1. Idle gear inspection
1) Measure the idle gear shaft outer diameter using a micrometer.
Note
- If the measured value exceeds the limit, replace the idle gear shaft.
| Idle gear shaft |
Standard value |
Limit |
| A |
44.950 to 44.975 mm { 1.7697 to 1.7707 in } |
44.80 mm { 1.7638 in } |
| D |
24.959 to 24.980 mm { 0.9826 to 0.9835 in } |
24.80 mm { 0.9764 in } |
2) Measure the inner diameter of the idle gear bushing using a dial gauge.
3) Calculate the clearance between the idle gear shaft outer diameter and the idle gear bushing inner diameter.
Note
- If the measured value exceeds the limit, replace the idle gear or idle gear shaft.
| Idle gear shaft |
Standard value |
Limit |
| A |
0.025 to 0.075 mm { 0.0010 to 0.0030 in } |
0.20 mm { 0.0079 in } |
| D |
0.020 to 0.062 mm { 0.0008 to 0.0024 in } |
0.20 mm { 0.0079 in } |
