The sleeve is a very thin stainless steel ring that presses lightly onto the shaft, spindle, yoke, etc. seal surface. The sleeves are available in a variety of sizes and widths for different situations. All use the standard seal, and have a excellent seal surface finish, which is more abrasion resistant than the surface it covers. The sleive is recomended for covering damaged surfaces as well as new surfaces that could use renewable surface protection, as the sleeve can be removed and replaced easily as needed without deterioration of the underlying part.
I use and recomend using sleeves when possible anytime a new part is installed as the sleeve will outlast the part surface many times, gives a better finish (better sealing), and is replaceable in the rare instance it is required.
All seals have a shaft size range of tollerence for installation. The sleeve is thin enough as to not get out of the range for the original seal. In some instances, the slight increase in shaft size may help improve the sealing of worn undersize shafts (like a spindle seal surface someone has sanded on repeatedly), however, if the shaft is too far undersize, the standard sleeve for the part design dimension may not fit, being too loose. In that case, even with the sleeve, the sealing will be compromised, and the part should be replaced, with a new sleeve installed.
The benifits of the sleeve on new parts will be greatest on applications subject to contaminations with abbrasive material or long life usage, typical of offroad conditions, trucks, equipment, etc. while with highway driven vehicles subject to low mileage (grocery getters), the benefits may not be seen as readily. Sometimes the cost of the sleeve approaches the cost of the part, and if you are not having a part wear problem, the benifit is not there.
Proper choice of seal type and quality are also important to long term success. Do not just take the generic junk the child on the counter at DAP or AZ tries to hand you. Be sure you are getting the right stuff.
The part is cleaned, the sleeve is pressed (driven. etc) onto the part, the parting line between the surface of the sleeve and the part should be checked for sharp edges, lips, or burs, reclean, and then assembled as usual. If need be, a good small file can touch up or round off any roughness found. Be carefull not to slip and scratch the sealing surface.

hey all new mudhead here.i have a set of selectro hubs,and i never had a set of these till i bought this jeep.they have a 1/4 inch bolt in the face of the hub.i looked at these for awhile till i figured out you can unscrew them and put in a zerk fitting.not long ago i was out in the mud and about a week later my front wheel bearings started screaming so i tried it out and it worked like a champ!not trying to hijack this thread ,(but)does anybody know about these hubs.i have had 4 78 cj-5's and all have had warn premiums.i was a little worried about the strength of these but i havent hurt them yet.they are 1/2 turn,and the whole face of it is the knob.later YEAH HE SAID MUD!!!!

Not a hi-jack CJ5, info. I had a set of those on my 75 CJ5 and I broke the axle not the hub. Well, actually I broke both axles, windshield, bent the frame and he roll bar. With the right gloves it was easy to turn'm even after the mud :? Needed gloves to "get a grip" :lo1l:
Welcome to the board and the thread!!
