ĐÃ dùng mọi thủ đoạn cuối cùng cũng down được
Nhưng bác có số đo của trục,bạc trục,bạc biên,piston không ạ.Bên em đang làm trung tu em này nhưng không có tài liệu nào cả.
Bạc biên nè:
Measure the rod bearing shell thickness with an outside micrometer that has a ball tip.
Standard Connecting Rod Bearing Thickness (Used)
mm in
2.43 MIN 0.096
2.47 MAX 0.097
The bearing
must be replaced if it is below the minimum specification.
Measure the side clearance between the connecting rod and crankshaft.
Connecting Rod Side Clearance
mm in
0.10 MIN 0.004
0.33 MAX 0.013
Bạc trục đây
NOTE: Oversize service main bearings are available for reground crankshafts.
Main Bearing Sizes
Standard (cos 0)
Oversize
- 0.25 mm (0.009 in) (cos 1)
- 0.50 mm (0.019 in) (cos 2)
- 0.75 mm (0.029 in) (Cos 3)
- 1.00 mm (0.039 in) (cos 4)
Use an outside diameter ball-tipped micrometer to measure the main bearing shell thickness.
Standard Main Bearing Shell Thickness
mm in
3.446 MIN 0.1357
3.454 MAX 0.1360
Discard any main bearing shell if it is below the minimum specification.
Measure the thrust bearing flange thickness. Measure both the front and rear flange of the thrust bearing.
Thrust Bearing Flange Thickness
mm in
3.52 MIN 0.139
3.57 MAX 0.141
NOTE: The thrust bearings are available in 0.25-mm [0.010-in] and 0.50-mm [0.020-in] oversize thicknesses.
Đây là piston, chả biết bác cần những gì ở piston
Measure the piston bore when the piston temperature is at 20°C [68°F].
Piston Pin Bore Inside Diameter
mm in
45.01 MIN 1.772
45.03 MAX 1.773
NOTE: Add 0.013 mm [0.0005 in] to the piston pin bore inside diameter per 5°C [10°F] temperature rise up to 32°C [90°F].
The piston pin bore must be checked closer to the outside diameter of the piston since the piston pin bore is tapered.
Inspect the piston pin for scratches, grooves, or other damage.
Measure the piston pin outside diameter.
Piston Pin Diameter
mm in
44.99 MIN 1.771
45.00 MAX 1.772
NOTE: Discard the piston pin if it is more than 0.03 mm [0.001 in] out of round.
Measure the piston skirt diameter as illustrated.
Piston Skirt Diameter
mm in
113.81 MIN 4.481
113.88 MAX 4.484
Use a micrometer and piston ring groove gauge, Part Number 3823966, to measure the wear of the top ring groove keystone angle. Use piston ring groove gauge, Part Number 3823965, to measure the wear of the intermediate ring groove keystone angle.
Piston Ring Groove (Keystone Angle)
mm in
Top Ring: 113.94 MIN 4.486
Intermediate Ring: 114.32 MIN 4.501
