3. With a micrometer or caliper at a right angle to the piston pin<br />
bore, meausre the piston 11 mm (0.433 in) from the bottom<br />
of the skirt.<br />
4. Subtract the piston diameter from the cylinder bore diameter<br />
in order to determine piston-to-bore clearance. Refer to<br />
<strong>Engine</strong> Mechanical Specifications.<br />
5. If the proper clearance cannot be obtained, then select<br />
another piston and measure the clearances.<br />
If the proper fit cannot be obtained, the cylinder bore may<br />
require honing or boring.<br />
6. When the piston-to-cylinder bore clearance is within<br />
specifications, permanently mark the top of the piston for<br />
installation into the proper cylinder.<br />

Caution: Avoid contact with HOT components. Wear safetly<br />
glasses and protective gloves to avoid personal injury.<br />
Notice: Applying excessive heat to the connecting rod may<br />
damage or distort the rod. Rod temperature SHOULD NOT<br />
exceed 315°C (600°F). At this temperature, the end of the<br />
connecting rod will turn a straw color upon visual inspection.<br />
Notice: After the J 24086-C installer hub bottoms on the support<br />
assembly, DO NOT exceed 35,000 kPa (5,000 psi) or the tool may<br />
