Measure the piston pin-to-piston clearance. Piston Pin-to-Piston Clearance: Standard (New): 0.010 - 0.020 mm (0.0004 - 0.0008 in.) Check the difference between the piston pin diameter and connecting rod small end diameter. Piston Pin-to-Connecting Rod Interference: Standard (New): 0.016 - 0.036 mm (0.0006 - 0.0014 in.)

Reassembly Assemble the piston and connecting rod with the connecting rod oil hole (A) facing the ''IN'' mark (B) side. Insert the pilot collar (A) into the piston and connecting rod. With the embossed mark facing up, place the piston assembly (B) on the special tool (C). Be sure you position the recessed flat on the piston against the lugs on the base attachment. Press the pin (D) in with the pin driver (E) and a hydraulic press.
