit the hub. The instructions also say to prelubricate the seal before installation into the hub and on to the spindle. The installation instructions say this can be installed by hand. The instructions also say it should be able to handle very minor deformities in the spindle or hub. That might be the solution for my problem?

Thoughts? Anyone used one of these?

The hub oil with warm up and if it's overfilled it leaks out until reaching a comfortable level. Mine did this every time I filled them or changed the oil. Once it found its nominal level it stopped leaking.

Not that particular seal # but I have been installing nothing but CR +XLs for better than 10 years. Two failures, one was explainable so one unexplained. I will not even install a Stemco unless a customer signs a waiver. Just make sure you "wet" them with gear oil just prior to installation. They swell with the gear oil to conform to many irregularities in both the spindle seal journal and the hub bore.
BTW the steel case CR (non Scotseal) can sit on the shelf along with the Stemco and National seals as far as I am concerned.
Carefully check the seal journal on the spindle or axle stubs for signs of some poor misguided rookie using a chisel to remove a Stemco wear ring. Some light filing may be needed if there is a line from a chisel.

Thanks Jim! I was hoping someone on the boards had experience with that seal or line of seals.

We had the opportunity to put 1100 miles on the bus this weekend. The first half of the miles were in 80+ degree weather. When I put the front wheel back together I used the CR Scotseal Plus XL wheel seal. I also made sure to check end play. My final end play was around 3 thousandths of an inch of play. After the drive I'm pleased to report NO wheel seal leakage at all. I really liked the XL+ seal and found it so very nice to work with. Hopefully this is the end of that wheel seal leakage saga. Anyway - love the XL+ seal.
