I'm building a 406, the mains were turned 0.001" under. I plastagauged the mains this past weekend, the clearance was only 0.002". There was a quality issue with the bearings, so I'm getting new bearings, but I was going to go with King bearings, but I can only find them in STD or 0.010"... My question is can I go with STD King bearings or should I go with 0.001" bearings from another brand?( I had Clevite's before)
you can get kings in 001 if you go to a H bearing . if you had clevite s then why not use them ? they are ok most of the time . i use kings but they can come in bettter on wall size on bearing to bearing out of the box. but may not come in at the same clearance as what you had in the engine . i do not use plastigauge for hand fitting the bearings. you may want to check it with a bore gauge. i would start at a std king race bearing if for HP use.what happen to the old bearings ?
My clevite's had some pitting issues. They were new out of the box and almost half had issues.
they new old stock ? sound like they got damp ?.back over 20 +years ago they would do that and some guy s used a gray scuff pad and bust off the flash coating .i have had clevite s off on size thats why i run the KINGs but they do not come in like clevite s for sizeQuote:
