Clevite made in china WHAAAT? 
The latest clevite catalog does list oversize OD main bearings for the first time ever. There are numerous mistakes in the specifications.... which really made me wonder..... what they were UP to. Now I know. Looks ok from here.
THANKS for the pics. |
Can you please share the link of clevite catalog

Please do keep us posted as to how the new clevites measure/fit.

Got the bearings today, havent measured them yet but thought Id post pics for you all. Pretty disappointed that they are made in china vs. mexico but maybe it means the rod bearings could come back? In the hand edges feel rough compared to regular mahle or KS, weird copper sheen under certain lighting but overall standard aluminum color. #2 bearing is still steel backed fortunately.

Ray,
One of the tech guys I spoke to at Mahle told me I could run that bearing. The pictures I posted at the beginning don't show it very well but there is a grayish tint in the copper. What he (the tech guy) said was the copper showing is due to some kind of oxidation or a patina showing through due to it was an old unused bearing that was exposed to high humidity. I decided not to try it in my all new 2127 motor I am building. Sorry I didn't share that info earlier and glad you brought it back up.

Mmmmm.....not a very accurate answer you got from that "tech"....but thank you for going back to it! The outer coatings they typically put on bearings.....tin or lead/tin.....would not simply oxidize away without leaving considerable white residue. And....if there were oxidizing going on....the copper would not have been anywhere near that color. It would have been at best.....dark penny colored or going green.
But I do agree that if they were still the right size there was probably no reason you could not have used them. There are bearings made with outer copper layers.
I am betting as you noted that there was some visible gray coating....that they were simply not coated completely and they got missed by QC. Ray |

They quit making the good rod bearings for 780p VW 1600 and 610p 2" buick, and stock is depleted.
What good would main bearings do if we don't have rod bearings?? 
Those rod bearings fit 50 million engines, but I guess there is no demand???? |

might want to tell them to make them with only internal groves on all bearings....  3/4 groove would be even better... |

That's what I was also told by the Mahle tech guys. When they do get them in I am going to stock up on a couple of extra sets.

Bugsy, Thank you for the tip, your right that would be a quick way to measure the clearance.
I already installed that copper bearing in the case (torqued)and measured with a dial bore gage and the crank with micrometer and it has a clearance of .002.
I decided to buy a new set of main bearings as pictured above and move on with the build and those bearings all measure .002-.0025" clearance, perfect for me.

| Why don't you just slide the outer bearings on the crank, install the center main in the case and bolt together with plasti-gauge across the center split bearing. You'll know right away if the shell missed the last coating process, or if this a used bearing shell. Just did mine last night, took 15 minutes, and is almost fool proof. |

Yes the box says connecting rod bearings but they are not and this is the exact box the MAIN bearings come in straight from Clevite/Mahle. The part number is correct for the mains.
