                CAUTION This inspection is very heat sensitive. Do not check pis- ton running clearance immediately after honing or deglazing cylinder. Even holding the piston in your hand for too long can cause measurements to vary by as much as 0.0002 in. (0.005 mm). Both piston and cylinder must be at room temperatures before proceeding.  NOTE Piston measurement is taken on the bare aluminum to avoid measuring errors. An oval-shaped opening is present on each side of the piston for proper placement of the microme- ter. See upper frame of Figure 3-124. The oval openings are too small for a standard flat anvil micrometer which would result in measuring errors. Use








                                                         as follows:
