Cyl. Block, Liners, Pistons & Rods/Final verifications FINAL VERIFICATIONS 1. Rotate crankshaft several revolutions to be sure engine rotates without excessive tightness. 2. Check liners for deep scratches which would indicate an improperly installed or broken piston ring. 3. Check for proper side clearance in all rods. Each rod SHOULD HAVE slight side-to-side movement.

Place KJD10123 Gauge (with flat side up) on cylinder -UN-15NOV88 block so that indicator point rests on block surface. 2.
Set dial indicator at “zero”. L103012 3. While pressing gauge downward, turn crankshaft until piston is at “TDC” position. 4. Piston protrusion should not exceed 0.25 mm (0.010 in.) when KJD10123 is used. NOTE: If KJD10123 Gauge is not available, use a dial indicator. In this case, the piston protrusion -UN-07FEB95 should not exceed 0.35 mm (0.014 in.). 5. If protrusion is out of specifications, check all concerned parts to determine the cause.
