Hey all,
I am apparently having some sort of a brain lock up condition. I am reassembling the front hub/rotor area and am stuck at the hub seals of all things. The seal part # I am using is CBC2858. Ill admit my ignorance and say that I haven't seen a seal quite like this one before. I have looked it up and in comparison to the part listings' drawings it appears to be correct and I believe that, again as to the drawings, I am installing it in the right direction with the wide flange away from the bearings. This is how the old ones were installed too.
The method I tried to use was such as I have used in the past without issue. Using a suitable size socket and a hammer firmly tap the socket into the hub until it seats. I got it to seat in the hub only after much sliding around, it being greased rubber. I then installed the hub onto the axle stub gently till the seal met the raised area on the axle. I was able to slide the hub and seal onto the raised area but after installing the outer bearing, "D" washer, and nut I had difficulty spinning the hub even with no preload on the bearing. I then pulled the hub back off to see if my error was obvious and the seal stayed on the axle. I was able to pry it off by gently pushing a flat screwdriver behind it. It appears undamaged but I am not sure I should try to use it again.
So my question is what am I doing wrong?

The grease seals that came with my new bearings looked like standard oil seals, with a spring internally etc etc, and they fitted very firmly into the hub. Are yours just rubber or plastic, with no spring inside? If so, I would buy some normal ones.

 

MMMMM,

My parts list states C45711 UP TO Vin 147268.

Then that CBC2858, but NO Vin breaks, and that is confusing.

My memory???, has those hub seals as a Metal cased Flaseal with the spring as a tension aid to the spindle.

I do not remember rubberised cased seals in that position.

I also find NO superseding of the C45711 to any other number, and that means its still a current number.

 

Thank you guys, As it happens I already fell into the "no vin break" trap on Rock Auto. They only have the metal frame with a spring seal listed which is what I ordered first- the National 473454. Looking at the Jaguar site I find that the difference appears to be the inclusion of the antilock brakes and having that reluctor wheel on the hub. Anyway, the metal seals I had were probably 1/8" too big diameter. There was Just No Way those would work.
I also looked at the Kirby Palm book. It mentions the wheel seal, the way it rides on the hub and how the hub must be very smooth but does not (that I saw) give any hints as far as installation.
I got these seals from Moss motors. I deal with them a lot and have had good luck. I am however wondering if maybe these are still not the right ones. I may just have to crack open the old checkbook and spring for some Gen You Wine Jag parts for once.
Still hoping for a simple answer>>>>

 

It's been a while since l did these seals but as l remember the post ABS seal did not mount to the hub in the way the traditional pre ABS seal did.
It tended to stay at the root of the stub axle and the hub rotated about it rather than it rotate with the hub.

 

Could it be that the seal should be installed to the axle stub and then the hub/ brake rotor onto that? Reverse of the way I did it? I am not sure why that would make a difference though...

 

This sounds very familiar. I looked at pics of the CBC2858 and it's the same seal I did battle with on my X300/XJR. FWIW, the X300 manual calls for the seal to be installed onto to stub axle first. Then the hub. Then you tighten the hub down onto the seal. You're in essence using the hub itself as a press to install the seal. I ruined several new seals before getting the correct seals and before learning the the seal goes on first. After that I reused the seals, as after a bit of use they're easy to install onto the hub in a conventional manner.

Cheers

Thanks Doug, I tried my other new Seal from Moss on the other hub clean with no grease. I just don't see it working. I see heat build up and melting. Call me old fashioned but how can you set the bearing load when the hub won't spin? In any case I took a hard right turn from my normal routine and ordered a pair of seals from my "Local" Jaguar dealer with whom I have not dealt before. The lady was quite friendly and seemed to "have a clue." The seals are not expensive so we shall see. Axle first seems somehow fitting for a Jaguar, doesn't it.

 

I have completed this chapter in my "XJS struggle." At the same time as I initially posed this thread, I also asked it of Moss Motors from whom I got the second set of seals. They very kindly confirmed the process of putting the seal of the stub axle first by emailing me the proper shop manual pages. (Thanks guys!) I then, as stated tried the second seal I got from them but I still felt it was too tight, so I ordered a pair from Jaguar through my "local dealer" 50 miles away. The Jag seals are slightly different in that the smaller flanges that the hub slides on are slightly thinner allowing for less rolling resistance once assembled. I also hit up my hardware store for a short piece of 2" galvanized pipe to use as a driver- it is almost the prefect diameter. I ran the business end of it over my belt sander for just a few seconds to flatten and smooth off any sharpness. It worked very well and I have marked it and put in the drawer with other drivers and pullers. Thanks for your comments!
