Calculating cylinder bore to piston clearance
WebMar 31, 2002 · Generally 0.001" per inch of diameter is a good rule of thumb, for forged pistons it is more like 0.0015" to 0.002" per inch of dia to accomodate the denser material expansion. More than this and the rings will wear faster due to the piston rocking in the bores. I have successfully run 0.007" clearance in 4" bores with cast pistons with a light ... WebThis will no longer apply as the cylinder wears with age! Clearance or Fit :- In general 125 - 250 pistons will need a clearance of 0.040 - 0.050mm. 60s and 80s, a little less. So a bore measuring 53.99 will need a piston size 53.94/5. This will usually be an A or B grade piston. A bore measuring 54.01 will need a C or D.
