Piston Pin Replacement

1. With piston removed and cleaned, mark piston-to-rod to ensure proper reassembly. Using Piston Pin Remover/Installer Set (D81L-6135-A for 1.3L or D90P-6135-AH for 1.6L), place piston and rod assembly in press.
2. Apply pressure and press piston pin from piston assembly. Keep all removed components together for reassembly. Remove piston and rod from press and inspect.
3. Using a micrometer, measure piston pin O.D. in several areas. Measure piston pin I.D. Measure I.D. of piston pin bore and rod pin bore. Replace components if not within specifications. See, at end of article, PISTONS PINS & RINGS  table in ENGINE SPECIFICATIONS
4. If measurements of rod, piston and pin are within specification, reassemble using piston pin assembly set. Ensure piston-to-rod position is proper, with connecting rod oil groove on side of piston marked "F" or by a notch. Lubricate pin with engine oil before reassembly. With piston assembly reassembled, rod should fall by its own weight with piston held horizontally. Repeat procedure for remaining pistons.

Rod Bearings Check rod bearing for abnormal wear. Check crankshaft journal. Check rod bearing-to-crankshaft clearance with Plastigage. Machine or replace as necessary. See, at end of article, CRANKSHAFT MAIN & CONNECTING ROD BEARINGS  table under ENGINE SPECIFICATIONS.
