Problem 14471 piston wall clearance
Did you know?
WebbReason: piston pin bed has become hot due to insufficient clearance or a lack of oil. Damage assessment The piston pin boss has heated up excessively. The thin-walled and elastic piston skirt is able to compensate for the increased thermal expansion on the pressure and anti-thrust sides. The piston pin boss is stiffer and its expansion increases. WebbIf the clearance is too tight, then the piston can seize in the cylinder as it expands due to combustion heat. Diamond carefully specs the piston-to-wall clearance with each and every piston they sell, but checking it in relation to the bore is a mandatory part of the assembly process.
Webb3 sep. 2011 · This is what I used to measure the piston clearance. First I measured the piston, as per the manual by taking the micrometer and measuring 3/8" from the skirt 90 degrees to the pin. I took a dozen reading on each piston and this is what I came up with. Stock Piston Left Side: 3.3373" Right Side: 3.3366" If the clearance is too tight, then the piston can seize in the cylinder as it expands due to combustion heat.

Webb16 dec. 2007 · Unless the man that makes the piston is way off base I would be expecting the rings to end but and ring lands to fail. Prior machine shop had bored my block to .060" over and sized for .003" clearence, my machinist said .003 will break the piston the instant you get some marginal gas, so we bored it to .070" clearence at .002" ring gap at .022". G Webb26 nov. 2009 · Yes, the pistons are scuffed above the ring lands. I measured the clearance last night at the skirt and I could barely fit a .008 feeler gauge between piston and cyl wall there was no way a .0011 gauge would fit. I did not notice skirt being scuffed but will check tonight when I get home.
