Re: [MBZ] Wheel bearing replacement
I can't take full credit for it, I'd read about using weld as a way to get pistons out of stuck tractor engines. In fact at some point I'm probably going to need to do it on my 1928 Farmall. -Curt Date: Wed, 24 Nov 2010 15:41:03 -0800 (PST) From: Dimitri Seretakis dsereta...@yahoo.com To: Mercedes Discussion List mercedes@okiebenz.com Subject: Re: [MBZ] Wheel bearing replacement Message-ID: 112675.23627...@web113201.mail.gq1.yahoo.com Content-Type: text/plain; charset=us-ascii Creative solution!

Re: [MBZ] Wheel bearing replacement
Easy way to get pressed in sleeves out, too, although you must be VERY careful to avoid significant penetration of the weld to avoid welding the sleeve to the block rather than shrinking it. MB wheel bearings will always drive out. The factory tool helps quite a bit on tight ones, but a good soft steel punch works great. Not a hardened steel one, not a brass or aluminum one, just a soft steel punch ground straight across. Make sure you put the new race in right way 'round -- it's MUCH harder to get out when there is no lip to drive against.

[MBZ] Wheel bearing replacement
I'm trying to replace the front wheel bearing on my 71 280SL and I'm having a hard time driving out the smaller race (the one closer to the lock nut). I tried with a brass punch but the harder metal of the race chewed it up. I then tried a pin punch for driving out brake pad retaining pins but it just slips as the edge profile of the race is not enough to get a good grip. Any other tips? Does putting the hub in the freezer help? ___ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

Re: [MBZ] Wheel bearing replacement
Well I managed to get the race out. I pounded on it with the tip of a large screwdriver. The bearing was making an awful sound but it didn't look all that bad when I got it apart. The smaller race definitely had some bluing but no blatant scoring or pitting. I hope this was the problem. Hopefully it's not some other non bearing related thing that I'm not aware of.

Mitch ___ Never did an SL, but on other cars I ground a slightly angled flat on the end of a long drift punch and used the sharper edge of the punch to gently tap the outer race all the way around; tapping the opposite sides alternately. If I was installing a new bearing, I tapped much harder with a bigger hammer. Never failed to get one out that way, but there is always a first time of course. If the bearing had run hot, I soaked it with WD-40 and Rust Eater (from Autozone) for several hours, and then with light machine oil for an hour or so. If the bearing was stuck hard, I sometimes had to grind the end of the punch several times.

Re: [MBZ] Wheel bearing replacement
Use a soft steel punch. You may need to sharpen it a couple times by grinding it flat on the end. Timken bearings are great, but the races are a tight, tight fit.

Re: [MBZ] Wheel bearing replacement
I had the exact same problem on a 201 a couple years ago. I ran a bead of weld across the race in 3 or 4 places. The theory is when the weld cools it'll contract and pull the race in with it.
