That could be it…TIS doesn’t leave a very good bread crumb trail on the m62 for this work. I hope you are right, because I speccced bearing 1 with plastiguage today and it was dead in the middle of the allowable tolerance, at .038mm.
It does seem to me that there are several “yellow” shell sizes so I’m still unsure which to buy. It doesn’t help that my crank doesn’t bear any of the markings TIS talks about. Once again, the 4.4 TIS info is sparse, but I do think the yellow dot in the pic above means that yellow shells were used….maybe…
