Had a call from Colin this afternoon, he wanted me to come over and lay down some policy guidelines for the Crankshaft. The problem is, how long is a piece of string? Things we make are generally imperfect and what we built 100 years ago are somewhat more so. The question is how good do I want it and the answer has to be good enough to get me through the next 4000Km rally without trouble and then some. The last thing I want is to be sitting on the side of the road with a broken car wishing I had sold my children into slavery in order to have the perfect unbreakable crankshaft.<\/p>\n

Colin has found the following problems:<\/p>\n

    \n
  1. The conrod is not straight although the big end the little end are parallel, the rod is “S” shaped and is scraping the inner flywheel.<\/li>\n
  2. The inner flywheel to output shaft taper is wonky (not his words)<\/li>\n
  3. The big end journal had been previously machined making one of the tapers\u00a0 seat about 60% however this is not the drive side so is probably OK<\/li>\n
  4. One of the crankcase breather “Flapper” valves is missing and because of previous modifications may be hard to rectify.<\/li>\n<\/ol>\n
