Default Thrust Bearing Dimensions

My 2006 PT Cruiser automatic trans 2.4 non-turbo crankshaft walks and pushes out the crankshaft seal. I took the engine apart to replace the thrust bearings. The upper TB fits, but the lower new one does not fit. The locator tab is 2mm off. I tried two separate bearing sets with the same results. Where can I find the specs for the lower crankshaft cap to see if the locator tab slot is properly machined?
Thank you

Welcome to the forum

This is a known issue with a certain batch of the Gen2 PT's. Supposedly my PT falls within that batch, but mine has not experienced any issue, to date. From reading several other threads in this forum, it appears the problem occurs more on cars with a manual transmission.

Are you the original owner? If so, since it is a known issue with Chrysler, some members, in other threads, had reported that their issue was fixed under the powertrain warranty. The fix is that the block has to be replaced. However, if you are not the original owner, and you have already torn down the engine, you probably won't be able to get any relief from Chrysler.

Another 2007 failed engine: oil streaming - bad crankshaft thrust bearing

Please go to the Welcome New PT Cruiser Members section and introduce yourself and your PT.

Thanks. I am not the original owner. There is a salvage yard with several of them. Perhaps I can take one of those?

I wonder if it would be safe to grind off the locator tab from the new lower thrust bearing?

How many miles are on the vehicle? Did you buy it from the original owner, or from a lot? Was that the only issue that it had? Is the rest of the vehicle in good condition?

If you got it from the original owner and that was the only issue, too bad the original owner didn't get it fixed under the powertrain warranty.

Just curious, what is the date of manufacture of your PT? It will be listed on the VIN label on the drivers door, on the top line: DATE OF MFR

111,000 miles. That is the only issue I know of. I am the third owner. The previous owner said it started when he got it. 6/2005

I probably could, but the problem is that batch of years could have the same issues. That's a lot of time in the salvage yard. But, I may have to resort to that.

The other issue you have is, whatever motor you get, you should plan on replacing: timing belt, water pump, tensioner, idler pulley, cam seals, crank seal, center motor mount including new bolt.

Yours was an earlier build, my PT was made 10/05, so hopefully they fixed the problem by then, but I have not been able to find any accurate info on what batch had the bearing problem.

can you post a picture of the tab that's 2mm off?

i wouldn't use a bedplate from another block without having a machinist check and possibly line hone it. is that ok to just switch these from block to block?? asking, as i don't know.
