anyone use a BEARING RACE INSTALLER ? any info on this device would be helpful. Do they come in different sizes? anyone know which style for my 1998 c class front wheel

Check out your local auto parts store. I bought a bearing race set from Pep Boys. Also, check online for Lisle or K-D brand. Regards.

i just use the old race that is being replaced, once out it makes a good tool for installing the new ones

AutoZone has a bearing race installation kit for rent.

Any one have any problems keeping the clamping nut on the drivers side wheel bearing? I replaced the wheel bearing inner and outer, and the clamp fell off good thing I was not on the freeway. and secrets to tightening. I'll just guess I did not tighten it up. BTW I need a clamp any body got one they want to get rid of? 1985 300 sd
thanks
thom

your wheel clamp has a 5mm allen head screw?

did you tighten up the clamp then hit with a mallet then back off the clamp, repeat, then set for end play?

BTW i used a Lisle bearing nstaller kit that I purchased from JC Whitney and it worked very well. For me it was easier than using an old race.

Remember: on the c-class install the inner bearings inner race and bearings before installing the grease seal.

Yes that i the one I have 5m alen wrench cap screw. I failed to hit it, and I may have loosened it to assure a good fitment. any hoo it fell off and I lost the clamp/nut and outer bearing.

I used the old race to install. Do the new outer bearing sit flush with the hub? and the grease seal also? I noticed that both seemed to be about an milimeter so from being flush inside the hub. .. in other words it seemed they should have been set further in, but I am confident that I seated them all the way down. perhaps I got a set that was not quite what I ordered, as the grease seal was too big a circumference (had to reuse the old one) and the new grease cap was too small. maybe the folks who sold the bearing to me sold the wrong set??? I bought from a different vendor this time.
thanks for your knowledge and assistance, and I'll smack it this time with a mallet (wood,. I have one).

the grease cap seems to be to small when first trying to tap it on, trick is to tap with some force the edge of the cap while going around in a circle.

new outter bearing races should fit just like the old one - not sticking out beyond the hub at all

you should compare all the sizes with the original components to verify.

I'll be sure to mic the new old and the ones that failed. if they are the wrong ones I'll let the vendor know and hope he makes it right with me. thanks for the info. BTW can you direct me to the best "reasonable" repair manuals? I have some for my Jag, on CD and paper, but wonder what is the consensus here on what to get . thanks again thom

what year and model?

Me too.

thanks thom

Best books would be the two volume set of the 126 chassis manual from MB and the OM617 turbo manual also from MB.

I use a hot plate or a coffemaker and heat the new race up to expand it, then pick it up with gloves because it is HOT and slide it on the shaft. I learned this technique from rebuilding woodworking moulders that high precision bearings. They actually had a bearing race heater that was an aluminium stepped cone with a heating element.

However, I did not know that the fit on any axle bearing was so tight that you need a bearing race installer. I recently did my W123 front wheel bearings and everything slid nicely on to the axle. When you tighten the axle nut it clamps the inner races to the axle.

I'm cofussed I can see this for certain applications but not front wheel bearings. They slide right on at ambient temp.
