Dismantling
| PERFORMANCE ORDER | | 1. Remove the cylinder head, timing belt, front cover, flywheel, pistons and crankshaft. |  | 2. Special adaptation (09260-32000), remove the oil pressure gauge. |

Check
| PERFORMANCE ORDER | | 1. Remove the engine block gasket remnants, sealant, dirt, oil, grease and other foreign material. Visually inspect the cylinder block for rust, corrosion, cracks or any other defects. |  | 2. Clean the mating surfaces of the cylinder head and cylinder block from the remnants of lining. Metal ruler and probe in six directions check the flatness of the mating surface of the cylinder. Deviation from flatness of 0.05 mm
The maximum deviation from flatness: 0.1 mm |  | 3. Measure the diameter of the cylinder in diametrically opposite directions in three dimensions by adjustment cylinders. If the diameter of the cylinder exceeds the limit, have round or tapered surface of the cylinder or damaged or production, it is necessary to bore the cylinder block and install new pistons and piston rings of the repair sizes. Nominal Bore: 75.5 mm
The taper of the cylinder: not more than 0.02 mm | | 4. If the top of the cylinder has a step, cut it with a special tool. | | 5. As the parts are supplied pistons increased four sizes: 0.25, 0.5, 0.75 and 1.00 mm. | 6. When the cylinder bore to the nearest oversized soak clearance between the piston and the cylinder and make sure that the pistons are of the same size increased.
Measure the outside diameter of each piston race at 90 ?� to piston pin at a distance of 12 mm from the piston skirt.
The clearance between the piston and the cylinder: 0,025-0,045 mm |
