piston protrusion - n0v0s - 31-05-2012
how many mm do the pistons in an xud protrude by? Accuracy is key here..
Quick answer appreciated as, quite ironically, i have my grinder out ready...ooh err

Is it not in the guide that I posted in the XUD section where you just posted this??

Yeah i could of sworn i read it in there, ended up finding it - page 3, 56 or something midway through. Found above link first, easier to find :p
Going to practice grinding on a scrap renault block/pistons before taking to the xud block. Shame it protrudes less than a 1mm though :/ which is what i want to lopp off ideally..!

IIRC each block needs measuring individually due to differences in manufacture and the possibility its previously been skimmed.
Easy to do, pop 2 pistons at TDC, run a straight edge between them and stuff feeler blades between the straight edge and the block face.
