| Post subject: | Bearings and Crankshaft |
Some of you have come across little miss Rodney on this forum - goes by the name of Shermn or something like. Anyway, the engine from her Mini has a worn key way in the crank. I've pulled the crankshaft out of my old engine - all but one of the areas where there were bearings (big end and main) are nice and clean, and the bearings too look good. I should be able to clean up the little bit of scratching on the one "suss" big end. Question - should I machine the crankshaft and get oversize bearings?? See ya |

You need to measure them with a micrometer, ot take to a crank grinder for quote, and they will. They won't grind if it doesn't need it. I get mine ground if there is more than .0005" (1/2 a thou) of taper or ovality. |

Umm... can the old crank be fixed or is it scrap metal?? If it's a common old Mini crank I'd simply find another as you have done. Not worth the hassle to fix it. If it was worth big bux like an S one, yes there are ways to reclaim it but they cost $$. |
