approx 1989 on, colour coded bearing caps The 1275 cc A-plus series engines was equiped with colour coding main bearings from approx 1989 on. This bearings was not a set, the halfs was colour coded, matching to the engines colour coding by a special overview. No oversize was used, cause it was OEM. If your engine needs overhauling, in most cases oversize is neccessary and a grounddrilling is recomended, so use the main bearing kits recommended from approx 1984 on (lower half smooth with center location lip, upper half with groove and oilhole).
