Fitting Pistons
- To determine if piston-to-cylinder clearance is within specification, see PISTON MEASUREMENT table. Measure piston skirt diameter from top of piston, at 90-degree angle to piston pin. Different piston sizes are used. Piston size can be identified by letter (size mark) stamped on top of piston. See Figure .
- Size mark on piston is a letter corresponding to piston diameter. Ensure piston diameter is within specification. See PISTONS, PINS & RINGS table under ENGINE SPECIFICATIONS.
- Check cylinder bore to determine piston-to-cylinder clearance. Clearance should be within specification. See PISTONS, PIN & RINGS table.
PISTON MEASUREMENT
| Engine Size | In. (mm) |
|---|---|
| 1.6L DOHC | 1.181 (30.0) |
| 1.8L DOHC | 1.299 (33.0) |
NOTE:
Different cylinder bore sizes are used. Bore diameters are identified by marking on cylinder block. See CYLINDER BLOCK under CYLINDER BLOCK ASSEMBLY
under OVERHAUL.
