W123 102 engine thrust bearings
Hello, I have a question about replacement of the thrust bearings on the 102 engine crankshaft. Can this task be done with the engine in the car by removing the oil sump or would the crankshaft need to be removed. Thanks for any infomation.

There would be no reason to do such that wouldn't also require removing the crankshaft.

* What is your reason for replacing the thrust bearings? Your problem could likely be something other than thrust bearings.

If you get the pan off, the thrust bearings should be removable. But, as already asked, why? Does the crankshaft exhibit excessive endplay?

Let the truth be know to all!!!
Ok I have to confess. I made a bad decision. I rebuilt this 2.3 ltr engine and installed all standard size bearing on the crankshaft and rod journals. I miked all the races to verify the use of new standard size bearing, but for some reason I believe it was that my parts supplier did not have standard size thrust bearings at the time I used first oversize on the thrust. Well now after the engine warms up, The engine starts to squeal. I checked everything; water pump replaced all belts checked and replaced, timing chain check and replaced, camshaft checked. My only conclusion is the thrust bearings are too tight. This is why I want to jack up the car drop the pan and replace the thrust bearing without removing the crankshaft. Ok I feel better now that I have told the truth. But I still have the squeal to solve.

You can check the endplay, using a dial indicator, without taking anything apart. If it's too little, drop the pan and change the thrust bearings.
