BORE CYLINDER
БЛОК ЦИЛИНДРОВ - РЕМОНТ
- УКАЗАНИЕ:
Bore all 4 cylinders to fit the O/S piston outside diameter.
Replace all the piston rings with ones to match the O/S pistons.
| 1. BORE CYLINDER |
Prepare 4 new O/S pistons.
- Standard piston diameter:
Item Specified Condition O/S 0.50 99.950 to 99.980 mm (3.935 to 3.936 in.)
Using a micrometer, measure the piston diameter at right angles to the piston pin center line where the distance from the piston head is as specified.
- Standard distance:
- 61.27 to 61.33 mm (2.412 to 2.415 in.)
| *1 | Front Mark |
| *2 | Size Mark |
| *a | Distance |
Calculate the amount each cylinder is to be rebored as follows.
- УКАЗАНИЕ:
Size to be rebored = P + C - H
P = Piston diameter
C = Piston clearance: 0.040 to 0.060 mm (0.00157 to 0.00236 in.)
H = Allowance for honing: 0.02 mm (0.000787 in.) or less
Bore and hone the cylinders to the calculated dimensions.
- Maximum honing:
- 0.02 mm (0.000787 in.)
- ПРИМЕЧАНИЕ:
- Excess honing will destroy the finished roundness.
