f22b1 main bearings
muy f22b1 vtec engine has 22222 stamp on crank and ccbcc stamped on block which comes out to y/g,y/g,y,y/g,y/g. (that's yellow and green.)
with yellows in the block and greens as well..(I know it meant one half yellow one half green, but I wanted to see the difference in the bearings...)the yellow had a clearance of .0020, which is the service limit for journals 1,2,3 & 4... here are muy books' readings -oil clearances- # 1 &4 standard .0005-.0015 service-.002 # 2 standard .0008-.0018 service-.002 # 3 standard .0010-.0019 service-.0022 # 5 standard .0004-.0013 service-.0016 I also tested browns and acl bearings. these are the clearances I got with a dial bore gauge..... green bearings- .0019 yellow bearings- .0020 brown bearings- .0015 acl bearings- .0025 any ideas |
