In case this helps someone, here's what I learned about 107 front wheel bearings:

The EPC lists TWO bearing kits for my car (1984, 107.046, 117.962):
107 330 00 51 on the front axle page
115 330 00 51 on one of the other front axle pages

I think the difference between the 107 and 115 kits is the oil seal. The 115 seal has an outer lip, as in this post, whereas the 107 kit has none. The FEBI kit 05422 here shows what my original seal looked like.

If you do a search for the 1073300051 part number on the EPC without vehicle and click on a 111 assembly it notes that 1073300051 replaces 111 330 00 51.

The *** online catalogue lists the dimensions of the inner bearing incorrectly (17.46 mm rather than 18.9), even though the bearings in the kit are correct. The dimensions on the febi catalogue for 05422 are correct.

The dimensions of the oil seal are 45-62-10/12 (ID-OD-height of metal/height of metal + rubber inner).

The oil seal in the *** kit was 64mm, whilst the bearings were correct. The *** online catalogue lists 4 different part numbers with the same bearings. Probably one of the kits has the correct seal.

The correct SKF kit is VKBA516 for my car. 517 may also work, but not 914 whose oil seal is again 64mm OD.

I ended up with a Firstline kit FBK144 whch was correct in all respects, but has the oil seal with the lip as in the previous linked post. This seal installed fine and seems fine. The bearings in this kit were all F.A.G. spain, whereas the bearings in the *** kit were a mix of *** and KOYO! The firstline kit also had the three-lugged star-shaped washer (mine were worn), a dust cap (couldn't get it on, so used my original), the electrical contact thing, and a strange spanner shaped thing that according to the EPC is not valid for my car.

This is all so confusing even I'm now confused writing this. To keep it simple here are my tips for ensuring you get the correct bearings + seal:

1) Remove all bearings, seals, races and measure with vernier callipers.
2) Ask every motor factor you know to order every kit that they think is compatible based on both your registration/VIN AND the MB part numbers.
3) Take the original parts and vernier callipers for a day driving around all your motor factors (in a car with 4 wheels on it). Better still get each shop to measure both bearings and the seal over the phone, and check the bearing numbers against the originals.
4) Keep driving until you find both bearings and a seal that has the same dimensions as the parts you took off and is made by a reputable manufacturer.

A trick to get the races out is to heat the whole area with a blow torch/camping cooker then squirt cold water on just the race, causing it to contract. Then hit it with the drift punch/chisel. This worked for me.

If anyone needs part numbers for the bearings let me know, I can probably dig them out. Right now I'm knackered and I can't find my notes. We should actually have a thread for a wheel bearing cross reference, i.e. which kits fit which cars and who makes the supplied bearings.

Oh and the kit I bought was £30 vs. £100 for MB oriignals. Could have probably got it cheaper on ebay but I've got 300 miles to drive tomorrow so couldn't afford to mess around.

Cheers.

Great post Turbo. Too bad you get hosed for MB parts.
I paid $70 CAD aside for mine...no measuring or dicking around.
 
1986 560SL front wheel seal ring writings

I dig my used front wheel seal ring from trashes, the writings on this 560SL -86 seal ring are:

011 997 6147
CFW A1
45-64-12/7
W.Germany

So it is most propably factory original, West Germany has not exists since the production era.

And the *** kit seems includ W107 Gen2 oil seals:

"The dimensions of the oil seal are 45-62-10/12 (ID-OD-height of metal/height of metal + rubber inner).

The oil seal in the *** kit was 64mm, whilst the bearings were correct. The *** online catalogue lists 4 different part numbers with the same bearings. Probably one of the kits has the correct seal."

OK further to my previous post here are the bearing part numbers for MY car:

Inner bearing: EK-LM11949
Inner race: EK-LM11910
Outer bearing: EK-LM67048
Outer race: EK-LM67010

I don't know what the EK means but I don't think it's important.

The MB part number on my seal was 003 997 93 46, but the other number written on the side was I believe the generic type/spec:
B1SLSF-45-62-10/12
cFw C204 (don't know what this means).
Google tells me this seal cross refs to a Corteco part: 01019288B
A bearing specialist informed me this seal corresponded to the type R23, as in e.g. this one. These seals are a standard component, and available from many bearing suppliers for as little as £2. Note it is nitrile rubber, and has a garter spring (type R21 is the same without the spring). It should also have a lip and 2nd 'wiper' lip on the part of the rubber that contacts the spindle.

On the EPC, Front Axle page "030 Steering Knuckle and Control Arm" lists the kit 115 330 00 51, whilst Front Axle page "11171 Front axle with ABS" lists the 107 330 00 51 kit. Notice the 107 kit does not include the strange three-lugged washer whilst the 115 kit does (and it was on my car). This piece may need replacing as it can be worn by the nut as it was on mine.

The *** kits that crossreffed to my car via the VIN/EPC part numbers were:
713 667 370 (right bearings, 64mm OD seal)
713 800 310 (just two of the above)
713 667 490 (crossreffed to the 107 number)
713 667 400 (crossreffed to the 115 number)

ALL of these kits stated the same bearing measurements:
Outer: 59.13x31.75x16.76 ODxIDxh
Inner: 39.88x17.46x14.61 ODxIDxh. This is incorrect, when I inspected the 713 667 370 kit the bearings were the correct size (19mm ID, i think 45 OD). Check the bearing supplier specs if you want exact & correct dims for these.
As I said the *** kit contained KOYO bearings for the inner, also one kit had the washer and dust cap and another (same part number) did not. Strange.

If I were doing this job again with more time this is what I would do:

1) Order the bearings and races from a bearing supplier to match the ones that came off the car. The supplier would be able to tell you for sure the manufacturer, whereas the automotive kits cannot. At £5 for bearing+race this would also be cheaper, and going on bearing part numbers should guarantee the replacements will fit.
2) Do the same for the oil seal.
3) If necessary, either order the strange three-lugged washers from MB or take the old ones to a machine shop with a lathe to be faced off.
4) Probably replace the caliper bolts and locking nut bolt, as some kits include these and it can't hurt.
5) The electrical contact spring thingy (what is it for?) is probably fine to re-use. Mine seemed fine.
6) Re-use the old dust caps, unless they are falling off. I couldn't get the new ones in (didn't try a sledge hammer!).

OK that's all my scribblings transcribed. Now I can chuck them. Hope this helps someone.
