The car I'm working is a 86 Merc 190D whit a OM602 (2.5L )
Job: Head gasket - timing chain / oil pump tensioners - front crank oil seal
First talking about seals .
I ordered and try to install Elring Klinger and find out that the fitting it's loose. Seals has to be force /pond in the housing , I made a short video clip on YT showing the Erling seal . https://www.youtube.com/watch?v=vYpYdmiq8GQ
I remove the crank hub and I was surprise haw soft the steel it is, you can se in the picture the pitting and grooves .
I decide to repair it, I hope this thread is going to be helpful for somebody . spending hundreds of $ is out of option .
I order a seamless stainless pipe (stay away from welded pipe ) whit a ID 42.88 mm the OD of the hub is 45 mm, so I have to turn it dawn 1.06 mm and press fitted over the hub . It's plenty of material left over the key 3.44 mm from the total of 4.50 mm to be exact .
I'll be posting in a week whit more pictures but first i'm waiting for the pipe to arrive.

That wear damage on that hub is pretty significant, but I suspect a more inexpensive and more readily available fix would be the standard TIMKEM Redi-Sleeves repair sleeve KWK99177. These are available almost everywhere auto parts are sold for about $25.

That is the part number to fix the hub used on a 603 engine which I think is the same on the 602

Thx Top Knot .
It's the same size i Just been on timken site and verify it's 1.769 inch but i don't now see the thickens of the sleeve .
let's assume it's 0.020 if it's any thicker the only way i see it its to compensate whit a different ID oil seal , never use repair kits before so I don't know details .

I have used many repair sleeves on domestic cars over the years. They work great. To make the job easier, heat the new sleeve in hot oil and put the hub in the freezer over night It should just slide on. If you just try to drive it on with a hammer, you only have a 25% chance of it going on. The difference in the hub size is not a problem and the stock seal will be fine.

Good luck

The sleeve is made of highly polished stainless steel material .25 mm thick
and therefore only adds .5 mm increase to the diameter well within the tolerances for the standard seal. But if that was a serious concern a slightly larger ID seal can be had. I think TIMKEM actually sells a kit with a sleeve and a matching seal, at least they do for some standard shaft sizes.

Here is the TIMKEM Small Dia Catalog,

Precious information from you guys , Thank You .
I'll apply the heat / cold treatment for sure .
Now that I have this info . i'll do the next job using the kit but for now I want to try the lathe path.

Another company sells speedie-sleeve. Some companies that make the repair sleeves sell the Seals with them so that should alleviate any concern about the seal.
